|
|
|
|

|
**Status**: ✅ Complete and tested
|
|
|

|
|
|
|
### **Step 2: WaveSpeedEditProvider Structure** ✅
|
|
|
|
**File**: `backend/services/llm_providers/image_generation/wavespeed_edit_provider.py`
|
|
|
|
**Created**:
|
|
- ✅ Provider class structure following `WaveSpeedImageProvider` pattern
|
|
- ✅ `SUPPORTED_MODELS` dict (empty, ready for 14 models)
|
|
- ✅ Validation methods (`_validate_options()`)
|
|
- ✅ Helper methods (`get_available_models()`, `get_models_by_tier()`, `get_models_by_operation()`)
|
|
- ✅ Placeholder for API call method (`_call_wavespeed_edit_api()`)
|
|
|
|
**Status**: ✅ Structure complete, API implemented
|
|
- ✅ `SUPPORTED_MODELS` dict structure ready
|
|
- ✅ API call method (`_call_wavespeed_edit_api()`) implemented
|
|
- ✅ Helper methods (`_extract_image_url()`, `_download_image()`) added
|
|
- ✅ 5 models added: `qwen-edit`, `qwen-edit-plus`, `nano-banana-pro-edit-ultra`, `seedream-v4.5-edit`, `flux-kontext-pro` (waiting for remaining 9 model docs)
|
|
- ✅ Model-specific parameter handling: Supports different API formats (size vs aspect_ratio/resolution, image vs images)
|
|
- ✅ Verified against official WaveSpeed API documentation
|
|
- ✅ Qwen Image Edit: Verified against https://wavespeed.ai/docs/docs-api/wavespeed-ai/qwen-image-edit
|

## 📋 Ready for Model Integration
|
|
|
|
### **What I Need from You**
|
|
|
|
1. **Model Documentation** for each of the 14 editing models:
|
|
- Model ID (e.g., "qwen-edit")
|
|
- Model path/endpoint (e.g., "wavespeed-ai/qwen-image/edit")
|
|
- Display name
|
|
- Cost per edit
|
|
- Max resolution
|
|
- Supported operations/capabilities
|
|
- Any model-specific parameters
|
|
|
|
2. **WaveSpeed API Documentation** for editing:
|
|
- API endpoint structure
|
|
- Request format
|
|
- Response format
|
|
- Authentication method
|
|
- Any special requirements
|
|
|
|
### **Model Structure Example**
|
|
|
|
**Qwen Image Edit Plus** (✅ Added):
|
|
```python
|
|
"qwen-edit-plus": {
|
|
"model_path": "wavespeed-ai/qwen-image/edit-plus",
|
|
"name": "Qwen Image Edit Plus",
|
|
"description": "20B MMDiT image editor with multi-image editing...",
|
|
"cost": 0.02,
|
|
"max_resolution": (1536, 1536),
|
|
"capabilities": ["general_edit", "style_transfer", "text_edit", "multi_image"],
|
|
"tier": "budget",
|
|
"supports_multi_image": True, # Up to 3 reference images
|
|
"supports_controlnet": True,
|
|
"languages": ["en", "zh"],
|
|
}
|
|
```
|
|
|
|
**Template for Remaining Models**:
|
|
```python
|
|
"model-id": {
|
|
"model_path": "wavespeed-ai/model-path",
|
|
"name": "Model Display Name",
|
|
"description": "Model description",
|
|
"cost": 0.02, # Cost per edit
|
|
"max_resolution": (2048, 2048),
|
|
"capabilities": ["general_edit", "inpaint", "outpaint"],
|
|
"tier": "budget", # "budget", "mid", "premium"
|
|
# Model-specific parameters
|
|
}
|
|
```
|
|

## 🔄 Next Steps (After Model Docs)
|
|
|
|
### **Step 3: Add Models** (In Progress - 2/14 Complete)
|
|
- ✅ **Qwen Image Edit Plus** added (from provided docs)
|
|
- ✅ **Google Nano Banana Pro Edit Ultra** added (from provided docs)
|
|
- ⏳ **12 models remaining** - waiting for model documentation
|
|
- Model-specific parameter handling: Supports both `size` (Qwen) and `aspect_ratio`/`resolution` (Nano Banana) formats
|
|
|
|
### **Step 4: Implement API Call** ✅ **COMPLETE**
|
|
- ✅ `_call_wavespeed_edit_api()` method implemented
|
|
- ✅ Follows same pattern as `ImageGenerator.generate_image()`
|
|
- ✅ Handles sync/async modes
|
|
- ✅ Polling support via `WaveSpeedClient.poll_until_complete()`
|
|
- ✅ Helper methods: `_extract_image_url()`, `_download_image()`
|
|
- ✅ Tested with Qwen Image Edit Plus API structure
|
|
|
|
### **Step 5: Unified Entry Point** ✅ **COMPLETE**
|
|
- ✅ `generate_image_edit()` added to `main_image_generation.py`
|
|
- ✅ Reuses Phase 1 helpers (`_validate_image_operation()`, `_track_image_operation_usage()`)
|
|
- ✅ Provider selection helper (`_get_edit_provider()`) added
|
|
- ✅ Follows same pattern as `generate_image()`
|
|
- ✅ Error handling and logging consistent
|
|
|
|
### **Step 6: Service Integration** ✅ **COMPLETE**
|
|
- ✅ Refactored `_handle_general_edit()` to use unified entry point for WaveSpeed models
|
|
- ✅ Added model detection logic (WaveSpeed vs HuggingFace)
|
|
- ✅ Maintained backward compatibility with Stability AI and HuggingFace
|
|
- ✅ API endpoint already supports `model` parameter (no changes needed)
|
|
|
|
### **Step 7: Backend APIs** ✅ **COMPLETE**
|
|
- ✅ `GET /api/image-studio/edit/models` - List available models with metadata
|
|
- ✅ `POST /api/image-studio/edit/recommend` - Get smart recommendations
|
|
- ✅ Auto-detection logic implemented in `_handle_general_edit()`
|
|
- ✅ Recommendation algorithm with scoring (cost, quality, user tier, resolution)
|
|
- ✅ Model metadata methods (`get_available_models()`, `recommend_model()`)
|
|
|
|
### **Step 8: Frontend Integration** ⏸️ **PENDING**
|
|
- ⏸️ Create `ModelSelector` component
|
|
- ⏸️ Create `ModelInfoCard` component
|
|
- ⏸️ Create `ModelComparisonDialog` component
|
|
- ⏸️ Integrate into `EditStudio.tsx`
|
|
- ⏸️ Add API calls to `useImageStudio` hook
|
|
- ⏸️ Display cost estimates and model information
|
|

## 📝 Notes
|
|
|
|
1. **Reusability**: All code follows established patterns from Phase 1
|
|
2. **Placeholder API Call**: `_call_wavespeed_edit_api()` is a placeholder - will be implemented once we have API docs
|
|
3. **Model Registry**: Structure ready, just needs model data
|
|
4. **Backward Compatibility**: Will be maintained when integrating with `EditStudioService`
|
