Test Details
Test 1: Model Instance Methods
Purpose: Verify AIModelConfig model methods work correctly
Tests:
- ✅
get_cost_for_tokens(2518, 242)→ $0.000523 - ✅
get_cost_for_images(3)→ $0.0800 - ✅
validate_size('1024x1024')→ True - ✅
validate_size('512x512')→ False (dall-e-3 doesn't support) - ✅ 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:
- ✅ Text model cost calculation (1000 input + 500 output = $0.000450)
- ✅ Image model cost calculation (dall-e-3 = $0.0400)
- ✅ Fallback mechanism works (non-existent model uses constants)
- ✅ All 5 text models consistent with database
- ✅ 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:
- ✅ Valid text model accepted (gpt-4o-mini)
- ✅ Invalid text model rejected (fake-gpt-999)
- ✅ Valid image model accepted (dall-e-3)
- ✅ Invalid image model rejected (fake-dalle)
- ✅ Inactive model rejected (gpt-image-1)
- ✅ Valid size accepted (1024x1024 for dall-e-3)
- ✅ Invalid size rejected (512x512 for dall-e-3)
- ✅ All 5 active text models validate
- ✅ 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:
- ✅ Clustering credits: 2760 tokens → 19 credits
- ✅ Profit margin: 99.7% (OpenAI cost $0.000523, Revenue $0.1900)
- ✅ Minimum credits enforcement: 15 tokens → 10 credits (minimum)
- ✅ 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:
- ✅ Single model serialization
- ✅ Serialize all text models (5 models)
- ✅ Serialize all image models (2 models)
- ✅ Text model pricing fields (input_cost_per_1m, output_cost_per_1m)
- ✅ Image model pricing fields (cost_per_image)
- ✅ Image model sizes field (valid_sizes array)
- ✅ 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:
-
✅ Complete text generation workflow:
- Model validation
- OpenAI cost calculation ($0.000525)
- Credit calculation (20 credits)
- Revenue calculation ($0.2000)
- Profit margin (99.7%)
-
✅ Complete image generation workflow:
- Model validation
- Size validation
- Cost calculation ($0.0400 per image)
-
✅ All 7 active models verified (5 text + 2 image)
-
✅ Database query performance for all models
Result: Complete workflows work perfectly from validation to cost calculation
Features Verified
✅ Database-driven model pricing
✅ Cost calculation for text models (token-based)
✅ Cost calculation for image models (per-image)
✅ Model validation with active/inactive filtering
✅ Image size validation per model
✅ Credit calculation integration
✅ Profit margin calculation (99.7% for text, varies by model)
✅ REST API serialization
✅ Fallback to constants (safety mechanism)
✅ Django Admin interface with filters and bulk actions
✅ Lazy imports (circular dependency prevention)
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
# 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

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:
- Try: Query database for model config
- Except: Fall back to constants in
ai/constants.py - Result: System never fails, always returns a valid cost
Example:
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)
