# Image Studio: Unified Architecture & Integration Patterns
**Purpose**: Define **reusable** code patterns and architecture for integrating 40+ WaveSpeed AI models into Image Studio
**Status**: Architecture Proposal - Pre-Implementation Review
**Based On**: Existing `main_image_generation.py` + Video Studio patterns
**Key Principle**: **REUSABILITY** - Extend existing code, don't duplicate
---
## 📊 Executive Summary
This document proposes a **reusable architecture** for Image Studio that:
1. **✅ Extends Existing Code**: Builds on `main_image_generation.py` (already exists)
2. **✅ Extracts Reusable Helpers**: Validation and tracking from existing functions
3. **✅ Reuses Provider Pattern**: Extends `ImageGenerationProvider` protocol
4. **✅ Reuses Infrastructure**: WaveSpeedClient, validation, tracking logic
5. **✅ Scales to 40+ Models**: Easy addition by following existing patterns
---
## 🔍 Current State Analysis
### **Video Studio Pattern** (`main_video_generation.py`) - Reference
#### **Architecture**
```
┌─────────────────────────────────────────┐
│ ai_video_generate() │ ← Unified Entry Point
│ - Pre-flight validation │
│ - Provider routing │
│ - Usage tracking │
│ - Progress callbacks │
└──────────────┬──────────────────────────┘
│
┌───────┴────────┐
│ │
┌──────▼──────┐ ┌─────▼──────────┐
│ HuggingFace │ │ WaveSpeed │
│ Provider │ │ Provider │
└─────────────┘ └────────────────┘
```
#### **Key Patterns**
1. **Unified Entry Point**: `ai_video_generate()` handles all video operations
2. **Pre-flight Validation**: Subscription checks BEFORE API calls
3. **Provider Abstraction**: Routes to provider-specific handlers
4. **Standardized Returns**: Always returns `Dict[str, Any]` with consistent keys
5. **Usage Tracking**: Centralized `track_video_usage()` function
6. **Progress Callbacks**: Optional progress updates for async operations
7. **Error Handling**: Consistent HTTPException patterns
---
### **Image Studio Current Pattern** ✅ **ALREADY EXISTS**
#### **Architecture**
```
┌─────────────────────────────────────────┐
│ main_image_generation.py │ ← Unified Entry Point (EXISTS)
│ - generate_image() │
│ - generate_character_image() │
│ - Pre-flight validation │
│ - Usage tracking │
└──────────────┬──────────────────────────┘
│
┌──────────┼──────────┐
│ │ │
┌───▼───┐ ┌───▼───┐ ┌───▼───┐
│Create │ │ Edit │ │Upscale│
│Service│ │Service│ │Service│
└───┬───┘ └───┬───┘ └───┬───┘
│ │ │
┌───▼──────────▼──────────▼───┐
│ image_generation/ │
│ - ImageGenerationProvider │ ← Protocol (EXISTS)
│ - WaveSpeedImageProvider │
│ - StabilityImageProvider │
│ - HuggingFaceImageProvider │
│ - GeminiImageProvider │
└──────────────────────────────┘
```
#### **Current Implementation** ✅
1. **✅ Unified Entry Point EXISTS**: `main_image_generation.py` with `generate_image()`
2. **✅ Pre-flight Validation**: Implemented in `generate_image()`
3. **✅ Provider Abstraction**: `ImageGenerationProvider` protocol with implementations
4. **✅ Usage Tracking**: Implemented in `generate_image()`
5. **✅ Standardized Returns**: `ImageGenerationResult` dataclass
#### **Current Usage**
- ✅ **Used by**: YouTube, Podcast, Story Writer, Facebook Writer, LinkedIn
- ⚠️ **NOT used by**: `CreateStudioService` (uses providers directly)
- ⚠️ **Missing**: Editing, Upscaling, 3D operations don't use unified entry
#### **Reusability Opportunities**
1. **Extend `main_image_generation.py`** for editing operations
2. **Reuse provider pattern** for new WaveSpeed models
3. **Standardize all services** to use unified entry point
4. **Extract common validation/tracking** into reusable functions
---
## 🎯 Proposed Architecture Enhancement
### **Core Principle: Extend Existing Pattern for Maximum Reusability**
**Build on existing `main_image_generation.py`** instead of creating new modules. Extend it to support all image operations while maintaining the proven pattern.
### **Enhanced Architecture Diagram**
```
┌─────────────────────────────────────────────────────────────┐
│ main_image_generation.py (EXISTS - EXTEND) │
│ ✅ generate_image() (text-to-image) │
│ ✅ generate_character_image() (character consistency) │
│ 🆕 generate_image_edit() (editing operations) │
│ 🆕 generate_image_upscale() (upscaling) │
│ 🆕 generate_image_to_3d() (3D generation) │
│ 🆕 generate_face_swap() (face swapping) │
│ 🆕 generate_image_translate() (translation) │
└──────────────┬──────────────────────────────────────────────┘
│
┌──────────┼──────────┬──────────┐

┌───▼───┐ ┌───▼───┐ ┌───▼───┐ ┌───▼───┐
│Generate│ │ Edit │ │Upscale│ │Transform│
│Provider│ │Provider│ │Provider│ │Provider│
└───┬───┘ └───┬───┘ └───┬───┘ └───┬───┘

│ 🆕 WaveSpeedEditProvider │
│ 🆕 WaveSpeedUpscaleProvider │
│ 🆕 WaveSpeed3DProvider │
│ 🆕 WaveSpeedFaceSwapProvider │
└─────────────────────────────────────────┘
```
### **Key Reusability Principles**
1. **Reuse Existing Infrastructure**
- Extend `main_image_generation.py` (don't duplicate)
- Reuse `ImageGenerationProvider` protocol pattern
- Reuse validation and tracking logic
2. **Consistent Function Signatures**
- All functions follow same pattern: `generate_<operation>()`
- All use same validation/tracking helpers
- All return standardized results
3. **Provider Pattern Extension**
- Create new provider classes following `ImageGenerationProvider` protocol
- Reuse `WaveSpeedClient` for all WaveSpeed operations
- Consistent error handling across providers
---
## 📐 Reusable Code Patterns
### **Pattern 1: Extend Existing Unified Entry Point** ✅
#### **Current Structure** (EXISTS)
```python
# backend/services/llm_providers/main_image_generation.py
def generate_image(
prompt: str,
options: Optional[Dict[str, Any]] = None,
user_id: Optional[str] = None
) -> ImageGenerationResult:
"""Generate image with pre-flight validation."""
# 1. Pre-flight validation
if user_id:
validate_image_generation_operations(...)
# 2. Select provider
provider_name = _select_provider(options.get("provider"))
provider = _get_provider(provider_name)
# 3. Generate
result = provider.generate(image_options)
# 4. Track usage
if user_id and result:
track_image_usage(...)
return result
```
#### **Proposed Extensions** (REUSABLE PATTERN)
```python
# backend/services/llm_providers/main_image_generation.py
# REUSE: Common validation helper
def _validate_image_operation(
user_id: Optional[str],
operation_type: str,
num_operations: int = 1
) -> None:
"""Reusable pre-flight validation for all image operations."""
if not user_id:
logger.warning("No user_id provided - skipping validation")
return
from services.database import get_db
from services.subscription import PricingService
from services.subscription.preflight_validator import validate_image_generation_operations
db = next(get_db())
try:
pricing_service = PricingService(db)
validate_image_generation_operations(
pricing_service=pricing_service,
user_id=user_id,
num_images=num_operations
)
finally:
db.close()
# REUSE: Common usage tracking helper
def _track_image_usage(
user_id: str,
provider: str,
model: str,
operation_type: str,
result_bytes: bytes,
cost: float,
metadata: Optional[Dict[str, Any]] = None
) -> None:
"""Reusable usage tracking for all image operations."""
# ... (extract from existing generate_image function)
# NEW: Extend for editing operations
def generate_image_edit(
image_base64: str,
prompt: str,
operation: str = "general_edit",
model: Optional[str] = None,
options: Optional[Dict[str, Any]] = None,
user_id: Optional[str] = None
) -> ImageGenerationResult:
"""Generate edited image - REUSES validation and tracking."""
# 1. Reuse validation
_validate_image_operation(user_id, "image-edit")
# 2. Get provider (extend to support editing providers)
provider = _get_edit_provider(model or "wavespeed")
# 3. Generate edit
result = provider.edit(image_base64, prompt, operation, options)
# 4. Reuse tracking
if user_id and result:
_track_image_usage(
user_id=user_id,
provider=result.provider,
model=result.model,
operation_type="image-edit",
result_bytes=result.image_bytes,
cost=result.metadata.get("estimated_cost", 0.0),
metadata=result.metadata
)
return result
```
#### **Benefits**
- ✅ **Reuses existing infrastructure** - no duplication
- ✅ **Consistent patterns** - all operations follow same flow
- ✅ **Easy to extend** - add new operations by following pattern
- ✅ **Single source of truth** - validation/tracking in one place
---
### **Pattern 2: Reusable Validation & Tracking Helpers** ✅
#### **Current Implementation** (EXISTS in `main_image_generation.py`)
```python
# Pre-flight validation (lines 58-83)
if user_id:
db = next(get_db())
try:
pricing_service = PricingService(db)
validate_image_generation_operations(...)
finally:
db.close()
# Usage tracking (lines 117-265)
if user_id and result and result.image_bytes:
# ... tracking logic
```
#### **Proposed Refactoring** (EXTRACT FOR REUSABILITY)
```python
# backend/services/llm_providers/main_image_generation.py
# EXTRACT: Reusable validation function
def _validate_and_track_image_operation(
user_id: Optional[str],
operation_type: str,
provider: str,
model: str,
result: Optional[ImageGenerationResult],
num_operations: int = 1
) -> None:
"""
REUSABLE helper for validation and tracking.
Used by all image operation functions.
"""
# Pre-flight validation
if user_id:
_validate_image_operation(user_id, operation_type, num_operations)
# Post-generation tracking
if user_id and result and result.image_bytes:
_track_image_usage(
user_id=user_id,
provider=provider,
model=model,
operation_type=operation_type,
result_bytes=result.image_bytes,
cost=result.metadata.get("estimated_cost", 0.0) if result.metadata else 0.0,
metadata=result.metadata
)
# REFACTOR: Existing generate_image to use helper
def generate_image(...) -> ImageGenerationResult:
"""Generate image - now uses reusable helpers."""
# ... provider selection and generation ...
# REUSE: Validation and tracking
_validate_and_track_image_operation(
user_id=user_id,
operation_type="text-to-image",
provider=provider_name,
model=result.model,
result=result
)
return result
```
#### **Benefits**
- ✅ **DRY Principle** - validation/tracking logic in one place
- ✅ **Consistent behavior** - all operations use same validation
- ✅ **Easy maintenance** - change validation logic once, affects all
- ✅ **Testable** - helpers can be tested independently
---
### **Pattern 3: Extend Provider Pattern for Reusability** ✅
#### **Current Structure** (EXISTS)
```python
# backend/services/llm_providers/image_generation/base.py
class ImageGenerationProvider(Protocol):
"""Protocol for image generation providers."""
def generate(self, options: ImageGenerationOptions) -> ImageGenerationResult:
...
# backend/services/llm_providers/image_generation/wavespeed_provider.py
class WaveSpeedImageProvider(ImageGenerationProvider):
"""WaveSpeed AI image generation provider."""
SUPPORTED_MODELS = {
"ideogram-v3-turbo": {...},
"qwen-image": {...}
}
def generate(self, options: ImageGenerationOptions) -> ImageGenerationResult:
# ... implementation
```
#### **Proposed Extension** (REUSE PATTERN)
```python
# backend/services/llm_providers/image_generation/base.py
# EXTEND: Add editing protocol
class ImageEditProvider(Protocol):
"""Protocol for image editing providers."""
def edit(
self,
image_base64: str,
prompt: str,
operation: str,
options: ImageEditOptions
) -> ImageGenerationResult:
...
# NEW: Reuse WaveSpeed client pattern
# backend/services/llm_providers/image_generation/wavespeed_edit_provider.py
class WaveSpeedEditProvider(ImageEditProvider):
"""WaveSpeed AI image editing provider - REUSES client."""
# REUSE: Same client initialization
def __init__(self, api_key: Optional[str] = None):
self.client = WaveSpeedClient(api_key=api_key) # REUSE
# REUSE: Model registry pattern
SUPPORTED_MODELS = {
"qwen-edit": {
"model_path": "wavespeed-ai/qwen-image/edit",
"cost": 0.02,
},
"step1x-edit": {
"model_path": "wavespeed-ai/step1x-edit",
"cost": 0.03,
},
# ... 12 editing models
}
def edit(
self,
image_base64: str,
prompt: str,
operation: str,
options: ImageEditOptions
) -> ImageGenerationResult:
"""Edit image - REUSES client pattern."""
model_info = self.SUPPORTED_MODELS.get(options.model)
if not model_info:
raise ValueError(f"Unsupported model: {options.model}")
# REUSE: Same client call pattern
image_bytes = self.client.edit_image(
model=model_info["model_path"],
image_base64=image_base64,
prompt=prompt,
**options.to_dict()
)
# REUSE: Same result format
return ImageGenerationResult(
image_bytes=image_bytes,
width=options.width,
height=options.height,
provider="wavespeed",
model=options.model,
metadata={"cost": model_info["cost"]}
)
```
#### **Benefits**
- ✅ **Reuses existing protocol pattern** - consistent interface
- ✅ **Reuses WaveSpeedClient** - no duplicate client code
- ✅ **Reuses model registry pattern** - easy to add models
- ✅ **Reuses result format** - consistent return types
---
### **Pattern 4: Reusable Model Registry** (ENHANCE EXISTING)
#### **Current Pattern** (EXISTS in providers)
```python
# WaveSpeedImageProvider.SUPPORTED_MODELS
SUPPORTED_MODELS = {
"ideogram-v3-turbo": {
"name": "Ideogram V3 Turbo",
"cost_per_image": 0.10,
"max_resolution": (1024, 1024),
},
"qwen-image": {...}
}
```
#### **Proposed Enhancement** (CENTRALIZE FOR REUSABILITY)
```python
# backend/services/image_studio/model_registry.py
@dataclass
class ImageModel:
"""Model metadata - REUSES existing provider pattern."""
id: str
name: str
provider: str
model_path: str
cost: float
category: str # "generation", "editing", "upscaling", "3d", "face-swap"
capabilities: List[str]
max_resolution: Optional[tuple[int, int]] = None
class ImageModelRegistry:
"""Centralized registry - AGGREGATES from providers."""
# REUSE: Extract from existing providers
MODELS: Dict[str, ImageModel] = {
# Generation (from WaveSpeedImageProvider)
"ideogram-v3-turbo": ImageModel(
id="ideogram-v3-turbo",
name="Ideogram V3 Turbo",
provider="wavespeed",
model_path="ideogram-ai/ideogram-v3-turbo",
cost=0.10, # From SUPPORTED_MODELS
category="generation",
capabilities=["text-to-image"],
),
# Editing (NEW - follows same pattern)
"qwen-edit": ImageModel(
id="qwen-edit",
name="Qwen Image Edit",
provider="wavespeed",
model_path="wavespeed-ai/qwen-image/edit",
cost=0.02,
category="editing",
capabilities=["image-edit", "style-transfer"],
),
# ... 40+ models
}
@classmethod
def get_model(cls, model_id: str) -> Optional[ImageModel]:
"""Get model by ID - REUSABLE across all services."""
return cls.MODELS.get(model_id)
@classmethod
def list_by_category(cls, category: str) -> List[ImageModel]:
"""List models by category - REUSABLE query."""
return [m for m in cls.MODELS.values() if m.category == category]
@classmethod
def get_cost(cls, model_id: str) -> float:
"""Get cost for model - REUSABLE cost lookup."""
model = cls.get_model(model_id)
return model.cost if model else 0.0
```
#### **Benefits**
- ✅ **Reuses provider model definitions** - single source of truth
- ✅ **Reusable queries** - all services can use same registry
- ✅ **Cost calculation** - centralized cost lookup
- ✅ **Frontend integration** - single endpoint for model list
---
### **Pattern 5: Usage Tracking**
#### **Structure**
```python

log_api_usage(user_id, provider, model_name, operation_type, cost, image_bytes)
db.commit()
return {
"previous_calls": previous_count,
"current_calls": usage_summary.image_calls,
"cost": cost,
"total_cost": usage_summary.image_cost,
}
finally:
db.close()
```
#### **Benefits**
- Consistent with video tracking
- Centralized cost calculation
- Automatic usage logging
- Real-time limit checking
---
### **Pattern 6: Service Layer - Reuse Existing Entry Point** ✅
#### **Current Implementation** (MIXED USAGE)
```python
# CreateStudioService - Uses providers directly (NOT using main_image_generation.py)
# Other services (YouTube, Podcast) - Use main_image_generation.py ✅
```
#### **Proposed Refactoring** (REUSE UNIFIED ENTRY)
```python
# backend/services/image_studio/create_service.py
class CreateStudioService:
"""Service for Create Studio - REUSES unified entry point."""
async def generate(
self,
request: CreateStudioRequest,
user_id: Optional[str] = None,
) -> Dict[str, Any]:
"""Generate image - REUSES main_image_generation.py."""
# REUSE: Existing unified entry point
from services.llm_providers.main_image_generation import generate_image
# Map request to unified format
options = {
"provider": request.provider or "auto",
"model": request.model,
"width": request.width,
"height": request.height,
"negative_prompt": request.negative_prompt,
"guidance_scale": request.guidance_scale,
"steps": request.steps,
"seed": request.seed,
}
# REUSE: Call unified entry point
results = []
for i in range(request.num_variations):
result = generate_image(
prompt=request.prompt,
options=options,
user_id=user_id
)
results.append({
"image_bytes": result.image_bytes,
"width": result.width,
"height": result.height,
"model": result.model,
"metadata": result.metadata,
})
return {
"success": True,
"results": results,
"cost": sum(r["metadata"].get("estimated_cost", 0) for r in results),
}
```
#### **Benefits**
- ✅ **Reuses existing unified entry** - no duplicate validation/tracking
- ✅ **Consistent behavior** - all services use same entry point
- ✅ **Thin service layer** - services focus on business logic
- ✅ **Easy to maintain** - changes in entry point affect all services

### **Key Reusability Principles**
1. **Extend, Don't Duplicate**
- ✅ Extend `main_image_generation.py` (don't create new file)
- ✅ Extend `ImageGenerationProvider` protocol (don't create new base)
- ✅ Reuse `WaveSpeedClient` (don't duplicate client code)
2. **Extract Common Logic**
- ✅ Extract validation into reusable helper
- ✅ Extract tracking into reusable helper
- ✅ Extract cost calculation into reusable helper
3. **Consistent Patterns**
- ✅ All operations follow same function signature pattern
- ✅ All operations use same validation/tracking helpers
- ✅ All providers follow same protocol pattern
---
## 🔄 Implementation Strategy (REUSE EXISTING)
### **Phase 1: Extract Reusable Helpers** (Week 1)
1. ✅ **Extract validation helper** from `generate_image()` → `_validate_image_operation()`
2. ✅ **Extract tracking helper** from `generate_image()` → `_track_image_operation_usage()`
3. ✅ **Refactor existing functions** to use extracted helpers
4. ✅ **Test** - ensure existing functionality unchanged
### **Phase 2: Extend for Editing** (Week 2)
1. ✅ **Add `ImageEditProvider` protocol** to `base.py`
2. ✅ **Create `WaveSpeedEditProvider`** following existing provider pattern
3. ✅ **Add `generate_image_edit()`** to `main_image_generation.py` (reuses helpers)
4. ✅ **Refactor `EditStudioService`** to use unified entry point
### **Phase 3: Extend for Upscaling** (Week 3)
1. ✅ **Add `ImageUpscaleProvider` protocol** to `base.py`

## 📋 Reusable Code Examples
### **Example 1: Adding a New Editing Model** (REUSES PATTERNS)
```python
# 1. Add to WaveSpeedEditProvider (REUSES existing pattern)
# backend/services/llm_providers/image_generation/wavespeed_edit_provider.py
class WaveSpeedEditProvider(ImageEditProvider):
SUPPORTED_MODELS = {
# ... existing models ...
"new-edit-model": { # 🆕 NEW MODEL
"model_path": "wavespeed-ai/new-edit-model",
"cost": 0.05,
"max_resolution": (2048, 2048),
}
}
def edit(self, image_base64: str, prompt: str, ...):
# REUSES: Same client call pattern
model_info = self.SUPPORTED_MODELS.get(options.model)
image_bytes = self.client.edit_image(
model=model_info["model_path"],
image_base64=image_base64,
prompt=prompt,
**options.to_dict()
)
# REUSES: Same result format
return ImageGenerationResult(...)
# 2. Register in model registry (REUSES registry pattern)
# backend/services/image_studio/model_registry.py
ImageModelRegistry.MODELS["new-edit-model"] = ImageModel(
id="new-edit-model",
name="New Edit Model",
provider="wavespeed",
model_path="wavespeed-ai/new-edit-model",
cost=0.05, # From provider SUPPORTED_MODELS
category="editing",
capabilities=["image-edit"],
)
# 3. Use in service (REUSES unified entry)
# backend/services/image_studio/edit_service.py
from services.llm_providers.main_image_generation import generate_image_edit
result = generate_image_edit(
image_base64=image,
prompt=prompt,
model="new-edit-model", # 🆕 Just specify model ID
user_id=user_id,
)
# ✅ Validation, tracking, error handling all handled automatically
```
### **Example 2: Adding a New Operation Type** (REUSES HELPERS)
```python
# In main_image_generation.py (EXTEND existing file)
def generate_face_swap(
source_image_base64: str,
target_image_base64: str,
model: str = "wavespeed-ai/image-face-swap",
options: Optional[Dict[str, Any]] = None,
user_id: Optional[str] = None
) -> ImageGenerationResult:
"""
Face swap operation - REUSES validation and tracking helpers.
"""
# 1. REUSE: Validation helper
_validate_image_operation(user_id, "face-swap")
# 2. Get provider (REUSES provider pattern)
provider = _get_face_swap_provider(model)
# 3. Perform operation
result = provider.face_swap(
source_image_base64=source_image_base64,
target_image_base64=target_image_base64,
model=model,
options=options or {}
)
# 4. REUSE: Tracking helper
if user_id and result:
_track_image_operation_usage(
user_id=user_id,
provider=result.provider,
model=result.model,
operation_type="face-swap",
result_bytes=result.image_bytes,
cost=result.metadata.get("estimated_cost", 0.0),
metadata=result.metadata
)
return result
```
### **Example 3: Refactoring Existing Service** (REUSE UNIFIED ENTRY)
```python
# BEFORE: CreateStudioService uses providers directly
class CreateStudioService:
async def generate(self, request, user_id):
# ... validation logic ...
provider = self._get_provider_instance(provider_name)
result = provider.generate(options)
# ... tracking logic ...
return result
# AFTER: CreateStudioService REUSES unified entry
class CreateStudioService:
async def generate(self, request, user_id):
# REUSE: Unified entry point (validation + tracking included)
from services.llm_providers.main_image_generation import generate_image
results = []
for i in range(request.num_variations):
result = generate_image( # ✅ All validation/tracking handled
prompt=request.prompt,
options={...},
user_id=user_id
)
results.append(result)
return {"results": results}
```
---
## ✅ Benefits of Reusable Architecture
1. **✅ Reuses Existing Code**: Builds on `main_image_generation.py` (no duplication)
2. **✅ DRY Principle**: Validation and tracking extracted into reusable helpers
3. **✅ Consistent Patterns**: All operations follow same proven pattern
4. **✅ Easy to Extend**: Add new operations by following existing pattern
5. **✅ Single Source of Truth**: Model registry aggregates from providers
6. **✅ Maintainable**: Changes in helpers affect all operations
7. **✅ Testable**: Helpers can be tested independently
8. **✅ Backward Compatible**: Existing code continues to work
---
## 🎯 Next Steps
1. **✅ Review existing `main_image_generation.py`** - understand current implementation
2. **✅ Extract reusable helpers** - validation and tracking functions
3. **✅ Extend for editing operations** - add `generate_image_edit()` following pattern
4. **✅ Create model registry** - aggregate models from all providers
5. **✅ Refactor services** - make them use unified entry point
6. **✅ Add new operations** - 3D, face swap, translation following same pattern

## 🔑 Key Differences to Note
### **1. Operation Types**
- **Video**: `text-to-video`, `image-to-video`
- **Image**: `text-to-image`, `image-edit`, `image-upscale`, `image-to-3d`, `face-swap`, etc.
### **2. Return Formats**
- **Video**: Always returns `video_bytes`
- **Image**: Returns `image_bytes` (but may also return 3D models, etc.)
### **3. Cost Calculation**
- **Video**: Based on duration, resolution
- **Image**: Based on model, operation type, resolution
### **4. Usage Tracking**
- **Video**: Tracks `video_calls`, `video_cost`
- **Image**: Tracks `stability_calls`, `image_edit_calls`, etc. based on operation type
---
## 📝 Checklist for Adding New Model (REUSABLE PATTERN)
### **Step 1: Add to Provider** (REUSES existing pattern)
- [ ] Add model to provider's `SUPPORTED_MODELS` dict
```python
# In WaveSpeedEditProvider
SUPPORTED_MODELS["new-model"] = {
"model_path": "wavespeed-ai/new-model",
"cost": 0.05,
}
```
### **Step 2: Register in Model Registry** (REUSES registry)
- [ ] Add to `ImageModelRegistry.MODELS`
```python
ImageModelRegistry.MODELS["new-model"] = ImageModel(
id="new-model",
provider="wavespeed",
model_path="wavespeed-ai/new-model",
cost=0.05, # From provider
category="editing",
)
```
### **Step 3: Use in Service** (REUSES unified entry)
- [ ] Call unified entry point (validation/tracking automatic)
```python
result = generate_image_edit(
model="new-model", # ✅ Just specify model ID
image_base64=image,
prompt=prompt,
user_id=user_id,
)
```
### **Key Reusability Points**
- ✅ **No new validation code** - reuses `_validate_image_operation()`
- ✅ **No new tracking code** - reuses `_track_image_operation_usage()`
- ✅ **No new provider base** - follows `ImageEditProvider` protocol
- ✅ **No new client code** - reuses `WaveSpeedClient`
- ✅ **Consistent pattern** - same as existing models
---
## 🔄 Reusability Quick Reference
### **Existing Code to Reuse**
- ✅ `main_image_generation.py` - Extend this file (don't create new)
- ✅ `ImageGenerationProvider` protocol - Extend this pattern
- ✅ `WaveSpeedClient` - Reuse for all WaveSpeed operations
- ✅ Validation logic - Extract to helper
- ✅ Tracking logic - Extract to helper
### **Pattern to Follow**
```python
# 1. Extract helpers from existing code
def _validate_image_operation(...): # Extract from generate_image()
def _track_image_operation_usage(...): # Extract from generate_image()
# 2. Extend existing file
def generate_image_edit(...): # Add to main_image_generation.py
_validate_image_operation(...) # REUSE
result = provider.edit(...)
_track_image_operation_usage(...) # REUSE
return result
# 3. Extend provider protocol
class ImageEditProvider(Protocol): # Add to base.py
def edit(...) -> ImageGenerationResult: ...
# 4. Create provider following pattern
class WaveSpeedEditProvider(ImageEditProvider):
def __init__(self):
self.client = WaveSpeedClient() # REUSE client
def edit(...):
return self.client.edit_image(...) # REUSE client
```

# Image Studio Editing - Completion Summary
**Date**: Current Session
**Status**: ✅ **Backend Complete** - Ready for Frontend Integration
**Progress**: 5 Models Integrated, APIs Ready, Auto-Detection Implemented
---
## ✅ Completed Backend Implementation
### **1. Model Integration** ✅ (5/14 Models)
**Integrated Models**:
1. ✅ **Qwen Image Edit** ($0.02) - Basic, single-image
2. ✅ **Qwen Image Edit Plus** ($0.02) - Multi-image, ControlNet
3. ✅ **Google Nano Banana Pro Edit Ultra** ($0.15-0.18) - 4K/8K, premium
4. ✅ **Bytedance Seedream V4.5 Edit** ($0.04) - Reference-faithful, 4K
5. ✅ **FLUX Kontext Pro** ($0.04) - Typography, guidance scale
**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
---

def edit(self, image_base64: str, prompt: str, operation: str, options: ImageEditOptions) -> ImageGenerationResult:
# ✅ REUSES same client call pattern
model_info = self.SUPPORTED_MODELS.get(options.model)
image_bytes = self.client.edit_image(
model=model_info["model_path"],
image_base64=image_base64,
prompt=prompt,
**options.to_dict()
)
# ✅ REUSES same result format
return ImageGenerationResult(...)
```
---
### **Step 4: Add generate_image_edit() Function** (Day 4)
**File**: `backend/services/llm_providers/main_image_generation.py`
**Action**: Add unified entry point for editing operations

- ✅ **Error handling** - Consistent error patterns
**Implementation**:
```python
def generate_image_edit(
image_base64: str,
prompt: str,
operation: str = "general_edit",
model: Optional[str] = None,
options: Optional[Dict[str, Any]] = None,
user_id: Optional[str] = None
) -> ImageGenerationResult:
"""
Generate edited image - REUSES validation and tracking helpers.
Args:
image_base64: Base64-encoded input image
prompt: Edit instruction prompt
operation: Type of edit operation
model: Model ID to use (default: auto-select)
options: Additional options (mask, negative_prompt, etc.)
user_id: User ID for validation and tracking
Returns:
ImageGenerationResult with edited image
"""
# 1. REUSE: Validation helper
_validate_image_operation(
user_id=user_id,
operation_type="image-edit",

log_prefix="[Image Edit]"
)
# 2. Get provider (REUSES provider pattern)
provider = _get_edit_provider(model or "wavespeed")
# 3. Prepare options
edit_options = ImageEditOptions(
image_base64=image_base64,
prompt=prompt,
operation=operation,
**options or {}
)
# 4. Edit
result = provider.edit(edit_options)
# 5. REUSE: Tracking helper
if user_id and result and result.image_bytes:
_track_image_operation_usage(
user_id=user_id,
provider=result.provider,
model=result.model,
operation_type="image-edit",

cost=result.metadata.get("estimated_cost", 0.0),
prompt=prompt,
endpoint="/image-generation/edit",
metadata=result.metadata,
log_prefix="[Image Edit]"
)
return result
```
---
### **Step 5: Add Provider Selection Helper** (Day 4)
**File**: `backend/services/llm_providers/main_image_generation.py`
**Action**: Add `_get_edit_provider()` helper following `_get_provider()` pattern
```python
def _get_edit_provider(provider_name: str):
"""Get editing provider instance.
Args:
provider_name: Provider name ("wavespeed", "stability", etc.)
Returns:
ImageEditProvider instance
"""
if provider_name == "wavespeed":
return WaveSpeedEditProvider()
elif provider_name == "stability":
# Keep existing Stability editing support
return StabilityEditProvider() # If exists, or wrap existing
else:
raise ValueError(f"Unknown edit provider: {provider_name}")
```
---
### **Step 6: Refactor EditStudioService** (Day 5)
**File**: `backend/services/image_studio/edit_service.py`
**Action**: Update to use unified `generate_image_edit()` entry point
**Changes**:
- ✅ **Remove direct provider calls** - Use unified entry point
- ✅ **Keep existing operations** - Stability AI operations still work
- ✅ **Add WaveSpeed model selection** - New models available
- ✅ **Maintain backward compatibility** - Existing API unchanged
**Implementation**:
```python
# In EditStudioService.process_edit()
# For WaveSpeed models
if request.provider == "wavespeed" or (request.provider is None and request.model and request.model.startswith("wavespeed")):
from services.llm_providers.main_image_generation import generate_image_edit
result = generate_image_edit(
image_base64=request.image_base64,
prompt=request.prompt or "",
operation=request.operation,
model=request.model,
options={
"mask_base64": request.mask_base64,
"negative_prompt": request.negative_prompt,
# ... other options
},
user_id=user_id
)
image_bytes = result.image_bytes
else:
# Keep existing Stability AI editing logic
image_bytes = await self._handle_stability_edit(...)
```
---
### **Step 7: Update API Endpoint** (Day 5)
**File**: `backend/routers/image_studio.py`
**Action**: Add `model` parameter to edit endpoint
**Changes**:
- ✅ Add `model` parameter to request schema
- ✅ Pass model to `EditStudioService`
- ✅ Maintain backward compatibility (model optional)
---
### **Step 8: Frontend Model Selector** (Day 6-7)
**File**: `frontend/src/components/ImageStudio/EditStudio.tsx`
**Action**: Add model selection UI
**Features**:
- ✅ **Model Dropdown** - List all 14 editing models
- ✅ **Cost Display** - Show cost per model
- ✅ **Quality Tiers** - Group by Budget/Mid/Premium
- ✅ **Smart Recommendations** - Auto-suggest based on operation type
- ✅ **Side-by-Side Comparison** - Compare different models (optional)
**UI Components**:
```tsx
<ModelSelector
models={editingModels}
selectedModel={selectedModel}
onModelChange={setSelectedModel}
showCost={true}
showQuality={true}
recommendations={getRecommendations(operation)}
/>
```
---
### **Step 9: Testing & Verification** (Day 8-10)
**Test Cases**:
1. ✅ **All 14 models work** - Test each model with sample edits
2. ✅ **Validation works** - Pre-flight validation for editing
3. ✅ **Tracking works** - Usage tracking for editing operations
4. ✅ **Error handling** - Invalid models, API failures, etc.
5. ✅ **Backward compatibility** - Existing Stability editing still works
6. ✅ **Frontend integration** - Model selector works correctly
7. ✅ **Cost calculation** - Correct costs tracked per model

# 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

---
## 🎯 Core Requirements
### **1. Model Selection UI**
#### **1.1 Model Selector Component**
- **Location**: Edit Studio sidebar or main panel
- **Type**: Dropdown/Select with search capability
- **Display**:
- Model name
- Cost per edit
- Quality tier badge (Budget/Mid/Premium)

- **Reason**: Show why this model was selected (e.g., "Best quality for 4K images")
### **2.3 Fallback Logic**
- **If no model matches**: Use first available model
- **If model unavailable**: Show error with alternative suggestions
- **If user has insufficient credits**: Suggest budget alternative
---
## 📚 User Education
### **3.1 Model Information Cards**
Each model should display:
```
┌─────────────────────────────────────┐

# Image Studio Face Swap - Implementation Plan
**Date**: Current Session
**Status**: ✅ **COMPLETE** - Backend & Frontend Implemented
**Priority**: ⭐ **HIGH PRIORITY** - **COMPLETED**
---
## 🎯 Overview
Implement Face Swap Studio for Image Studio, following the same reusable architecture pattern as Editing feature.
**Models Integrated** (4 models): ✅ **COMPLETE**
1. ✅ **Image Face Swap Pro** ($0.025) - Enhanced quality, realistic blending
2. ✅ **Image Head Swap** ($0.025) - Full head replacement (face + hair + outline)
3. ✅ **Akool Image Face Swap** ($0.16) - Multi-face swapping (up to 5 faces)
4. ✅ **InfiniteYou** ($0.03) - High-quality identity preservation (ByteDance zero-shot)
---
## 🏗️ Architecture (REUSES EXISTING PATTERNS)
### **Phase 1: Foundation** (Same as Editing)
1. **Protocol & Options**
- Create `FaceSwapOptions` dataclass in `base.py`
- Create `FaceSwapProvider` protocol
- Follow same pattern as `ImageEditProvider`
2. **Unified Entry Point**
- Add `generate_face_swap()` to `main_image_generation.py`
- **REUSE**: `_validate_image_operation()` helper
- **REUSE**: `_track_image_operation_usage()` helper
- Follow same pattern as `generate_image_edit()`
3. **Provider Implementation**
- Create `WaveSpeedFaceSwapProvider` in `wavespeed_face_swap_provider.py`
- **REUSE**: `WaveSpeedClient` for API calls
- **REUSE**: Polling and download patterns from editing
---

model: Optional[str] = None
target_face_index: Optional[int] = None # For multi-face images
target_gender: Optional[str] = None # "all", "female", "male"
extra: Optional[Dict[str, Any]] = None
class FaceSwapProvider(Protocol):
def swap_face(self, options: FaceSwapOptions) -> ImageGenerationResult:
...
```
---
### **Step 2: WaveSpeedFaceSwapProvider Structure** ✅ **COMPLETE**

db = next(get_db())
try:
pricing_service = PricingService(db)
validate_image_generation_operations(...)
finally:
db.close()
# Tracking logic duplicated in both functions
if user_id and result:
db_track = next(get_db())
try:
# ... 150+ lines of tracking logic ...
finally:
db_track.close()
```
### **After (Reusable Helpers)**
```python
# Validation - one line call
_validate_image_operation(user_id=user_id, operation_type="image-generation", ...)

# Image Studio Unified Entry Point Refactoring Summary
**Status**: ✅ **COMPLETED**
**Date**: Current Session
**Goal**: Ensure all Image Studio features use unified entry point and reusable helpers
---
## 🎯 Objectives
1. ✅ Refactor `CreateStudioService` to use unified entry point (`main_image_generation.generate_image()`)
2. ✅ Refactor `UpscaleStudioService` to use validation helper
3. ✅ Review `EditStudioService` (uses different validator - intentional)
4. ✅ Ensure no regressions - maintain all existing functionality
---
## ✅ Completed Refactoring
### 1. **CreateStudioService** ✅
**File**: `backend/services/image_studio/create_service.py`
**Changes**:
- ✅ **Removed direct provider usage** - No longer instantiates providers directly
- ✅ **Uses unified entry point** - Now calls `main_image_generation.generate_image()`
- ✅ **Uses validation helper** - Replaced duplicated validation with `_validate_image_operation()`
- ✅ **Automatic tracking** - Usage tracking now handled by unified entry point
- ✅ **Removed unused imports** - Cleaned up `os` import and provider classes
**Before**:
```python
# Direct provider instantiation
provider = self._get_provider_instance(provider_name)
result = provider.generate(options)
# Duplicated validation (25 lines)
if user_id:
db = next(get_db())
# ... validation logic ...
```
**After**:
```python
# Unified entry point (handles validation, provider selection, tracking)
result = generate_image(
prompt=prompt,
options=options,
user_id=user_id
)
# Reusable validation helper
_validate_image_operation(
user_id=user_id,
operation_type="create-studio-generation",
num_operations=request.num_variations,
log_prefix="[Create Studio]"
)
```
**Benefits**:
- ✅ **Consistent validation** - Uses same validation as other image operations
- ✅ **Automatic tracking** - Usage tracking handled automatically
- ✅ **Reduced code** - Removed ~50 lines of duplicated code
- ✅ **Better error handling** - Unified error handling patterns
- ✅ **Easier maintenance** - Changes to validation/tracking affect all operations
---
### 2. **UpscaleStudioService** ✅
**File**: `backend/services/image_studio/upscale_service.py`
**Changes**:
- ✅ **Uses validation helper** - Replaced duplicated validation with `_validate_image_operation()`
- ✅ **Consistent logging** - Uses same log prefix pattern
**Before**:
```python
if user_id:
from services.database import get_db
from services.subscription import PricingService
from services.subscription.preflight_validator import validate_image_upscale_operations
db = next(get_db())
try:
pricing_service = PricingService(db)
validate_image_upscale_operations(...)
finally:
db.close()
```
**After**:
```python
if user_id:
from services.llm_providers.main_image_generation import _validate_image_operation
_validate_image_operation(
user_id=user_id,
operation_type="image-upscale",
num_operations=1,
log_prefix="[Upscale Studio]"
)
```
**Benefits**:
- ✅ **Reduced code** - Removed ~10 lines of duplicated validation
- ✅ **Consistent validation** - Uses same validation helper as other operations
- ✅ **Easier maintenance** - Validation changes affect all operations
---
### 3. **EditStudioService** ✅ (Reviewed - No Changes Needed)
**File**: `backend/services/image_studio/edit_service.py`
**Status**: ✅ **Intentionally uses different validator**
**Reason**:
- Editing operations use `validate_image_editing_operations()`
- This is different from `validate_image_generation_operations()`
- Editing may have different subscription limits/costs
- This is intentional and correct
**Note**: If we want to unify this later, we would need to:
1. Make `_validate_image_operation()` support different validator types
2. Or create a separate helper for editing operations
3. For now, keeping it separate is fine as it uses the correct validator
---
## 📊 Code Reduction Summary
| Service | Before | After | Reduction |
|---------|--------|-------|-----------|
| `CreateStudioService` | ~460 lines | ~410 lines | **~50 lines** |
| `UpscaleStudioService` | ~155 lines | ~145 lines | **~10 lines** |
| **Total** | **~615 lines** | **~555 lines** | **~60 lines** |
**Lines Removed**: ~60 lines of duplicated validation/tracking code
---
