+
+### Image Generation Credit System
+
+This release implements complete credit deduction, verification, and logging for all 3 image generation models, ensuring consistency with other AI functions in the automation pipeline.
+
+---
+
+### 💰 Credit System for Image Generation
+
+**New Credit Check Method:**
+- Added `CreditService.check_credits_for_image()` in [credit_service.py:307-335](backend/igny8_core/business/billing/services/credit_service.py#L307-L335)
+- Pre-checks if account has sufficient credits before image generation starts
+- Uses `credits_per_image` from AIModelConfig (as configured in admin)
+- Returns required credits or raises `InsufficientCreditsError`
+
+**Pre-Generation Credit Verification:**
+- Added credit check before processing images in [tasks.py:290-319](backend/igny8_core/ai/tasks.py#L290-L319)
+- Checks total credits needed for all images BEFORE starting generation
+- Returns error with `InsufficientCreditsError` if not enough credits
+- Gracefully handles missing model configurations for backward compatibility
+
+**Credit Deduction (Already Existed - Now Verified):**
+- `deduct_credits_for_image()` called after each successful image in [tasks.py:745-770](backend/igny8_core/ai/tasks.py#L745-L770)
+- Fixed cost retrieval to use `result.get('cost')` (was incorrectly using `cost_usd`)
+- Credits per model (from AIModelConfig):
+  - `runware:97@1`: 1 credit/image (basic tier)
+  - `dall-e-3`: 5 credits/image (quality tier)
+  - `google:4@2`: 15 credits/image (premium tier)
+
+---
+
+### 📊 Logging & Notifications
+
+**AITaskLog Integration:**
+- Added AITaskLog logging in [tasks.py:838-875](backend/igny8_core/ai/tasks.py#L838-L875)
+- Records function_name (`generate_images`), account, phase, status, cost
+- Consistent with other AI function logging (clustering, content generation, etc.)
+
+**Notification Integration:**
+- Added notification creation in [tasks.py:877-895](backend/igny8_core/ai/tasks.py#L877-L895)
+- Creates success notifications via `NotificationService.notify_images_complete()`
+- Creates failure notifications via `NotificationService.notify_images_failed()`
+- Same pattern as used in AIEngine for other AI functions
+
+---
+
+### 🔄 Automation Compatibility
+
+**Verified automation flow for image generation:**
+- Stage 6 in automation service calls `process_image_generation_queue` correctly
+- Credit deduction happens inside the task (same as manual image generation)
+- Credits tracked via `_get_credits_used()` and stored in `stage_6_result`
+- Consistent with Stages 1, 2, 4, 5 credit tracking
+
+---
+
+### 📁 Files Changed
+
+| File | Changes |
+|------|---------|
+| `backend/igny8_core/business/billing/services/credit_service.py` | Added `check_credits_for_image()` method |
+| `backend/igny8_core/ai/tasks.py` | Added credit check, AITaskLog logging, notifications |
+
+---
+
+### 📋 Credit Usage Logging Locations
+
+| Table | Purpose |
+|-------|---------|
+| `CreditTransaction` | Financial ledger entry (via `deduct_credits_for_image`) |
+| `CreditUsageLog` | Detailed usage log with model, cost, credits |
+| `AITaskLog` | AI task execution tracking |
+| `Notification` | User notifications for completion/failure |
+
+---

+- Automation Stage 6 (scheduled/manual automation runs)

+Both call `process_image_generation_queue` which handles:
+- Credit checking before generation
+- Credit deduction after each successful image
+- Proper logging to all tables
