# Text-to-Video Phase 1 - Implementation Status

## ✅ Base Structure Created

### Directory Structure
```
backend/services/llm_providers/video_generation/
├── __init__.py                    # Module exports
├── base.py                        # Base classes and interfaces
└── wavespeed_provider.py          # WaveSpeed text-to-video services
```

### Files Created

1. **`base.py`** - Base classes:
   - `VideoGenerationOptions` - Options dataclass
   - `VideoGenerationResult` - Result dataclass
   - `VideoGenerationProvider` - Protocol interface

2. **`wavespeed_provider.py`** - WaveSpeed services:
   - `BaseWaveSpeedTextToVideoService` - Base class with common logic
   - `HunyuanVideoService` - Placeholder for HunyuanVideo-1.5
   - `get_wavespeed_text_to_video_service()` - Factory function

### Architecture

**Separation of Concerns:**
- Each model has its own service class
- Base class handles common validation and structure
- Factory function routes to appropriate service
- Follows same pattern as `image_generation/` module

**Current Status:**
- ✅ Base structure created
- ✅ HunyuanVideoService placeholder created
- ⏳ Waiting for model documentation to implement

## Next Steps

### 1. Provide Model Documentation
Please provide documentation for **HunyuanVideo-1.5** including:
- API endpoint path
- Request payload structure
- Required parameters
- Optional parameters
- Response format
- Pricing/cost calculation
- Any special features or limitations

### 2. Implement HunyuanVideoService
Once documentation is provided, I will:
- Implement `generate_video()` method
- Add proper validation
- Integrate with WaveSpeedClient
- Add progress callback support
- Return proper metadata dict

### 3. Integrate into Unified Entry Point
- Add `_generate_text_to_video_wavespeed()` to `main_video_generation.py`
- Route to appropriate service based on model
- Handle async/sync properly

### 4. Test and Validate
- Test with real API calls
- Verify all features work
- Ensure backward compatibility

### 5. Add Remaining Models
- Follow same pattern for LTX-2 Pro, Fast, Retake
- Reuse common logic
- Model-specific differences only

## Model Selection

**Starting Model:** **HunyuanVideo-1.5**
- Most commonly used
- Good documentation availability
- Standard parameters

**Alternative:** Any model you prefer - we'll follow the same pattern.

## Ready for Documentation

The structure is ready. Please provide:
1. **HunyuanVideo-1.5 API documentation**
2. **Any specific requirements or features**
3. **Pricing information** (if available)

Once provided, I'll implement the service following the established pattern.
