+# Image Studio Editing - Service Integration Summary
+
+**Date**: Current Session  
+**Status**: ✅ **COMPLETE** - Service Integration with 3 WaveSpeed Models
+
+---
+
+## ✅ Completed Integration
+
+### **Service Layer Refactoring**
+
+**File**: `backend/services/image_studio/edit_service.py`
+
+**Changes**:
+1. ✅ Added import for `generate_image_edit` from unified entry point
+2. ✅ Refactored `_handle_general_edit()` method to:
+   - Detect WaveSpeed models (`qwen-edit-plus`, `nano-banana-pro-edit-ultra`, `seedream-v4.5-edit`)
+   - Route to unified entry point for WaveSpeed models
+   - Fall back to HuggingFace for backward compatibility
+3. ✅ Maintained all existing functionality:
+   - Stability AI operations (remove_background, inpaint, outpaint, etc.) - unchanged
+   - HuggingFace general_edit - still works as before
+   - Pre-flight validation - unchanged
+   - Response format - unchanged
+
+### **Routing Logic**
+
+```python
+# Detection logic:
+wavespeed_models = {
+    "qwen-edit-plus",
+    "nano-banana-pro-edit-ultra", 
+    "seedream-v4.5-edit",
+}
+
+is_wavespeed = (
+    request.provider == "wavespeed" or
+    (request.model and request.model in wavespeed_models)
+)
+```
+
+**If WaveSpeed**:
+- Uses `generate_image_edit()` unified entry point
+- Gets validation, tracking, and error handling automatically
+- Supports all 3 integrated models
+
+**If Not WaveSpeed**:
+- Falls back to HuggingFace (legacy behavior)
+- Maintains backward compatibility
+
+---
+
+## 🔄 API Endpoint
+
+**File**: `backend/routers/image_studio.py`
+
+**Status**: ✅ No changes needed
+- `EditImageRequest` already includes `model` parameter (line 88)
+- Endpoint `/api/image-studio/edit/process` already accepts `model`
+- Service layer handles routing automatically
+
+**Usage Example**:
+```json
+{
+  "image_base64": "...",
+  "operation": "general_edit",
+  "prompt": "Change the background to a beach scene",
+  "model": "qwen-edit-plus",  // WaveSpeed model
+  "provider": "wavespeed"     // Optional, auto-detected from model
+}
+```
+
+---
+
+## ✅ Backward Compatibility
+
+### **Stability AI Operations** (Unchanged)
+- `remove_background` → Still uses Stability AI
+- `inpaint` → Still uses Stability AI
+- `outpaint` → Still uses Stability AI
+- `search_replace` → Still uses Stability AI
+- `search_recolor` → Still uses Stability AI
+- `relight` → Still uses Stability AI
+
+### **HuggingFace General Edit** (Fallback)
+- If `model` is not a WaveSpeed model → Uses HuggingFace
+- If `provider` is not "wavespeed" → Uses HuggingFace
+- All existing HuggingFace functionality preserved
+
+### **WaveSpeed Models** (New)
+- If `model` is one of: `qwen-edit-plus`, `nano-banana-pro-edit-ultra`, `seedream-v4.5-edit`
+- Or if `provider` is "wavespeed"
+- → Routes to unified entry point

+## 🎯 Testing Checklist
+
+- [ ] Test WaveSpeed model selection (`qwen-edit-plus`)
+- [ ] Test WaveSpeed model selection (`nano-banana-pro-edit-ultra`)
+- [ ] Test WaveSpeed model selection (`seedream-v4.5-edit`)
+- [ ] Test HuggingFace fallback (no model or non-WaveSpeed model)
+- [ ] Test Stability AI operations (unchanged)
+- [ ] Test pre-flight validation (unchanged)
+- [ ] Test error handling
+- [ ] Test backward compatibility with existing clients

+
+## 📝 Notes
+
+1. **No Breaking Changes**: All existing API calls continue to work
+2. **Opt-in Enhancement**: WaveSpeed models are opt-in via `model` parameter
+3. **Automatic Routing**: Service automatically detects and routes to appropriate provider
+4. **Unified Benefits**: WaveSpeed models get validation, tracking, and error handling from unified entry point
