## Test Details
|
|
|
|
### Test 1: Model Instance Methods
|
|
**Purpose:** Verify AIModelConfig model methods work correctly
|
|
|
|
**Tests:**
|
|
1. ✅ `get_cost_for_tokens(2518, 242)` → $0.000523
|
|
2. ✅ `get_cost_for_images(3)` → $0.0800
|
|
3. ✅ `validate_size('1024x1024')` → True
|
|
4. ✅ `validate_size('512x512')` → False (dall-e-3 doesn't support)
|
|
5. ✅ Display format correct
|
|
|
|
**Result:** All model methods calculate costs accurately
|
|
|

|
|
|
|
### Test 2: AI Core Cost Calculations
|
|
**Purpose:** Verify ai_core.py uses database correctly
|
|
|
|
**Tests:**
|
|
1. ✅ Text model cost calculation (1000 input + 500 output = $0.000450)
|
|
2. ✅ Image model cost calculation (dall-e-3 = $0.0400)
|
|
3. ✅ Fallback mechanism works (non-existent model uses constants)
|
|
4. ✅ All 5 text models consistent with database
|
|
5. ✅ All 2 image models consistent with database
|
|
|
|
**Result:** AICore.calculate_cost() works perfectly with database queries and fallback
|
|
|

|
|
### Test 3: Validators
|
|
**Purpose:** Verify model and size validation works
|
|
|
|

|
|
2. ✅ Invalid text model rejected (fake-gpt-999)
|
|
3. ✅ Valid image model accepted (dall-e-3)
|
|
4. ✅ Invalid image model rejected (fake-dalle)
|
|
5. ✅ Inactive model rejected (gpt-image-1)
|
|
6. ✅ Valid size accepted (1024x1024 for dall-e-3)
|
|
7. ✅ Invalid size rejected (512x512 for dall-e-3)
|
|
8. ✅ All 5 active text models validate
|
|
9. ✅ All 2 active image models validate
|
|
|
|

### Test 4: Credit Calculation Integration
|
|
**Purpose:** Verify credit system integrates with AI costs
|
|
|
|
**Tests:**
|
|
1. ✅ Clustering credits: 2760 tokens → 19 credits
|
|
2. ✅ Profit margin: 99.7% (OpenAI cost $0.000523, Revenue $0.1900)
|
|
3. ✅ Minimum credits enforcement: 15 tokens → 10 credits (minimum)
|
|
4. ✅ High token count: 60,000 tokens → 600 credits
|
|
|
|
**Result:** Credit calculations work correctly with proper profit margins
|
|

|
|
2. ✅ Serialize all text models (5 models)
|
|

|
|
- Model validation
|
|
- OpenAI cost calculation ($0.000525)
|
|

|
|
|
|
2. ✅ Complete image generation workflow:

|
|
- Cost calculation ($0.0400 per image)
|
|
|
|
3. ✅ All 7 active models verified (5 text + 2 image)
|
|
|
|
4. ✅ Database query performance for all models
|

## Implementation Details
|
|
|
|
### Database Schema
|
|
- **Model:** `AIModelConfig`
|
|
- **Fields:** 15 (model_name, display_name, model_type, provider, costs, features, etc.)
|
|
- **Migration:** `0020_create_ai_model_config.py`
|
|
- **Seeded Models:** 9 (7 active, 2 inactive)
|
|
|
|
### Methods Implemented
|
|
```python
|
|
# Text model cost calculation
|
|
AIModelConfig.get_cost_for_tokens(input_tokens, output_tokens) -> Decimal
|
|
|
|
# Image model cost calculation
|
|
AIModelConfig.get_cost_for_images(num_images) -> Decimal
|
|
|
|
# Size validation
|
|
AIModelConfig.validate_size(size) -> bool
|
|
|
|
# Unified cost calculation (in ai_core.py)
|
|
AICore.calculate_cost(model, input_tokens, output_tokens, model_type) -> float
|
|
```
|
|
|
|
### Files Modified (7)
|
|
1. `billing/models.py` - AIModelConfig class (240 lines)
|
|
2. `billing/admin.py` - Admin interface with filters
|
|
3. `ai/ai_core.py` - 3 functions updated with database queries
|
|
4. `ai/validators.py` - 2 functions updated with database queries
|
|
5. `modules/billing/serializers.py` - AIModelConfigSerializer
|
|
6. `modules/billing/views.py` - AIModelConfigViewSet
|
|
7. `business/billing/urls.py` - API routing
|
|
|
|
### REST API Endpoints
|
|
- `GET /api/v1/billing/ai/models/` - List all active models
|
|
- `GET /api/v1/billing/ai/models/?model_type=text` - Filter by type
|
|
- `GET /api/v1/billing/ai/models/?provider=openai` - Filter by provider

## Cost Examples
|
|
|
|
### Text Generation (gpt-4o-mini)
|
|

|
|
- **Credits Charged:** 10 credits ($0.10)
|
|
- **Profit Margin:** 99.6%
|
|
|
|
### Image Generation (dall-e-3)

|
|

|
|
|
## Fallback Safety Mechanism
|
|
|
|
All functions include try/except blocks that:
|
|
1. **Try:** Query database for model config
|
|
2. **Except:** Fall back to constants in `ai/constants.py`
|
|
3. **Result:** System never fails, always returns a valid cost
|
|
|
|
**Example:**
|
|
```python
|
|
try:
|
|
model_config = AIModelConfig.objects.get(model_name=model, is_active=True)
|
|
return model_config.get_cost_for_tokens(input, output)
|
|
except:
|
|
# Fallback to constants
|
|
rates = MODEL_RATES.get(model, {'input': 2.00, 'output': 8.00})
|
|
return calculate_with_rates(rates)
|
|
```
|
