+## Pipeline/worker related info

+If you need to do any worker/pipeline related work, search for "Pipeline" classes and their "create" or "build" methods to find the main processor sequence. Look for task orchestration patterns (like "chord", "group", or "chain") to identify the post-processing flow with parallel execution chains. This will give you abstract vision on how processing pipeling is organized.

+## What is Reflector?
+
+Reflector is a web application that utilizes local models to process audio content, providing:
+
+- **Real-time Transcription**: Convert speech to text using [Whisper](https://github.com/openai/whisper) (multi-language) or [Parakeet](https://huggingface.co/nvidia/parakeet-tdt-0.6b-v2) (English) models
+- **Speaker Diarization**: Identify and label different speakers using [Pyannote](https://github.com/pyannote/pyannote-audio) 3.1
+- **Live Translation**: Translate audio content in real-time to many languages with [Facebook Seamless-M4T](https://github.com/facebookresearch/seamless_communication)
+- **Topic Detection & Summarization**: Extract key topics and generate concise summaries using LLMs
+- **Meeting Recording**: Create permanent records of meetings with searchable transcripts
+
+Currently we provide [modal.com](https://modal.com/) gpu template to deploy.
+
 ## Background
 
 The project architecture consists of three primary components:
 
-- **Front-End**: NextJS React project hosted on Vercel, located in `www/`.
 - **Back-End**: Python server that offers an API and data persistence, found in `server/`.
-- **GPU implementation**: Providing services such as speech-to-text transcription, topic generation, automated summaries, and translations. Most reliable option is Modal deployment

 ```bash
 uv run python -m reflector.tools.process path/to/audio.wav

+```
+
+## Build-time env variables
+
+Next.js projects are more used to NEXT_PUBLIC_ prefixed buildtime vars. We don't have those for the reason we need to serve a ccustomizable prebuild docker container.
+
+Instead, all the variables are runtime. Variables needed to the frontend are served to the frontend app at initial render.
+
+It also means there's no static prebuild and no static files to serve for js/html.
+
+## Feature Flags
+
+Reflector uses environment variable-based feature flags to control application functionality. These flags allow you to enable or disable features without code changes.
+
+### Available Feature Flags
+
+| Feature Flag | Environment Variable |
+|-------------|---------------------|
+| `requireLogin` | `FEATURE_REQUIRE_LOGIN` |
+| `privacy` | `FEATURE_PRIVACY` |
+| `browse` | `FEATURE_BROWSE` |
+| `sendToZulip` | `FEATURE_SEND_TO_ZULIP` |
+| `rooms` | `FEATURE_ROOMS` |
+
+### Setting Feature Flags
+
+Feature flags are controlled via environment variables using the pattern `FEATURE_{FEATURE_NAME}` where `{FEATURE_NAME}` is the SCREAMING_SNAKE_CASE version of the feature name.
+
+**Examples:**
+```bash
+# Enable user authentication requirement
+FEATURE_REQUIRE_LOGIN=true
+
+# Disable browse functionality
+FEATURE_BROWSE=false
+
+# Enable Zulip integration
+FEATURE_SEND_TO_ZULIP=true

+title: Data Independence
+---
+
+# Data Independence & Privacy
+
+Reflector is designed with privacy and data independence as core principles, giving you complete control over your data and processing.
+
+## Privacy by Design
+
+### No Third-Party Data Sharing
+
+Your audio and transcripts are never shared with third parties:
+- **Local Processing**: All ML models can run on your infrastructure
+- **No Training on User Data**: Your content is never used to improve models
+- **Isolated Processing**: Each transcript is processed in isolation
+- **No Analytics Tracking**: No usage analytics sent to external services
+
+### Data Ownership
+
+You maintain complete ownership of all data:
+- **Export Anytime**: Download all your transcripts and audio
+- **Delete on Demand**: Permanent deletion with no recovery
+- **API Access**: Full programmatic access to your data
+- **No Vendor Lock-in**: Standard formats for easy migration
+
+## Processing Transparency
+
+### What Happens to Your Audio
+
+1. **Upload/Stream**: Audio received by your server
+2. **Temporary Storage**: Stored only for processing duration
+3. **Processing**: ML models process audio locally or on Modal
+4. **Results Storage**: Transcripts stored in your database
+5. **Cleanup**: Original audio deleted (unless configured otherwise)
+
+### Local vs Cloud Processing
+
+#### Local Processing
+When configured for local processing:
+- All models run on your hardware
+- No data leaves your infrastructure
+- Complete air-gap capability
+- Higher hardware requirements
+
+#### Modal.com Processing
+When using Modal for GPU acceleration:
+- Audio chunks sent to Modal for processing
+- Processed immediately and deleted
+- No long-term storage on Modal
+- Modal's security: SOC 2 Type II compliant
+
+### Data Retention
+
+Default retention policies:
+- **Public Mode**: 24 hours then automatic deletion
+- **Private Mode**: Configurable (default: indefinite)
+- **Audio Files**: Deleted after processing (configurable)
+- **Transcripts**: Retained based on policy
+
+## Compliance Features
+
+### GDPR Compliance
+
+- **Right to Access**: Export all user data
+- **Right to Deletion**: Permanent data removal
+- **Data Portability**: Standard export formats
+- **Privacy by Default**: Minimal data collection
+
+### HIPAA Considerations
+
+For healthcare deployments:
+- **Self-hosted Option**: Complete infrastructure control
+- **Encryption**: At rest and in transit
+- **Audit Logging**: Complete access trail
+- **Access Controls**: Role-based permissions
+
+### Industry Standards
+
+- **TLS 1.3**: Modern encryption for data in transit
+- **AES-256**: Encryption for data at rest
+- **JWT Tokens**: Secure, stateless authentication
+- **OWASP Guidelines**: Security best practices
+
+## Self-Hosted Deployment
+
+### Complete Independence
+
+Self-hosting provides maximum control:
+- **Your Infrastructure**: Run on your servers
+- **Your Network**: No external connections required
+- **Your Policies**: Implement custom retention
+- **Your Compliance**: Meet specific requirements
+
+### Air-Gap Capability
+
+Reflector can run completely offline:
+1. Download all models during setup
+2. Configure for local processing only
+3. Disable all external integrations
+4. Run in isolated network environment
+
+## Data Flow Control
+
+### Configurable Processing
+
+Control where each step happens:
+
+```yaml
+# All local processing
+TRANSCRIPT_BACKEND=local
+DIARIZATION_BACKEND=local
+TRANSLATION_BACKEND=local
+
+# Hybrid approach
+TRANSCRIPT_BACKEND=modal  # Fast GPU processing
+DIARIZATION_BACKEND=local # Sensitive speaker data
+TRANSLATION_BACKEND=modal  # Non-sensitive translation
+```
+
+### Storage Options
+
+Choose where data is stored:
+- **Local Filesystem**: Complete control
+- **PostgreSQL**: Self-hosted database
+- **S3-Compatible**: MinIO or AWS with encryption
+- **Hybrid**: Different storage for different data types
+
+## Security Architecture
+
+### Defense in Depth
+
+Multiple layers of security:
+1. **Network Security**: Firewalls and VPNs
+2. **Application Security**: Input validation and sanitization
+3. **Data Security**: Encryption and access controls
+4. **Operational Security**: Logging and monitoring
+
+### Zero Trust Principles
+
+- **Verify Everything**: All requests authenticated
+- **Least Privilege**: Minimal permissions granted
+- **Assume Breach**: Design for compromise containment
+- **Encrypt Everything**: No plaintext transmission
+
+## Audit and Compliance
+
+### Audit Logging
+
+Comprehensive logging of:
+- **Access Events**: Who accessed what and when
+- **Processing Events**: What was processed and how
+- **Configuration Changes**: System modifications
+- **Security Events**: Failed authentication attempts
+
+### Compliance Reporting
+
+Generate reports for:
+- **Data Processing**: What data was processed
+- **Data Access**: Who accessed the data
+- **Data Retention**: What was retained or deleted
+- **Security Events**: Security-related incidents
+
+## Best Practices
+
+### For Maximum Privacy
+
+1. **Self-host** all components
+2. **Use local processing** for all models
+3. **Implement short retention** periods
+4. **Encrypt all storage** at rest
+5. **Use VPN** for all connections
+6. **Regular audits** of access logs
+
+### For Balanced Approach
+
+1. **Self-host core services** (database, API)
+2. **Use Modal for processing** (faster, cost-effective)
+3. **Implement encryption** everywhere
+4. **Regular backups** with encryption
+5. **Monitor access** patterns

+title: Authentication Setup
+---
+
+# Authentication Setup
+
+This page covers authentication setup in detail. For the complete deployment guide, see [Deployment Guide](./overview).
+
+Reflector uses [Authentik](https://goauthentik.io/) for OAuth/OIDC authentication. This guide walks you through setting up Authentik and connecting it to Reflector.
+
+The guide simplistically sets Authentic on the same server as Reflector. You can use your own Authentic instance instead.
+
+## Overview
+
+Reflector's authentication flow:
+1. User clicks "Sign In" on frontend
+2. Frontend redirects to Authentik login page
+3. User authenticates with Authentik
+4. Authentik redirects back with OAuth tokens
+5. Frontend stores tokens, backends verify JWT signature
+
+## Option 1: Self-Hosted Authentik (Same Server)
+
+This setup runs Authentik on the same server as Reflector, with Caddy proxying to both.
+
+### Deploy Authentik
+
+```bash
+# Create directory for Authentik
+mkdir -p ~/authentik && cd ~/authentik
+
+# Download docker-compose file
+curl -O https://goauthentik.io/docker-compose.yml
+
+# Generate secrets and bootstrap credentials
+cat > .env << 'EOF'
+PG_PASS=$(openssl rand -base64 36 | tr -d '\n')
+AUTHENTIK_SECRET_KEY=$(openssl rand -base64 60 | tr -d '\n')
+# Privacy-focused choice for self-hosted deployments
+AUTHENTIK_ERROR_REPORTING__ENABLED=false
+AUTHENTIK_BOOTSTRAP_PASSWORD=YourSecurePassword123
+AUTHENTIK_BOOTSTRAP_EMAIL=admin@example.com
+EOF
+
+# Start Authentik
+sudo docker compose up -d
+```
+
+Authentik takes ~2 minutes to run migrations and apply blueprints on first start.
+
+### Connect Authentik to Reflector's Network
+
+If Authentik runs in a separate Docker Compose project, connect it to Reflector's network so Caddy can proxy to it:
+
+```bash
+# Wait for Authentik to be healthy
+# Connect Authentik server to Reflector's network
+sudo docker network connect reflector_default authentik-server-1
+```
+
+**Important:** This step must be repeated if you restart Authentik with `docker compose down`. Add it to your deployment scripts or use `docker compose up -d` (which preserves containers) instead of down/up.
+
+### Add Authentik to Caddy
+
+Uncomment the Authentik section in your `Caddyfile` and set your domain:
+
+```bash
+nano Caddyfile
+```
+
+Uncomment and edit:
+```
+{$AUTHENTIK_DOMAIN:authentik.example.com} {
+    reverse_proxy authentik-server-1:9000
+}
+```
+
+Reload Caddy:
+```bash
+docker compose -f docker-compose.prod.yml exec caddy caddy reload --config /etc/caddy/Caddyfile
+```
+
+### Create OAuth2 Provider in Authentik
+
+**Option A: Automated Setup (Recommended)**
+
+**Location: Reflector server**
+
+Run the setup script from the Reflector repository:
+
+```bash
+ssh user@your-server-ip
+cd ~/reflector
+./scripts/setup-authentik-oauth.sh https://authentik.example.com YourSecurePassword123 https://app.example.com
+```
+
+**Important:** The script must be run from the `~/reflector` directory on your server, as it creates files using relative paths.
+
+The script will output the configuration values to add to your `.env` files. Skip to "Update docker-compose.prod.yml".
+
+**Option B: Manual Setup**
+
+1. **Login to Authentik Admin** at `https://authentik.example.com/`
+   - Username: `akadmin`
+   - Password: The `AUTHENTIK_BOOTSTRAP_PASSWORD` you set in .env
+
+2. **Create OAuth2 Provider:**
+   - Go to **Applications > Providers > Create**
+   - Select **OAuth2/OpenID Provider**
+   - Configure:
+     - **Name**: `Reflector`
+     - **Authorization flow**: `default-provider-authorization-implicit-consent`
+     - **Client type**: `Confidential`
+     - **Client ID**: Note this value (auto-generated)
+     - **Client Secret**: Note this value (auto-generated)
+     - **Redirect URIs**: Add entry with:
+       ```
+       https://app.example.com/api/auth/callback/authentik
+       ```
+   - Scroll down to **Advanced protocol settings**
+   - In **Scopes**, add these three mappings:
+     - `authentik default OAuth Mapping: OpenID 'email'`
+     - `authentik default OAuth Mapping: OpenID 'openid'`
+     - `authentik default OAuth Mapping: OpenID 'profile'`
+   - Click **Finish**
+
+3. **Create Application:**
+   - Go to **Applications > Applications > Create**
+   - Configure:
+     - **Name**: `Reflector`
+     - **Slug**: `reflector` (auto-filled)
+     - **Provider**: Select the `Reflector` provider you just created
+   - Click **Create**
+
+### Get Public Key for JWT Verification
+
+**Location: Reflector server**
+
+Extract the public key from Authentik's JWKS endpoint:
+
+```bash
+mkdir -p ~/reflector/server/reflector/auth/jwt/keys
+curl -s https://authentik.example.com/application/o/reflector/jwks/ | \
+  jq -r '.keys[0].x5c[0]' | base64 -d | openssl x509 -pubkey -noout \
+  > ~/reflector/server/reflector/auth/jwt/keys/authentik_public.pem
+```
+
+### Update docker-compose.prod.yml
+
+**Location: Reflector server**
+
+**Note:** This step is already done in the current `docker-compose.prod.yml`. Verify the volume mounts exist:
+
+```yaml
+server:
+  image: monadicalsas/reflector-backend:latest
+  # ... other config ...
+  volumes:
+    - server_data:/app/data
+    - ./server/reflector/auth/jwt/keys:/app/reflector/auth/jwt/keys:ro
+
+worker:
+  image: monadicalsas/reflector-backend:latest
+  # ... other config ...
+  volumes:
+    - server_data:/app/data
+    - ./server/reflector/auth/jwt/keys:/app/reflector/auth/jwt/keys:ro
+```
+
+### Configure Reflector Backend
+
+**Location: Reflector server**
+
+Update `server/.env`:
+```env
+# Authentication
+AUTH_BACKEND=jwt
+AUTH_JWT_PUBLIC_KEY=authentik_public.pem
+AUTH_JWT_AUDIENCE=<your-client-id>
+CORS_ALLOW_CREDENTIALS=true
+```
+
+Replace `<your-client-id>` with the Client ID from previous steps.
+
+### Configure Reflector Frontend
+
+**Location: Reflector server**
+
+Update `www/.env`:
+```env
+# Authentication
+FEATURE_REQUIRE_LOGIN=true
+
+# Authentik OAuth
+AUTHENTIK_ISSUER=https://authentik.example.com/application/o/reflector
+AUTHENTIK_REFRESH_TOKEN_URL=https://authentik.example.com/application/o/token/
+AUTHENTIK_CLIENT_ID=<your-client-id>
+AUTHENTIK_CLIENT_SECRET=<your-client-secret>
+
+# NextAuth
+NEXTAUTH_SECRET=<generate-with-openssl-rand-hex-32>
+```
+
+### Restart Services
+
+**Location: Reflector server**
+
+```bash
+cd ~/reflector
+sudo docker compose -f docker-compose.prod.yml up -d --force-recreate server worker web
+```
+
+### Verify Authentication
+
+1. Visit `https://app.example.com`
+2. Click "Log in" or navigate to `/api/auth/signin`
+3. Click "Sign in with Authentik"
+4. Login with your Authentik credentials
+5. You should be redirected back and see "Log out" in the header
+
+## Option 2: Disable Authentication
+
+For testing or internal deployments where authentication isn't needed:
+
+**Backend `server/.env`:**
+```env
+AUTH_BACKEND=none
+```
+
+**Frontend `www/.env`:**
+```env
+FEATURE_REQUIRE_LOGIN=false
+```
+
+**Note:** The pre-built Docker images have `FEATURE_REQUIRE_LOGIN=true` baked in. To disable auth, you'll need to rebuild the frontend image with the env var set at build time, or set up Authentik.
+
+## Troubleshooting
+
+### "Invalid redirect URI" error
+- Verify the redirect URI in Authentik matches exactly:
+  ```
+  https://app.example.com/api/auth/callback/authentik
+  ```
+- Check for trailing slashes - they must match exactly
+
+### "Invalid audience" JWT error
+- Ensure `AUTH_JWT_AUDIENCE` in `server/.env` matches the Client ID from Authentik
+- The audience value is the OAuth Client ID, not the issuer URL
+
+### "JWT verification failed" error
+- Verify the public key file is mounted in the container
+- Check `AUTH_JWT_PUBLIC_KEY` points to the correct filename
+- Ensure the key was extracted from the correct provider's JWKS endpoint
+
+### Caddy returns 503 for Authentik
+- Verify Authentik container is connected to Reflector's network:
+  ```bash
+  sudo docker network connect reflector_default authentik-server-1
+  ```
+- Check Authentik is healthy: `cd ~/authentik && sudo docker compose ps`
+
+### Users can't access protected pages
+- Verify `FEATURE_REQUIRE_LOGIN=true` in frontend
+- Check `AUTH_BACKEND=jwt` in backend
+- Verify CORS settings allow credentials
+
+### Token refresh errors
+- Ensure Redis is running (frontend uses Redis for token caching)
+- Verify `KV_URL` is set correctly in frontend env
+- Check `AUTHENTIK_REFRESH_TOKEN_URL` is correct
+
+## API Key Authentication
+
+For programmatic access (scripts, integrations), users can generate API keys:
+
+1. Login to Reflector
+2. Go to Settings > API Keys
+3. Click "Generate New Key"
+4. Use the key in requests:
+   ```bash
+   curl -H "X-API-Key: your-api-key" https://api.example.com/v1/transcripts
+   ```
+
+API keys are stored hashed and can be revoked at any time.

+
+# Daily.co Setup
+
+This page covers Daily.co video platform setup for live meeting rooms. For the complete deployment guide, see [Deployment Guide](./overview).
+
+Daily.co enables live video meetings with automatic recording and transcription.
+
+## What You'll Set Up
+
+```
+User joins meeting → Daily.co video room → Recording to S3 → [Webhook] → Reflector transcribes
+```
+
+## Prerequisites
+
+- [ ] **Daily.co account** - Free tier at https://dashboard.daily.co
+- [ ] **AWS account** - For S3 storage
+- [ ] **Reflector deployed** - Complete steps from [Deployment Guide](./overview)
+
+---
+
+## Create Daily.co Account
+
+1. Visit https://dashboard.daily.co and sign up
+2. Verify your email
+3. Note your subdomain (e.g., `yourname.daily.co` → subdomain is `yourname`)
+
+---
+
+## Get Daily.co API Key
+
+1. In Daily.co dashboard, go to **Developers**
+2. Click **API Keys**
+3. Click **Create API Key**
+4. Copy the key (starts with a long string)
+
+Save this for later.
+
+---
+
+## Create AWS S3 Bucket
+
+Daily.co needs somewhere to store recordings before Reflector processes them.
+
+```bash
+# Choose a unique bucket name
+BUCKET_NAME="reflector-dailyco-yourname" # -yourname is not a requirement, you can name the bucket as you wish
+AWS_REGION="us-east-1"
+
+# Create bucket
+aws s3 mb s3://$BUCKET_NAME --region $AWS_REGION
+
+# Enable versioning (required)
+aws s3api put-bucket-versioning \
+  --bucket $BUCKET_NAME \
+  --versioning-configuration Status=Enabled
+```
+
+---
+
+## Create IAM Role for Daily.co
+
+Daily.co needs permission to write recordings to your S3 bucket.
+
+Follow the guide https://docs.daily.co/guides/products/live-streaming-recording/storing-recordings-in-a-custom-s3-bucket
+
+Save the role ARN - you'll need it soon.
+
+It looks like: `arn:aws:iam::123456789012:role/DailyCo`
+
+Shortly, you'll need to set up a role and give this role your s3 bucket access
+
+No additional setup is required from Daily.co settings website side: the app code takes care of letting Daily know where to save the recordings.
+
+---
+
+## Configure Reflector
+
+**Location: Reflector server**
+
+Add to `server/.env`:
+
+```env
+# Daily.co Configuration
+DEFAULT_VIDEO_PLATFORM=daily
+DAILY_API_KEY=<your-api-key-from-daily-setup>
+DAILY_SUBDOMAIN=<your-subdomain-from-daily-setup>
+
+# S3 Storage for Daily.co recordings
+DAILYCO_STORAGE_AWS_BUCKET_NAME=<your-bucket-from-daily-setup>
+DAILYCO_STORAGE_AWS_REGION=us-east-1
+DAILYCO_STORAGE_AWS_ROLE_ARN=<your-role-arn-from-daily-setup>
+
+# Transcript storage (should already be configured from main setup)
+# TRANSCRIPT_STORAGE_BACKEND=aws
+# TRANSCRIPT_STORAGE_AWS_ACCESS_KEY_ID=<your-key>
+# TRANSCRIPT_STORAGE_AWS_SECRET_ACCESS_KEY=<your-secret>
+# TRANSCRIPT_STORAGE_AWS_BUCKET_NAME=<your-bucket-name>
+# TRANSCRIPT_STORAGE_AWS_REGION=<your-bucket-region>
+```
+
+---
+
+## Restart Services
+
+After changing `.env` files, reload with `up -d`:
+
+```bash
+sudo docker compose -f docker-compose.prod.yml up -d server worker
+```
+
+**Note**: `docker compose up -d` detects env changes and recreates containers automatically.
+
+---
+
+## Test Live Room
+
+1. Visit your Reflector frontend: `https://app.example.com`
+2. Go to **Rooms**
+3. Click **Create Room**
+4. Select **Daily** as the platform
+5. Allow camera/microphone access
+6. You should see Daily.co video interface
+7. Speak for 10-20 seconds
+8. Leave the meeting
+9. Recording should appear in **Transcripts** within 5 minutes (if webhooks aren't set up yet, see [Webhook Configuration](#webhook-configuration-optional) below)
+
+---
+
+## Troubleshooting
+
+### Recording doesn't appear in S3
+
+1. Check Daily.co dashboard → **Logs** for errors
+2. Verify IAM role trust policy has correct Daily.co account ID and your Daily.co subdomain
+3. Verify that the bucket has
+
+### Recording in S3 but not transcribed
+
+1. Check webhook is configured (Reflector should auto-create it)
+2. Check worker logs:
+   ```bash
+   docker compose -f docker-compose.prod.yml logs worker --tail 50
+   ```
+3. Verify `DAILYCO_STORAGE_AWS_*` vars in `server/.env`
+
+### "Access Denied" when Daily.co tries to write to S3
+
+1. Double-check IAM role ARN in Daily.co settings
+2. Verify bucket name matches exactly
+3. Check IAM policy has `s3:PutObject` permission
+
+---
+
+## Webhook Configuration [optional]
+
+`manage_daily_webhook.py` script guides you through creating a webhook for Daily recordings.
+
+The webhook isn't required - polling mechanism is the default and performed automatically.
+
+This guide won't go deep into webhook setup.

+| `postgres` | `postgres:17-alpine` | Primary database |
+| `caddy` | `caddy:2-alpine` | Reverse proxy with auto-SSL |
+
+## Environment Files
+
+Reflector uses two separate environment files:
+
+### Backend (`server/.env`)
+
+Used by: `server`, `worker`, `beat`
+
+Key variables:
+```env
+# Database connection
+DATABASE_URL=postgresql+asyncpg://reflector:reflector@postgres:5432/reflector
+
+# Redis
+REDIS_HOST=redis
+CELERY_BROKER_URL=redis://redis:6379/1
+CELERY_RESULT_BACKEND=redis://redis:6379/1
+
+# API domain and CORS
+BASE_URL=https://api.example.com
+CORS_ORIGIN=https://app.example.com
+
+# Modal GPU processing

+| `postgres_data` | PostgreSQL data |
+| `server_data` | Uploaded files, local storage |
+| `caddy_data` | SSL certificates |
+| `caddy_config` | Caddy configuration |
+
+## Network
+
+All services share the default network. The network is marked `attachable: true` to allow external containers (like Authentik) to join.
+
+## Common Commands
+
+### Start all services
+```bash
+docker compose -f docker-compose.prod.yml up -d
+```
+
+### View logs
+```bash
+# All services
+docker compose -f docker-compose.prod.yml logs -f
+
+# Specific service
+docker compose -f docker-compose.prod.yml logs server --tail 50
+```
+
+### Restart a service
+```bash
+# Quick restart (doesn't reload .env changes)
+docker compose -f docker-compose.prod.yml restart server
+
+# Reload .env and restart
+docker compose -f docker-compose.prod.yml up -d server
+```
+
+### Run database migrations
+```bash
+docker compose -f docker-compose.prod.yml exec server uv run alembic upgrade head
+```
+
+### Access database
+```bash
+docker compose -f docker-compose.prod.yml exec postgres psql -U reflector
+```
+
+### Pull latest images
+```bash
+docker compose -f docker-compose.prod.yml pull
+docker compose -f docker-compose.prod.yml up -d
+```
+
+### Stop all services
+```bash
+docker compose -f docker-compose.prod.yml down
+```
+
+### Full reset (WARNING: deletes data)
+```bash
+docker compose -f docker-compose.prod.yml down -v
+```
+
+## Customization
+
+### Using a different database
+
+To use an external PostgreSQL:
+
+1. Remove `postgres` service from compose file
+2. Update `DATABASE_URL` in `server/.env`:
+   ```env
+   DATABASE_URL=postgresql+asyncpg://user:pass@external-host:5432/reflector
+   ```
+
+### Using external Redis
+
+1. Remove `redis` service from compose file
+2. Update Redis settings in `server/.env`:
+   ```env
+   REDIS_HOST=external-redis-host
+   CELERY_BROKER_URL=redis://external-redis-host:6379/1
+   ```
+
+### Adding Authentik
+
+To add Authentik for authentication, see [Authentication Setup](./auth-setup). Quick steps:
+
+1. Deploy Authentik separately
+2. Connect to Reflector's network:
+   ```bash
+   docker network connect reflector_default authentik-server-1
+   ```
+3. Add to Caddyfile:
+   ```
+   authentik.example.com {
+       reverse_proxy authentik-server-1:9000
+   }
+   ```
+
+## Caddyfile Reference
+
+The Caddyfile supports environment variable substitution:
+
+```
+{$FRONTEND_DOMAIN:app.example.com} {
+    reverse_proxy web:3000
+}
+
+{$API_DOMAIN:api.example.com} {
+    reverse_proxy server:1250
+}
+```
+
+Set `FRONTEND_DOMAIN` and `API_DOMAIN` environment variables, or edit the file directly.
+
+### Reload Caddy after changes
+```bash
+docker compose -f docker-compose.prod.yml exec caddy caddy reload --config /etc/caddy/Caddyfile
+```

+---
+
+# Docs Website Deployment
+
+This guide covers deploying the Reflector documentation website. **This is optional and intended for internal/experimental use only.**
+
+## Overview
+
+The documentation is built using Docusaurus and deployed as a static nginx-served site.
+
+## Prerequisites
+
+- Reflector already deployed (Steps 1-7 from [Deployment Guide](./overview))
+- DNS A record for docs subdomain (e.g., `docs.example.com`)
+
+## Deployment Steps
+
+### Step 1: Pre-fetch OpenAPI Spec
+
+The docs site includes API reference from your running backend. Fetch it before building:
+
+```bash
+cd ~/reflector
+docker compose -f docker-compose.prod.yml exec server curl -s http://localhost:1250/openapi.json > docs/static/openapi.json
+```
+
+This creates `docs/static/openapi.json` (should be ~70KB) which will be copied during Docker build.
+
+**Why not fetch during build?** Docker build containers are network-isolated and can't access the running backend services.
+
+### Step 2: Verify Dockerfile
+
+The Dockerfile is already in `docs/Dockerfile`:
+
+```dockerfile
+FROM node:18-alpine AS builder
+WORKDIR /app
+
+# Copy package files
+COPY package*.json ./
+
+# Inshall dependencies
+RUN npm ci
+
+# Copy source (includes static/openapi.json if pre-fetched)
+COPY . .
+
+# Fix docusaurus config: change onBrokenLinks to 'warn' for Docker build
+RUN sed -i "s/onBrokenLinks: 'throw'/onBrokenLinks: 'warn'/g" docusaurus.config.ts
+
+# Build static site
+RUN npx docusaurus build
+
+FROM nginx:alpine
+COPY --from=builder /app/build /usr/share/nginx/html
+EXPOSE 80
+CMD ["nginx", "-g", "daemon off;"]
+```
+
+### Step 3: Add Docs Service to docker-compose.prod.yml
+
+Add this service to `docker-compose.prod.yml`:
+
+```yaml
+docs:
+  build: ./docs
+  restart: unless-stopped
+  networks:
+    - default
+```
+
+### Step 4: Add Caddy Route
+
+Add to `Caddyfile`:
+
+```
+{$DOCS_DOMAIN:docs.example.com} {
+    reverse_proxy docs:80
+}
+```
+
+### Step 5: Build and Deploy
+
+```bash
+cd ~/reflector
+docker compose -f docker-compose.prod.yml up -d --build docs
+docker compose -f docker-compose.prod.yml exec caddy caddy reload --config /etc/caddy/Caddyfile
+```
+
+### Step 6: Verify
+
+```bash
+# Check container status
+docker compose -f docker-compose.prod.yml ps docs
+# Should show "Up"
+
+# Test URL
+curl -I https://docs.example.com
+# Should return HTTP/2 200
+```
+
+Visit `https://docs.example.com` in your browser
+
+## Updating Documentation
+
+When docs are updated:
+
+```bash
+cd ~/reflector
+git pull
+
+# Refresh OpenAPI spec from backend
+docker compose -f docker-compose.prod.yml exec server curl -s http://localhost:1250/openapi.json > docs/static/openapi.json
+
+# Rebuild docs
+docker compose -f docker-compose.prod.yml up -d --build docs
+```
+
+## Troubleshooting
+
+### Missing openapi.json during build
+- Make sure you ran the pre-fetch step first (Step 1)
+- Verify `docs/static/openapi.json` exists and is ~70KB
+- Re-run: `docker compose exec server curl -s http://localhost:1250/openapi.json > docs/static/openapi.json`
+
+### Build fails with "Docusaurus found broken links"
+- This happens if `onBrokenLinks: 'throw'` is set in docusaurus.config.ts
+- Solution is already in Dockerfile: uses `sed` to change to `'warn'` during build
+
+### 404 on all pages
+- Docusaurus baseUrl might be wrong - should be `/` for custom domain
+- Check `docs/docusaurus.config.ts`: `baseUrl: '/'`
+
+### Docs not updating after rebuild
+- Force rebuild: `docker compose -f docker-compose.prod.yml build --no-cache docs`
+- Then: `docker compose -f docker-compose.prod.yml up -d docs`

+title: Modal.com Setup
+---
+
+# Modal.com Setup
+
+This page covers Modal.com GPU setup in detail. For the complete deployment guide, see [Deployment Guide](./overview).
+
+Reflector uses [Modal.com](https://modal.com) for GPU-accelerated audio processing. This guide walks you through deploying the required GPU functions.
+
+## What is Modal.com?
+
+Modal is a serverless GPU platform. You deploy Python code that runs on their GPUs, and pay only for actual compute time. Reflector uses Modal for:
+
+- **Transcription**: Whisper model for speech-to-text
+- **Diarization**: Pyannote model for speaker identification
+
+## Prerequisites
+
+1. **Modal.com account** - Sign up at https://modal.com (free tier available)
+2. **HuggingFace account** - Required for Pyannote diarization models:
+   - Create account at https://huggingface.co
+   - Accept **both** Pyannote licenses:
+     - https://huggingface.co/pyannote/speaker-diarization-3.1
+     - https://huggingface.co/pyannote/segmentation-3.0
+   - Generate access token at https://huggingface.co/settings/tokens
+
+## Deployment
+
+**Location: YOUR LOCAL COMPUTER (laptop/desktop)**
+
+Modal CLI requires browser authentication, so this must run on a machine with a browser - not on a headless server.
+
+### Install Modal CLI
+
+```bash
+pip install modal
+```
+
+### Authenticate with Modal
+
+```bash
+modal setup
+```
+
+This opens your browser for authentication. Complete the login flow.
+
+### Clone Repository and Deploy
+
+```bash
+git clone https://github.com/monadical-sas/reflector.git
+cd reflector/gpu/modal_deployments
+./deploy-all.sh --hf-token YOUR_HUGGINGFACE_TOKEN
+```
+
+Or run interactively (script will prompt for token):
+```bash
+./deploy-all.sh
+```
+
+### What the Script Does
+
+1. **Prompts for HuggingFace token** - Needed to download the Pyannote diarization model
+2. **Generates API key** - Creates a secure random key for authenticating requests to GPU functions
+3. **Creates Modal secrets**:
+   - `hf_token` - Your HuggingFace token
+   - `reflector-gpu` - The generated API key
+4. **Deploys GPU functions** - Transcriber (Whisper) and Diarizer (Pyannote)
+5. **Outputs configuration** - Prints URLs and API key to console
+
+### Example Output
+
+```

+
+Copy these values to your server's server/.env file:
+
+# --- Modal GPU Configuration ---
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=https://yourname--reflector-transcriber-web.modal.run
+TRANSCRIPT_MODAL_API_KEY=abc123...
+
+DIARIZATION_BACKEND=modal
+DIARIZATION_URL=https://yourname--reflector-diarizer-web.modal.run
+DIARIZATION_MODAL_API_KEY=abc123...
+# --- End Modal Configuration ---
+```
+
+Copy the output and paste it into your `server/.env` file on your server.
+
+## Costs
+
+Modal charges based on GPU compute time:
+- Functions scale to zero when not in use (no cost when idle)
+- You only pay for actual processing time
+- Free tier includes $30/month of credits
+
+Typical costs for audio processing:
+- Transcription: ~$0.01-0.05 per minute of audio
+- Diarization: ~$0.02-0.10 per minute of audio
+
+## Troubleshooting
+
+### "Modal CLI not installed"
+```bash
+pip install modal
+```
+
+### "Not authenticated with Modal"
+```bash
+modal setup
+# Complete browser authentication
+```
+
+### "Failed to create secret hf_token"
+- Verify your HuggingFace token is valid
+- Ensure you've accepted the Pyannote license
+- Token needs `read` permission
+
+### Deployment fails
+Check the Modal dashboard for detailed error logs:
+- Visit https://modal.com/apps
+- Click on the failed function
+- View build and runtime logs
+
+### Re-running deployment
+The script is safe to re-run. It will:
+- Update existing secrets if they exist
+- Redeploy functions with latest code
+- Output new configuration (API key stays the same if secret exists)
+
+## Manual Deployment (Advanced)
+
+If you prefer to deploy functions individually:
+
+```bash
+cd gpu/modal_deployments
+
+# Create secrets manually
+modal secret create hf_token HF_TOKEN=your-hf-token
+modal secret create reflector-gpu REFLECTOR_GPU_APIKEY=$(openssl rand -hex 32)
+
+# Deploy each function
+modal deploy reflector_transcriber.py
+modal deploy reflector_diarizer.py
+```
+
+## Monitoring
+
+View your deployed functions and their usage:
+- **Modal Dashboard**: https://modal.com/apps
+- **Function logs**: Click on any function to view logs
+- **Usage**: View compute time and costs in the dashboard

+
+## Configure DNS
+
+```
+Type: A    Name: app    Value: <your-server-ip>
+Type: A    Name: api    Value: <your-server-ip>
+```
+
+---
+
+## Deploy GPU Processing
+
+Reflector requires GPU processing for transcription and speaker diarization. Choose one option:
+
+| | **Modal.com (Cloud)** | **Self-Hosted GPU** |
+|---|---|---|
+| **Best for** | No GPU hardware, zero maintenance | Own GPU server, full control |
+| **Pricing** | Pay-per-use | Fixed infrastructure cost |
+
+### Option A: Modal.com (Serverless Cloud GPU)
+
+#### Accept HuggingFace Licenses
+
+Visit both pages and click "Accept":
+- https://huggingface.co/pyannote/speaker-diarization-3.1
+- https://huggingface.co/pyannote/segmentation-3.0
+
+Generate a token at https://huggingface.co/settings/tokens
+
+#### Deploy to Modal
+
+There's an install script to help with this setup. It's using modal API to set all necessary moving parts.
+
+As an alternative, all those operations that script does could be performed in modal settings in modal UI.
+
+```bash
+pip install modal
+modal setup  # opens browser for authentication
+
+git clone https://github.com/monadical-sas/reflector.git
+cd reflector/gpu/modal_deployments
+./deploy-all.sh --hf-token YOUR_HUGGINGFACE_TOKEN
+```
+
+**Save the output** - copy the configuration block, you'll need it soon.
+
+See [Modal Setup](./modal-setup) for troubleshooting and details.
+
+### Option B: Self-Hosted GPU
+
+**Location: YOUR GPU SERVER**
+
+Requires: NVIDIA GPU with 8GB+ VRAM, Ubuntu 22.04+, 40-50GB disk (Docker) or 25-30GB (Systemd).
+
+See [Self-Hosted GPU Setup](./self-hosted-gpu-setup) for complete instructions. Quick summary:
+
+1. Install NVIDIA drivers and Docker (or uv for systemd)
+2. Clone repository: `git clone https://github.com/monadical-sas/reflector.git`
+3. Configure `.env` with HuggingFace token
+4. Start service (Docker compose or systemd)
+5. Set up Caddy reverse proxy for HTTPS
+
+**Save your API key and HTTPS URL** - you'll need them soon.
+
+---
+
+## Prepare Server
+
+**Location: dedicated reflector server**
+
+### Install Docker
+
+```bash
+ssh user@your-server-ip
+
+curl -fsSL https://get.docker.com | sh
+sudo usermod -aG docker $USER
+
+# Log out and back in for group changes
+exit
+ssh user@your-server-ip
+
+docker --version  # verify
+```
+
+### Firewall
+
+Ensure ports 80 (HTTP) and 443 (HTTPS) are open for inbound traffic. The method varies by cloud provider and OS configuration.
+
+### Clone Repository
+
+The Docker images contain all application code. You clone the repository for configuration files and the compose definition:
+
+```bash
+git clone https://github.com/monadical-sas/reflector.git
+cd reflector
+```
+
+---
+
+## Create S3 Bucket for Transcript Storage
+
+Reflector requires AWS S3 to store audio files during processing.
+
+### Create Bucket
+
+```bash
+# Choose a unique bucket name
+BUCKET_NAME="reflector-transcripts-yourname"
+AWS_REGION="us-east-1"
+
+# Create bucket
+aws s3 mb s3://$BUCKET_NAME --region $AWS_REGION
+```
+
+### Create IAM User
+
+Create an IAM user with S3 access for Reflector:
+
+1. Go to AWS IAM Console → Users → Create User
+2. Name: `reflector-transcripts`
+3. Attach policy: `AmazonS3FullAccess` (or create a custom policy for just your bucket)
+4. Create access key (Access key ID + Secret access key)
+
+Save these credentials - you'll need them in the next step.
+
+---
+
+## Configure Environment
+
+Reflector has two env files:
+- `server/.env` - Backend configuration
+- `www/.env` - Frontend configuration
+
+### Backend Configuration
+
+```bash
+cp server/.env.example server/.env
+nano server/.env
+```
+
+**Required settings:**
+```env
+# Database (defaults work with docker-compose.prod.yml)
+DATABASE_URL=postgresql+asyncpg://reflector:reflector@postgres:5432/reflector
+
+# Redis
+REDIS_HOST=redis
+CELERY_BROKER_URL=redis://redis:6379/1
+CELERY_RESULT_BACKEND=redis://redis:6379/1
+
+# Your domains
+BASE_URL=https://api.example.com
+CORS_ORIGIN=https://app.example.com
+CORS_ALLOW_CREDENTIALS=true
+
+# Secret key - generate with: openssl rand -hex 32
+SECRET_KEY=<your-generated-secret>
+
+# GPU Processing - choose ONE option:
+
+# Option A: Modal.com (paste from deploy-all.sh output)
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=https://yourname--reflector-transcriber-web.modal.run
+TRANSCRIPT_MODAL_API_KEY=<from-deploy-all.sh-output>
+DIARIZATION_BACKEND=modal
+DIARIZATION_URL=https://yourname--reflector-diarizer-web.modal.run
+DIARIZATION_MODAL_API_KEY=<from-deploy-all.sh-output>
+
+# Option B: Self-hosted GPU (use your GPU server URL and API key)
+# TRANSCRIPT_BACKEND=modal
+# TRANSCRIPT_URL=https://gpu.example.com
+# TRANSCRIPT_MODAL_API_KEY=<your-generated-api-key>
+# DIARIZATION_BACKEND=modal
+# DIARIZATION_URL=https://gpu.example.com
+# DIARIZATION_MODAL_API_KEY=<your-generated-api-key>
+
+# Storage - where to store audio files and transcripts (requires AWS S3)
+TRANSCRIPT_STORAGE_BACKEND=aws
+TRANSCRIPT_STORAGE_AWS_ACCESS_KEY_ID=your-aws-access-key
+TRANSCRIPT_STORAGE_AWS_SECRET_ACCESS_KEY=your-aws-secret-key
+TRANSCRIPT_STORAGE_AWS_BUCKET_NAME=reflector-media
+TRANSCRIPT_STORAGE_AWS_REGION=us-east-1
+
+# LLM - for generating titles, summaries, and topics
+LLM_API_KEY=sk-your-openai-api-key
+LLM_MODEL=gpt-4o-mini
+# LLM_URL=https://api.openai.com/v1  # Optional: custom endpoint (vLLM, LiteLLM, Ollama, etc.)
+
+# Auth - disable for initial setup (see a dedicated step for authentication)
+AUTH_BACKEND=none
+```
+
+### Frontend Configuration
+
+```bash
+cp www/.env.example www/.env
+nano www/.env
+```
+
+**Required settings:**
+```env
+# Your domains
+SITE_URL=https://app.example.com
+API_URL=https://api.example.com
+WEBSOCKET_URL=wss://api.example.com
+SERVER_API_URL=http://server:1250
+
+# NextAuth
+NEXTAUTH_URL=https://app.example.com
+NEXTAUTH_SECRET=<generate-with-openssl-rand-hex-32>
+
+# Disable login requirement for initial setup
+FEATURE_REQUIRE_LOGIN=false
+```
+
+---
+
+## Configure Caddy
+
+```bash
+cp Caddyfile.example Caddyfile
+nano Caddyfile
+```
+
+Replace `example.com` with your domains. The `{$VAR:default}` syntax uses Caddy's env var substitution - you can either edit the file directly or set `FRONTEND_DOMAIN` and `API_DOMAIN` environment variables.
+
+```
+{$FRONTEND_DOMAIN:app.example.com} {
+    reverse_proxy web:3000
+}
+
+{$API_DOMAIN:api.example.com} {
+    reverse_proxy server:1250
+}
+```
+
+---
+
+## Start Services
+
+```bash
+docker compose -f docker-compose.prod.yml up -d
+```
+
+Wait for PostgreSQL to be ready, then run migrations:
+
+```bash
+# Wait for postgres to be healthy (may take 30-60 seconds on first run)
+docker compose -f docker-compose.prod.yml exec postgres pg_isready -U reflector
+
+# Run database migrations
+docker compose -f docker-compose.prod.yml exec server uv run alembic upgrade head
+```
+
+---
+
+## Verify Deployment
+
+### Check services
+```bash
+docker compose -f docker-compose.prod.yml ps
+# All should show "Up"
+```
+
+### Test API
+```bash
+curl https://api.example.com/health
+# Should return: {"status":"healthy"}
+```
+
+### Test Frontend
+- Visit https://app.example.com
+- You should see the Reflector interface
+- Try uploading an audio file to test transcription
+
+---
+
+## Enable Authentication (Required for Live Rooms)
+
+By default, Reflector is open (no login required). **Authentication is required if you want to use Live Meeting Rooms.**
+
+See [Authentication Setup](./auth-setup) for full Authentik OAuth configuration.
+
+Quick summary:
+1. Deploy Authentik on your server
+2. Create OAuth provider in Authentik
+3. Extract public key for JWT verification
+4. Update `server/.env`: `AUTH_BACKEND=jwt` + `AUTH_JWT_AUDIENCE`
+5. Update `www/.env`: `FEATURE_REQUIRE_LOGIN=true` + Authentik credentials
+6. Mount JWT keys volume and restart services
+
+---
+
+## Enable Live Meeting Rooms
+
+**Requires: Authentication Step**
+
+Live rooms require Daily.co and AWS S3. See [Daily.co Setup](./daily-setup) for complete S3/IAM configuration instructions.
+
+Note that Reflector also supports Whereby as a call provider - this doc doesn't cover its setup yet.
+
+Quick config - Add to `server/.env`:
+
+```env
+DEFAULT_VIDEO_PLATFORM=daily
+DAILY_API_KEY=<from-daily.co-dashboard>
+DAILY_SUBDOMAIN=<your-daily-subdomain>
+
+# S3 for recording storage
+DAILYCO_STORAGE_AWS_BUCKET_NAME=<your-bucket>
+DAILYCO_STORAGE_AWS_REGION=us-east-1
+DAILYCO_STORAGE_AWS_ROLE_ARN=<arn:aws:iam::ACCOUNT:role/DailyCo>
+```
+
+Reload env and restart:
+```bash
+docker compose -f docker-compose.prod.yml up -d server worker
+```
+
+---
+
+## Troubleshooting
+
+### Check logs for errors
+```bash
+docker compose -f docker-compose.prod.yml logs server --tail 20
+docker compose -f docker-compose.prod.yml logs worker --tail 20
+```
+
+### Services won't start
+```bash
+docker compose -f docker-compose.prod.yml logs
+```
+
+### CORS errors in browser
+- Verify `CORS_ORIGIN` in `server/.env` matches your frontend domain exactly (including `https://`)
+- Reload env: `docker compose -f docker-compose.prod.yml up -d server`
+
+### SSL certificate errors
+- Caddy auto-provisions Let's Encrypt certificates
+- Ensure ports 80 and 443 are open
+- Check: `docker compose -f docker-compose.prod.yml logs caddy`
+
+### Transcription not working
+- Check Modal dashboard: https://modal.com/apps
+- Verify URLs in `server/.env` match deployed functions
+- Check worker logs: `docker compose -f docker-compose.prod.yml logs worker`
+
+### "Login required" but auth not configured
+- Set `FEATURE_REQUIRE_LOGIN=false` in `www/.env`
+- Rebuild frontend: `docker compose -f docker-compose.prod.yml up -d --force-recreate web`

+
+# Self-Hosted GPU Setup
+
+This guide covers deploying Reflector's GPU processing on your own server instead of Modal.com. For the complete deployment guide, see [Deployment Guide](./overview).
+
+## When to Use Self-Hosted GPU
+
+**Choose self-hosted GPU if you:**
+- Have GPU hardware available (NVIDIA required)
+- Want full control over processing
+- Prefer fixed infrastructure costs over pay-per-use
+- Have privacy or data locality requirements
+- Need to process audio without external API calls
+
+**Choose Modal.com instead if you:**
+- Don't have GPU hardware
+- Want zero infrastructure management
+- Prefer pay-per-use pricing
+- Need instant scaling for variable workloads
+
+See [Modal.com Setup](./modal-setup) for cloud GPU deployment.
+
+## What Gets Deployed
+
+The self-hosted GPU service provides the same API endpoints as Modal:
+- `POST /v1/audio/transcriptions` - Whisper transcription
+- `POST /diarize` - Pyannote speaker diarization
+
+Your main Reflector server connects to this service exactly like it connects to Modal - only the URL changes.
+
+## Prerequisites
+
+### Hardware
+- **GPU**: NVIDIA GPU with 8GB+ VRAM (tested on Tesla T4 with 15GB)
+- **CPU**: 4+ cores recommended
+- **RAM**: 8GB minimum, 16GB recommended
+- **Disk**:
+  - Docker method: 40-50GB minimum
+  - Systemd method: 25-30GB minimum
+
+### Software
+- Public IP address
+- Domain name with DNS A record pointing to server
+
+### Accounts
+- **HuggingFace account** with accepted Pyannote licenses:
+  - https://huggingface.co/pyannote/speaker-diarization-3.1
+  - https://huggingface.co/pyannote/segmentation-3.0
+- **HuggingFace access token** from https://huggingface.co/settings/tokens
+
+## Choose Deployment Method
+
+---
+
+## Docker Deployment
+
+### Step 1: Install NVIDIA Driver
+
+```bash
+sudo apt update
+sudo apt install -y nvidia-driver-535
+
+# Load kernel modules
+sudo modprobe nvidia
+
+# Verify installation
+nvidia-smi
+```
+
+Expected output: GPU details with driver version and CUDA version.
+
+### Step 2: Install Docker
+
+```bash
+curl -fsSL https://get.docker.com | sudo sh
+sudo usermod -aG docker $USER
+
+# Log out and back in for group changes
+exit
+# SSH back in
+```
+
+### Step 3: Install NVIDIA Container Toolkit
+
+```bash
+# Add NVIDIA repository
+curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | \
+  sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg
+
+curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
+  sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
+  sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
+
+# Install toolkit
+sudo apt-get update
+sudo apt-get install -y nvidia-container-toolkit
+
+# Configure Docker runtime
+sudo nvidia-ctk runtime configure --runtime=docker
+sudo systemctl restart docker
+```
+
+### Step 4: Clone Repository and Configure
+
+```bash
+git clone https://github.com/monadical-sas/reflector.git
+cd reflector/gpu/self_hosted
+
+# Create environment file
+cat > .env << EOF
+REFLECTOR_GPU_APIKEY=$(openssl rand -hex 16)
+HF_TOKEN=your_huggingface_token_here
+EOF
+
+# Note the generated API key - you'll need it for main server config
+cat .env
+```
+
+### Step 5: Create Docker Compose File
+
+```bash
+cat > compose.yml << 'EOF'
+services:
+  reflector_gpu:
+    build:
+      context: .
+    ports:
+      - "8000:8000"
+    env_file:
+      - .env
+    volumes:
+      - ./cache:/root/.cache
+    deploy:
+      resources:
+        reservations:
+          devices:
+            - driver: nvidia
+              count: all
+              capabilities: [gpu]
+    restart: unless-stopped
+EOF
+```
+
+### Step 6: Build and Start
+
+```bash
+# Build image (takes ~5 minutes, downloads ~10GB)
+sudo docker compose build
+
+# Start service
+sudo docker compose up -d
+
+# Wait for startup and verify
+sleep 30
+sudo docker compose logs
+```
+
+Look for: `INFO: Application startup complete. Uvicorn running on http://0.0.0.0:8000`
+
+### Step 7: Verify GPU Access
+
+```bash
+# Check GPU is accessible from container
+sudo docker exec $(sudo docker ps -q) nvidia-smi
+```
+
+Should show GPU with ~3GB VRAM used (models loaded).
+
+---
+
+## Systemd Deployment
+
+### Step 1: Install NVIDIA Driver
+
+```bash
+sudo apt update
+sudo apt install -y nvidia-driver-535
+
+# Load kernel modules
+sudo modprobe nvidia
+
+# Verify installation
+nvidia-smi
+```
+
+### Step 2: Install Dependencies
+
+```bash
+# Install ffmpeg
+sudo apt install -y ffmpeg
+
+# Install uv package manager
+curl -LsSf https://astral.sh/uv/install.sh | sh
+source ~/.local/bin/env
+
+# Clone repository
+git clone https://github.com/monadical-sas/reflector.git
+cd reflector/gpu/self_hosted
+```
+
+### Step 3: Configure Environment
+
+```bash
+# Create environment file
+cat > .env << EOF
+REFLECTOR_GPU_APIKEY=$(openssl rand -hex 16)
+HF_TOKEN=your_huggingface_token_here

+
+# Note the generated API key
+cat .env
+```
+
+### Step 4: Install Python Packages
+
+```bash
+# Install dependencies (~3GB download)
+uv sync
+```
+
+### Step 5: Create Systemd Service
+
+```bash
+# Generate library paths for NVIDIA packages
+export NVIDIA_LIBS=$(find ~/reflector/gpu/self_hosted/.venv/lib/python3.12/site-packages/nvidia -name lib -type d | tr '\n' ':')
+
+# Load environment variables
+source ~/reflector/gpu/self_hosted/.env
+
+# Create service file
+sudo tee /etc/systemd/system/reflector-gpu.service << EOFSVC

+
+```bash
+# Check status
+sudo systemctl status reflector-gpu
+
+# View logs
+sudo journalctl -u reflector-gpu -f
+```
+
+Look for: `INFO: Application startup complete.`
+
+---
+
+## Configure HTTPS with Caddy
+
+Both deployment methods need HTTPS for production. Caddy handles SSL automatically.
+
+### Install Caddy
+
+```bash
+sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
+
+curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | \
+  sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
+
+curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | \
+  sudo tee /etc/apt/sources.list.d/caddy-stable.list
+
+sudo apt update
+sudo apt install -y caddy
+```
+
+### Configure Reverse Proxy
+
+```bash
+sudo tee /etc/caddy/Caddyfile << 'EOF'
+gpu.example.com {
+    reverse_proxy localhost:8000
+}
+EOF
+
+# Reload Caddy (auto-provisions SSL certificate)
+sudo systemctl reload caddy
+```
+
+Replace `gpu.example.com` with your domain.
+
+### Verify HTTPS
+
+```bash
+curl -I https://gpu.example.com/docs
+# Should return HTTP/2 200
+```
+
+---
+
+## Configure Main Reflector Server
+
+On your main Reflector server, update `server/.env`:
+
+```env
+# GPU Processing - Self-hosted
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=https://gpu.example.com
+TRANSCRIPT_MODAL_API_KEY=<your-generated-api-key>
+
+DIARIZATION_BACKEND=modal
+DIARIZATION_URL=https://gpu.example.com
+DIARIZATION_MODAL_API_KEY=<your-generated-api-key>
+```
+
+**Note:** The backend type is `modal` because the self-hosted GPU service implements the same API contract as Modal.com. This allows you to switch between cloud and self-hosted GPU processing by only changing the URL and API key.
+
+Restart services to apply:
+
+```bash
+docker compose -f docker-compose.prod.yml restart server worker
+```
+
+---
+
+## Service Management
+
+All commands in this section assume you're in `~/reflector/gpu/self_hosted/`.
+
+### Docker
+
+```bash
+# View logs
+sudo docker compose logs -f
+
+# Restart service
+sudo docker compose restart
+
+# Stop service
+sudo docker compose down
+
+# Check status
+sudo docker compose ps
+```
+
+### Systemd
+
+```bash
+# View logs
+sudo journalctl -u reflector-gpu -f
+
+# Restart service
+sudo systemctl restart reflector-gpu
+
+# Stop service
+sudo systemctl stop reflector-gpu
+
+# Check status
+sudo systemctl status reflector-gpu
+```
+
+### Monitor GPU
+
+```bash
+# Check GPU usage
+nvidia-smi
+
+# Watch in real-time
+watch -n 1 nvidia-smi
+```
+
+**Typical GPU memory usage:**
+- Idle (models loaded): ~3GB VRAM
+- During transcription: ~4-5GB VRAM
+
+---
+
+## Troubleshooting
+
+### nvidia-smi fails after driver install
+
+```bash
+# Manually load kernel modules
+sudo modprobe nvidia
+nvidia-smi
+```
+
+### Service fails with "Could not download pyannote pipeline"
+
+1. Verify HF_TOKEN is valid: `echo $HF_TOKEN`
+2. Check model access at https://huggingface.co/pyannote/speaker-diarization-3.1
+3. Regenerate service/compose with correct token
+4. Restart service
+
+### cuDNN library loading errors (Systemd only)
+
+Symptom: `Unable to load libcudnn_cnn.so`
+
+Regenerate the systemd service file - the `LD_LIBRARY_PATH` must include all NVIDIA package directories.
+
+### Cannot connect to HTTPS endpoint
+
+1. Verify DNS resolves: `dig +short gpu.example.com`
+2. Check firewall: `sudo ufw status` (ports 80, 443 must be open)
+3. Check Caddy: `sudo systemctl status caddy`
+4. View Caddy logs: `sudo journalctl -u caddy -n 50`
+
+### SSL certificate not provisioning
+
+Requirements for Let's Encrypt:
+- Ports 80 and 443 publicly accessible
+- DNS resolves to server's public IP
+- Valid domain (not localhost or private IP)
+
+### Docker container won't start
+
+```bash
+# Check logs
+sudo docker compose logs
+
+# Common issues:
+# - Port 8000 already in use
+# - GPU not accessible (nvidia-ctk not configured)
+# - Missing .env file
+```
+
+---
+
+## Updating
+
+### Docker
+
+```bash
+cd ~/reflector/gpu/self_hosted
+git pull
+sudo docker compose build
+sudo docker compose up -d
+```
+
+### Systemd
+
+```bash
+cd ~/reflector/gpu/self_hosted
+git pull
+uv sync
+sudo systemctl restart reflector-gpu
+```

+
+# Welcome to Reflector
+
+Reflector is a privacy-focused, self-hosted AI-powered audio transcription and meeting analysis platform that provides real-time transcription, speaker diarization, translation, and summarization for audio content and live meetings. With complete control over your data and infrastructure, you can run models on your own hardware (roadmap - currently supports Modal.com for GPU processing).
+
+## What is Reflector?
+
+Reflector is a web application that utilizes AI to process audio content, providing:
+

+title: File Processing Pipeline
+---
+
+# File Processing Pipeline
+
+The file processing pipeline handles uploaded audio files, optimizing for accuracy and throughput.
+
+## Pipeline Stages
+
+### 1. Input Stage
+
+**Accepted Formats:**
+- MP3 (most common)
+- WAV (uncompressed)
+- M4A (Apple format)
+- WebM (browser recordings)
+- MP4 (video with audio track)
+
+**File Validation:**
+- Maximum size: 2GB (configurable)
+- Minimum duration: 5 seconds
+- Maximum duration: 6 hours
+- Sample rate: Any (will be resampled)
+
+### 2. Pre-processing
+
+**Audio Normalization:**
+```yaml
+# Convert to standard format
+- Sample rate: 16kHz (Whisper requirement)
+- Channels: Mono
+- Bit depth: 16-bit
+- Format: WAV
+```
+
+**Noise Reduction (Optional):**
+- Background noise removal
+- Echo cancellation
+- High-pass filter for rumble
+
+### 3. Chunking Strategy
+
+**Default Configuration:**
+```yaml
+chunk_size: 30  # seconds
+overlap: 1      # seconds
+max_parallel: 10
+silence_detection: true
+```
+
+**Chunking with Silence Detection:**
+- Detects silence periods
+- Attempts to break at natural pauses
+- Maintains context with overlap
+- Preserves sentence boundaries
+
+**Chunk Metadata:**
+```json
+{
+  "chunk_id": "chunk_001",
+  "start_time": 0.0,
+  "end_time": 30.0,
+  "duration": 30.0,
+  "has_speech": true,
+  "audio_hash": "sha256:..."
+}
+```
+
+### 4. Transcription Processing
+
+**Whisper Models:**
+
+| Model | Size | Speed | Accuracy | Use Case |
+|-------|------|-------|----------|----------|
+| tiny | 39M | Very Fast | 85% | Quick drafts |
+| base | 74M | Fast | 89% | Good balance |
+| small | 244M | Medium | 91% | Better accuracy |
+| medium | 769M | Slow | 93% | High quality |
+| large-v3 | 1550M | Very Slow | 96% | Best quality |
+
+**Processing Configuration:**
+```python
+transcription_config = {
+    "model": "whisper-base",
+    "language": "auto",  # or specify: "en", "es", etc.
+    "task": "transcribe",  # or "translate"
+    "temperature": 0,  # deterministic
+    "compression_ratio_threshold": 2.4,
+    "no_speech_threshold": 0.6,
+    "condition_on_previous_text": True,
+    "initial_prompt": None,  # optional context
+}
+```
+
+**Parallel Processing:**
+- Each chunk processed independently
+- GPU batching for efficiency
+- Automatic load balancing
+- Failure isolation
+
+### 5. Diarization (Speaker Identification)
+
+**Pyannote 3.1 Pipeline:**
+
+1. **Voice Activity Detection (VAD)**
+   - Identifies speech segments
+   - Filters out silence and noise
+   - Precision: 95%+
+
+2. **Speaker Embedding**
+   - Extracts voice characteristics
+   - 256-dimensional vectors
+   - Speaker-invariant features
+
+3. **Clustering**
+   - Groups similar voice embeddings
+   - Agglomerative clustering
+   - Automatic speaker count detection
+
+4. **Segmentation**
+   - Assigns speaker labels to time segments
+   - Handles overlapping speech
+   - Minimum segment duration: 0.5s
+
+**Configuration:**
+```python
+diarization_config = {
+    "min_speakers": 1,
+    "max_speakers": 10,
+    "min_duration": 0.5,
+    "clustering": "AgglomerativeClustering",
+    "embedding_model": "speechbrain/spkrec-ecapa-voxceleb",
+}
+```
+
+### 6. Alignment & Merging
+
+**Chunk Assembly:**
+```python
+# Merge overlapping segments
+for chunk in chunks:
+    # Remove overlap duplicates
+    if chunk.start < previous.end:
+        chunk.text = resolve_overlap(previous, chunk)
+
+    # Maintain timeline
+    merged_transcript.append(chunk)
+```
+
+**Speaker Alignment:**
+- Map diarization timeline to transcript
+- Resolve speaker changes mid-sentence
+- Handle multiple speakers per segment
+
+**Quality Checks:**
+- Timeline consistency
+- No gaps in transcript
+- Speaker label continuity
+- Confidence score validation
+
+### 7. Post-processing Chain
+
+**Text Formatting:**
+- Sentence capitalization
+- Punctuation restoration
+- Number formatting
+- Acronym detection
+
+**Translation (Optional):**
+```python
+translation_config = {
+    "model": "facebook/seamless-m4t-medium",
+    "source_lang": "auto",
+    "target_langs": ["es", "fr", "de"],
+    "preserve_formatting": True
+}
+```
+
+**Topic Detection:**
+- LLM-based analysis
+- Extract 3-5 key topics
+- Keyword extraction
+- Entity recognition
+
+**Summarization:**
+```python
+summary_config = {
+    "model": "openai-compatible",
+    "max_length": 500,
+    "style": "bullets",  # or "paragraph"
+    "include_action_items": True,
+    "include_decisions": True
+}
+```
+
+### 8. Storage & Delivery
+
+**Database Storage:**
+```sql
+-- Main transcript record
+INSERT INTO transcripts (
+    id, title, duration, language,
+    transcript_text, transcript_json,
+    speakers, topics, summary,
+    created_at, processing_time
+) VALUES (...);
+
+-- Processing metadata
+INSERT INTO processing_metadata (
+    transcript_id, model_versions,
+    chunk_count, total_chunks,
+    error_count, warnings
+) VALUES (...);
+```
+
+**File Storage:**
+- Original audio: S3 (optional)
+- Processed chunks: Temporary (24h)
+- Transcript exports: JSON, SRT, VTT, TXT
+
+**Notification:**
+```json
+{
+  "type": "webhook",
+  "url": "https://your-app.com/webhook",
+  "payload": {
+    "transcript_id": "...",
+    "status": "completed",
+    "duration": 3600,
+    "processing_time": 180
+  }
+}
+```
+
+## Processing Times
+
+**Estimated times for 1 hour of audio:**
+
+| Component | Fast Mode | Balanced | High Quality |
+|-----------|-----------|----------|--------------|
+| Pre-processing | 10s | 10s | 10s |
+| Transcription | 60s | 180s | 600s |
+| Diarization | 30s | 60s | 120s |
+| Post-processing | 20s | 30s | 60s |
+| **Total** | **2 min** | **5 min** | **13 min** |
+
+## Error Handling
+
+### Retry Strategy
+
+```python
+@celery.task(
+    bind=True,
+    max_retries=3,
+    default_retry_delay=60,
+    retry_backoff=True
+)
+def process_chunk(self, chunk_id):
+    try:
+        # Process chunk
+        result = transcribe(chunk_id)
+    except Exception as exc:
+        # Exponential backoff
+        raise self.retry(exc=exc)
+```
+
+### Partial Recovery
+
+- Continue with successful chunks
+- Mark failed chunks in output
+- Provide partial transcript
+- Report processing issues
+
+### Fallback Options
+
+1. **Model Fallback:**
+   - If large model fails, try medium
+   - If GPU fails, try CPU
+   - If Modal fails, try local
+
+2. **Quality Degradation:**
+   - Reduce chunk size
+   - Disable post-processing
+   - Skip diarization if needed
+
+## Optimization Tips
+
+### For Speed
+
+1. Use smaller models (tiny/base)
+2. Increase parallel chunks
+3. Disable diarization
+4. Skip post-processing
+5. Use GPU acceleration
+
+### For Accuracy
+
+1. Use larger models (medium/large)
+2. Enable all pre-processing
+3. Reduce chunk size
+4. Enable silence detection
+5. Multiple pass processing
+
+### For Cost
+
+1. Use Modal spot instances
+2. Batch multiple files
+3. Cache common phrases
+4. Optimize chunk size
+5. Selective post-processing
+
+## Monitoring
+
+### Metrics to Track
+
+```python
+metrics = {
+    "processing_time": histogram,
+    "chunk_success_rate": gauge,
+    "model_accuracy": histogram,
+    "queue_depth": gauge,
+    "gpu_utilization": gauge,
+    "cost_per_hour": counter
+}
+```
+
+### Quality Metrics
+
+- Word Error Rate (WER)
+- Diarization Error Rate (DER)
+- Confidence scores
+- Processing speed
+- User feedback
+
+### Alerts
+
+- Processing time > 30 minutes
+- Error rate > 5%
+- Queue depth > 100
+- GPU memory > 90%
+- Cost spike detected

+# Transcript Formats
+
+The Reflector API provides multiple output formats for transcript data through the `transcript_format` query parameter on the GET `/v1/transcripts/{id}` endpoint.
+
+## Overview
+
+When retrieving a transcript, you can specify the desired format using the `transcript_format` query parameter. The API supports four formats optimized for different use cases:
+
+- **text** - Plain text with speaker names (default)
+- **text-timestamped** - Timestamped text with speaker names
+- **webvtt-named** - WebVTT subtitle format with participant names
+- **json** - Structured JSON segments with full metadata
+
+All formats include participant information when available, resolving speaker IDs to actual names.
+
+## Query Parameter Usage
+
+```
+GET /v1/transcripts/{id}?transcript_format={format}
+```
+
+### Parameters
+
+- `transcript_format` (optional): The desired output format
+  - Type: `"text" | "text-timestamped" | "webvtt-named" | "json"`
+  - Default: `"text"`
+
+## Format Descriptions
+
+### Text Format (`text`)
+
+**Use case:** Simple, human-readable transcript for display or export.
+
+**Format:** Speaker names followed by their dialogue, one line per segment.
+
+**Example:**
+```
+John Smith: Hello everyone
+Jane Doe: Hi there
+John Smith: How are you today?
+```
+
+**Request:**
+```bash
+GET /v1/transcripts/{id}?transcript_format=text
+```
+
+**Response:**
+```json
+{
+  "id": "transcript_123",
+  "name": "Meeting Recording",
+  "transcript_format": "text",
+  "transcript": "John Smith: Hello everyone\nJane Doe: Hi there\nJohn Smith: How are you today?",
+  "participants": [
+    {"id": "p1", "speaker": 0, "name": "John Smith"},
+    {"id": "p2", "speaker": 1, "name": "Jane Doe"}
+  ],
+  ...
+}
+```
+
+### Text Timestamped Format (`text-timestamped`)
+
+**Use case:** Transcript with timing information for navigation or reference.
+
+**Format:** `[MM:SS]` timestamp prefix before each speaker and dialogue.
+
+**Example:**
+```
+[00:00] John Smith: Hello everyone
+[00:05] Jane Doe: Hi there
+[00:12] John Smith: How are you today?
+```
+
+**Request:**
+```bash
+GET /v1/transcripts/{id}?transcript_format=text-timestamped
+```
+
+**Response:**
+```json
+{
+  "id": "transcript_123",
+  "name": "Meeting Recording",
+  "transcript_format": "text-timestamped",
+  "transcript": "[00:00] John Smith: Hello everyone\n[00:05] Jane Doe: Hi there\n[00:12] John Smith: How are you today?",
+  "participants": [
+    {"id": "p1", "speaker": 0, "name": "John Smith"},
+    {"id": "p2", "speaker": 1, "name": "Jane Doe"}
+  ],
+  ...
+}
+```
+
+### WebVTT Named Format (`webvtt-named`)
+
+**Use case:** Subtitle files for video players, accessibility tools, or video editing.
+
+**Format:** Standard WebVTT subtitle format with voice tags using participant names.
+
+**Example:**
+```
+WEBVTT
+
+00:00:00.000 --> 00:00:05.000
+<v John Smith>Hello everyone
+
+00:00:05.000 --> 00:00:12.000
+<v Jane Doe>Hi there
+
+00:00:12.000 --> 00:00:18.000
+<v John Smith>How are you today?
+```
+
+**Request:**
+```bash
+GET /v1/transcripts/{id}?transcript_format=webvtt-named
+```
+
+**Response:**
+```json
+{
+  "id": "transcript_123",
+  "name": "Meeting Recording",
+  "transcript_format": "webvtt-named",
+  "transcript": "WEBVTT\n\n00:00:00.000 --> 00:00:05.000\n<v John Smith>Hello everyone\n\n...",
+  "participants": [
+    {"id": "p1", "speaker": 0, "name": "John Smith"},
+    {"id": "p2", "speaker": 1, "name": "Jane Doe"}
+  ],
+  ...
+}
+```
+
+### JSON Format (`json`)
+
+**Use case:** Programmatic access with full timing and speaker metadata.
+
+**Format:** Array of segment objects with speaker information, text content, and precise timing.
+
+**Example:**
+```json
+[
+  {
+    "speaker": 0,
+    "speaker_name": "John Smith",
+    "text": "Hello everyone",
+    "start": 0.0,

+
+## Response Structure
+
+All formats return the same base transcript metadata with an additional `transcript_format` field and format-specific `transcript` field:
+
+### Common Fields
+
+- `id`: Transcript identifier
+- `user_id`: Owner user ID (if authenticated)
+- `name`: Transcript name
+- `status`: Processing status
+- `locked`: Whether transcript is locked for editing
+- `duration`: Total duration in seconds
+- `title`: Auto-generated or custom title
+- `short_summary`: Brief summary
+- `long_summary`: Detailed summary
+- `created_at`: Creation timestamp
+- `share_mode`: Access control setting
+- `source_language`: Original audio language
+- `target_language`: Translation target language
+- `reviewed`: Whether transcript has been reviewed
+- `meeting_id`: Associated meeting ID (if applicable)
+- `source_kind`: Source type (live, file, room)
+- `room_id`: Associated room ID (if applicable)
+- `audio_deleted`: Whether audio has been deleted
+- `participants`: Array of participant objects with speaker mappings
+
+### Format-Specific Fields
+
+- `transcript_format`: The format identifier (discriminator field)
+- `transcript`: The formatted transcript content (string for text/webvtt formats, array for json format)
+
+## Speaker Name Resolution
+
+All formats resolve speaker IDs to participant names when available:
+
+- If a participant exists for the speaker ID, their name is used
+- If no participant exists, a default name like "Speaker 0" is generated
+- Speaker IDs are integers (0, 1, 2, etc.) assigned during diarization

+# Reflector GPU implementation - Transcription and LLM
+
+This repository hold an API for the GPU implementation of the Reflector API service,
+and use [Modal.com](https://modal.com)
+
+- `reflector_diarizer.py` - Diarization API
+- `reflector_transcriber.py` - Transcription API (Whisper)
+- `reflector_transcriber_parakeet.py` - Transcription API (NVIDIA Parakeet)
+- `reflector_translator.py` - Translation API
+
+## Modal.com deployment
+
+Create a modal secret, and name it `reflector-gpu`.
+It should contain an `REFLECTOR_APIKEY` environment variable with a value.
+
+The deployment is done using [Modal.com](https://modal.com) service.
+
+```
+$ modal deploy reflector_transcriber.py
+...
+└── 🔨 Created web => https://xxxx--reflector-transcriber-web.modal.run
+
+$ modal deploy reflector_transcriber_parakeet.py
+...
+└── 🔨 Created web => https://xxxx--reflector-transcriber-parakeet-web.modal.run
+
+$ modal deploy reflector_llm.py
+...
+└── 🔨 Created web => https://xxxx--reflector-llm-web.modal.run
+```
+
+Then in your reflector api configuration `.env`, you can set these keys:
+
+```
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=https://xxxx--reflector-transcriber-web.modal.run
+TRANSCRIPT_MODAL_API_KEY=REFLECTOR_APIKEY
+
+DIARIZATION_BACKEND=modal
+DIARIZATION_URL=https://xxxx--reflector-diarizer-web.modal.run
+DIARIZATION_MODAL_API_KEY=REFLECTOR_APIKEY
+
+TRANSLATION_BACKEND=modal
+TRANSLATION_URL=https://xxxx--reflector-translator-web.modal.run
+TRANSLATION_MODAL_API_KEY=REFLECTOR_APIKEY
+```
+
+## API
+
+Authentication must be passed with the `Authorization` header, using the `bearer` scheme.
+
+```
+Authorization: bearer <REFLECTOR_APIKEY>
+```
+
+### LLM
+
+`POST /llm`
+
+**request**
+```
+{
+    "prompt": "xxx"

+### Transcription
+
+#### Parakeet Transcriber (`reflector_transcriber_parakeet.py`)
+
+NVIDIA Parakeet is a state-of-the-art ASR model optimized for real-time transcription with superior word-level timestamps.
+
+**GPU Configuration:**
+- **A10G GPU** - Used for `/v1/audio/transcriptions` endpoint (small files, live transcription)
+  - Higher concurrency (max_inputs=10)
+  - Optimized for multiple small audio files
+  - Supports batch processing for efficiency
+
+- **L40S GPU** - Used for `/v1/audio/transcriptions-from-url` endpoint (large files)
+  - Lower concurrency but more powerful processing
+  - Optimized for single large audio files
+  - VAD-based chunking for long-form audio
+
+##### `/v1/audio/transcriptions` - Small file transcription
+
+**request** (multipart/form-data)
+- `file` or `files[]` - audio file(s) to transcribe
+- `model` - model name (default: `nvidia/parakeet-tdt-0.6b-v2`)
+- `language` - language code (default: `en`)
+- `batch` - whether to use batch processing for multiple files (default: `true`)
+
+**response**
+```json
+{
+    "text": "transcribed text",
+    "words": [
+        {"word": "hello", "start": 0.0, "end": 0.5},
+        {"word": "world", "start": 0.5, "end": 1.0}
+    ],
+    "filename": "audio.mp3"
+}
+```
+
+For multiple files with batch=true:
+```json
+{
+    "results": [
+        {
+            "filename": "audio1.mp3",
+            "text": "transcribed text",
+            "words": [...]
+        },
+        {
+            "filename": "audio2.mp3",
+            "text": "transcribed text",
+            "words": [...]
+        }
+    ]
+}
+```
+
+##### `/v1/audio/transcriptions-from-url` - Large file transcription
+
+**request** (application/json)
+```json
+{
+    "audio_file_url": "https://example.com/audio.mp3",
+    "model": "nvidia/parakeet-tdt-0.6b-v2",
+    "language": "en",
+    "timestamp_offset": 0.0

+
+**response**
+```json
+{
+    "text": "transcribed text from large file",
+    "words": [
+        {"word": "hello", "start": 0.0, "end": 0.5},
+        {"word": "world", "start": 0.5, "end": 1.0}
+    ]
+}
+```
+
+**Supported file types:** mp3, mp4, mpeg, mpga, m4a, wav, webm
+
+#### Whisper Transcriber (`reflector_transcriber.py`)
+
+`POST /transcribe`
+
+**request** (multipart/form-data)
+
+- `file` - audio file
+- `language` - language code (e.g. `en`)
+
+**response**
+```
+{
+    "text": "xxx",
+    "words": [
+        {"text": "xxx", "start": 0.0, "end": 1.0}

+# Local Development GPU Setup
+
+Run transcription and diarization locally for development/testing.
+
+> **For production deployment**, see the [Self-Hosted GPU Setup Guide](../../docs/docs/installation/self-hosted-gpu-setup.md).
+
+## Prerequisites
+
+1. **Python 3.12+** and **uv** package manager
+2. **FFmpeg** installed and on PATH
+3. **HuggingFace account** with access to pyannote models
+
+### Accept Pyannote Licenses (Required)
+
+Before first run, accept licenses for these gated models (logged into HuggingFace):
+- https://hf.co/pyannote/speaker-diarization-3.1
+- https://hf.co/pyannote/segmentation-3.0
+
+## Quick Start
+
+### 1. Install dependencies
+
+```bash
+cd gpu/self_hosted
+uv sync
+```
+
+### 2. Start the GPU service
+
+```bash
+cd gpu/self_hosted
+HF_TOKEN=<your-huggingface-token> \
+REFLECTOR_GPU_APIKEY=dev-key-12345 \
+.venv/bin/uvicorn main:app --host 0.0.0.0 --port 8000
+```
+
+Note: The `.env` file is NOT auto-loaded. Pass env vars explicitly or use:
+```bash
+export HF_TOKEN=<your-token>
+export REFLECTOR_GPU_APIKEY=dev-key-12345
+.venv/bin/uvicorn main:app --host 0.0.0.0 --port 8000
+```
+
+### 3. Configure Reflector to use local GPU
+
+Edit `server/.env`:
+
+```bash
+# Transcription - local GPU service
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=http://host.docker.internal:8000
+TRANSCRIPT_MODAL_API_KEY=dev-key-12345
+
+# Diarization - local GPU service
+DIARIZATION_BACKEND=modal
+DIARIZATION_URL=http://host.docker.internal:8000
+DIARIZATION_MODAL_API_KEY=dev-key-12345
+```
+
+Note: Use `host.docker.internal` because Reflector server runs in Docker.
+
+### 4. Restart Reflector server
+
+```bash
+cd server
+docker compose restart server worker
+```
+
+## Testing
+
+### Test transcription

+
+## Platform Notes
+
+### macOS (ARM)
+
+Docker build fails - CUDA packages are x86_64 only. Use local Python instead:
+```bash
+uv sync
+HF_TOKEN=xxx REFLECTOR_GPU_APIKEY=xxx .venv/bin/uvicorn main:app --host 0.0.0.0 --port 8000
+```
+
+### Linux with NVIDIA GPU
+
+Docker works with CUDA acceleration:
+```bash
+docker compose up -d
+```
+
+### CPU-only
+
+Works on any platform, just slower. PyTorch auto-detects and falls back to CPU.
+
+## Switching Back to Modal.com
+
+Edit `server/.env`:
+
+```bash
+TRANSCRIPT_BACKEND=modal
+TRANSCRIPT_URL=https://monadical-sas--reflector-transcriber-parakeet-web.modal.run
+TRANSCRIPT_MODAL_API_KEY=<modal-api-key>
+
+DIARIZATION_BACKEND=modal
+DIARIZATION_URL=https://monadical-sas--reflector-diarizer-web.modal.run
+DIARIZATION_MODAL_API_KEY=<modal-api-key>
+```
+
+## Troubleshooting
+
+### "Could not download pyannote pipeline"
+- Accept model licenses at HuggingFace (see Prerequisites)
+- Verify HF_TOKEN is set and valid
+
+### Service won't start
+- Check port 8000 is free: `lsof -i :8000`
+- Kill orphan processes if needed
+
+### Transcription returns empty text
+- Ensure audio contains speech (not just tones/silence)
+- Check audio format is supported (wav, mp3, etc.)
+
+### Deprecation warnings from torchaudio/pyannote
+- Safe to ignore - doesn't affect functionality
