## 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

**Tests:**
1. ✅ Valid text model accepted (gpt-4o-mini)
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

**Result:** All validation logic working perfectly

---

### 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

---

### Test 5: REST API Serializer
**Purpose:** Verify API serialization works

**Tests:**
1. ✅ Single model serialization
2. ✅ Serialize all text models (5 models)
3. ✅ Serialize all image models (2 models)
4. ✅ Text model pricing fields (input_cost_per_1m, output_cost_per_1m)
5. ✅ Image model pricing fields (cost_per_image)
6. ✅ Image model sizes field (valid_sizes array)
7. ✅ Pricing display field

**Result:** All serialization working correctly with proper field names

---

### Test 6: End-to-End Integration
**Purpose:** Verify complete workflows work end-to-end

**Tests:**
1. ✅ Complete text generation workflow:
   - Model validation
   - OpenAI cost calculation ($0.000525)
   - Credit calculation (20 credits)
   - Revenue calculation ($0.2000)
   - Profit margin (99.7%)

2. ✅ Complete image generation workflow:
   - Model validation
   - Size validation
   - Cost calculation ($0.0400 per image)

3. ✅ All 7 active models verified (5 text + 2 image)

4. ✅ Database query performance for all models

**Result:** Complete workflows work perfectly from validation to cost calculation

## 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
- `GET /api/v1/billing/ai/models/<id>/` - Get specific model

## Cost Examples

### Text Generation (gpt-4o-mini)
- **OpenAI Cost:** 1000 input + 500 output tokens = $0.000450
- **Credits Charged:** 10 credits ($0.10)
- **Profit Margin:** 99.6%

### Image Generation (dall-e-3)
- **OpenAI Cost:** 1 image (1024x1024) = $0.0400
- **Credits:** Charged by customer configuration

---

## 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)
```
