### **3. API Implementation** ✅
- ✅ `_call_wavespeed_edit_api()` method implemented
- ✅ Follows same pattern as `ImageGenerator.generate_image()`

## 📋 Current Implementation

### **Usage Example**

```python
from services.llm_providers.main_image_generation import generate_image_edit

# Edit image using unified entry point
result = generate_image_edit(
    image_base64=image_base64_string,
    prompt="Change the background to a beach scene",
    operation="general_edit",
    model="qwen-edit-plus",  # Optional - defaults to first available
    options={
        "width": 1024,
        "height": 1024,
        "seed": 42,
    },
    user_id=user_id
)

# Result contains edited image
edited_image_bytes = result.image_bytes
```

## ⏳ Waiting For

### **Remaining 9 Models** (Need Documentation)

1. Step1X Edit
2. HiDream E1 Full
4. SeedEdit V3
5. Alibaba WAN 2.5 Image Edit
6. FLUX Kontext Pro
7. FLUX Kontext Pro Multi
8. FLUX Kontext Max
9. Ideogram Character
10. OpenAI GPT Image 1
11. Z-Image Turbo Inpaint
12. Image Zoom-Out

**For each model, I need**:
- Model path/endpoint
- Cost per edit
- Max resolution
- Supported operations
- Any model-specific parameters

---

## 🎯 Next Steps

1. **Add Remaining Models** (Once docs provided)
   - See `IMAGE_STUDIO_EDITING_RECOMMENDED_MODELS.md` for prioritized list
   - Recommended next: Qwen Image Edit (basic), WAN 2.5 Edit, Step1X Edit
   - Populate `SUPPORTED_MODELS` with remaining models

2. **Service Integration** ✅ **COMPLETE** (Step 6)
   - ✅ Refactored `EditStudioService` to use `generate_image_edit()`
   - ✅ Maintained backward compatibility with Stability AI and HuggingFace
   - ✅ Automatic routing based on model/provider

3. **API Endpoint** ✅ **COMPLETE** (Step 7)
   - ✅ `/api/image-studio/edit/process` already supports `model` parameter
   - ✅ No changes needed

4. **Frontend** (Step 8) - ⏸️ **PENDING**
   - Add model selector to `EditStudio.tsx`
   - Show cost/quality comparison
   - Display available models by tier
