**Remaining**: 9 models (waiting for documentation)

---

### **2. Backend APIs** ✅ **COMPLETE**

#### **2.1 Get Available Models** ✅
**Endpoint**: `GET /api/image-studio/edit/models`

**Query Parameters**:
- `operation` (optional): Filter by operation type
- `tier` (optional): Filter by tier (budget, mid, premium)

**Response**:
```json
{
  "models": [
    {
      "id": "qwen-edit-plus",
      "name": "Qwen Image Edit Plus",
      "description": "...",
      "cost": 0.02,
      "tier": "budget",
      "max_resolution": [1536, 1536],
      "capabilities": ["general_edit", "multi_image"],
      "use_cases": ["Quick edits", "Batch editing"],
      "features": ["ControlNet support", "Bilingual (CN/EN)"],
      "supports_multi_image": true,
      "supports_controlnet": true,
      "languages": ["en", "zh"]
    }
  ],
  "total": 5
}
```

#### **2.2 Get Model Recommendations** ✅
**Endpoint**: `POST /api/image-studio/edit/recommend`

**Request Body**:
```json
{
  "operation": "general_edit",
  "image_resolution": { "width": 1024, "height": 1024 },
  "user_tier": "free",
  "preferences": {
    "prioritize_cost": true,
    "prioritize_quality": false
  }
}
```

**Response**:
```json
{
  "recommended_model": "qwen-edit",
  "reason": "Lowest cost option, Supports 1024×1024 resolution, Budget-friendly for free tier",
  "alternatives": [
    {
      "model_id": "qwen-edit-plus",
      "name": "Qwen Image Edit Plus",
      "cost": 0.02,
      "reason": "Alternative: Budget tier, higher quality"
    }
  ]
}
```

### **3. Auto-Detection & Routing** ✅ **COMPLETE**

**Implementation**: `EditStudioService._handle_general_edit()`

**Logic**:
1. **If model specified**: Use that model (WaveSpeed or HuggingFace)
2. **If no model specified** (general_edit operation):
   - Auto-detect image resolution
   - Call recommendation logic
   - Auto-select recommended WaveSpeed model
   - Fall back to HuggingFace if no WaveSpeed model matches

**Features**:
- ✅ Automatic model selection based on image resolution
- ✅ Cost-optimized by default (prioritize_cost: true)
- ✅ Logs auto-selection reason for transparency
- ✅ Graceful fallback to HuggingFace if needed

---

### **4. Recommendation Algorithm** ✅ **COMPLETE**

**Scoring Factors**:
1. **Cost** (weighted by `prioritize_cost` preference)
2. **Quality** (max resolution, weighted by `prioritize_quality`)
3. **User Tier** (free users → budget models, pro → premium)
4. **Image Resolution** (filters models that don't support input size)

**Scoring Formula**:
```python
score = (
    (1.0 / cost) * cost_weight +           # Lower cost = higher score
    max_resolution / resolution_weight +    # Higher res = higher score
    tier_bonus                             # Based on user tier
)
```

**Result**: Returns best matching model with explanation and alternatives

---

### **5. Service Layer Methods** ✅ **COMPLETE**

**Added to `EditStudioService`**:
- ✅ `get_available_models()` - List models with metadata
- ✅ `recommend_model()` - Smart recommendation algorithm
- ✅ `_get_use_cases_for_model()` - Generate use cases from capabilities
- ✅ `_get_features_for_model()` - Generate feature list

**Added to `ImageStudioManager`**:
- ✅ `get_edit_models()` - Expose model listing
- ✅ `recommend_edit_model()` - Expose recommendations

---

## 📋 Frontend Integration (Pending)

### **Required Components**

1. **ModelSelector Component**
   - Dropdown/select with search
   - Group by tier
   - Show cost and features
   - Display recommendations

2. **ModelInfoCard Component**
   - Model details
   - Use cases
   - Features
   - Cost information

3. **ModelComparisonDialog Component**
   - Side-by-side comparison
   - Filterable table
   - Quick select

4. **ModelRecommendationBadge Component**
   - Show recommendation reason
   - Dismissible

### **Integration Points**

1. **EditStudio.tsx**
   - Add model selector to UI
   - Call `/api/image-studio/edit/models` on load
   - Call `/api/image-studio/edit/recommend` for auto-selection
   - Display model info and cost
   - Pass selected model to request

2. **useImageStudio Hook**
   - Add `loadEditModels()` function
   - Add `getModelRecommendation()` function
   - Add model selection state

2. Create `ModelInfoCard` component
3. Create `ModelComparisonDialog` component
4. Integrate into `EditStudio.tsx`
5. Add API calls to `useImageStudio` hook

### **Future (More Models)**
1. Add remaining 9 editing models (once docs provided)
2. Enhance recommendation algorithm with usage history
3. Add model performance metrics
4. Add user feedback/rating system
