# AI Models Database Configuration - Implementation Summary
|
||||
|
||||
**Date Completed:** December 24, 2025
|
||||
**Status:** ✅ **PRODUCTION READY**
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Successfully migrated AI model pricing from hardcoded constants to a dynamic database-driven system. The system now supports real-time model configuration via Django Admin without requiring code deployments.
|
||||
|
||||
---
|
||||
|
||||
## Implementation Phases (All Complete ✅)
|
||||
|
||||
### Phase 1: AIModelConfig Model ✅
|
||||
**File:** `backend/igny8_core/business/billing/models.py`
|
||||
|
||||
Created comprehensive model with:
|
||||
- 15 fields supporting both text and image models
|
||||
- Text model fields: `input_cost_per_1m`, `output_cost_per_1m`, `context_window`, `max_output_tokens`
|
||||
- Image model fields: `cost_per_image`, `valid_sizes` (JSON array)
|
||||
- Capabilities: `supports_json_mode`, `supports_vision`, `supports_function_calling`
|
||||
- Status fields: `is_active`, `is_default`, `sort_order`
|
||||
- Audit trail: `created_at`, `updated_at`, `updated_by`
|
||||
- History tracking via `django-simple-history`
|
||||
|
||||
**Methods:**
|
||||
- `get_cost_for_tokens(input_tokens, output_tokens)` - Calculate text model cost
|
||||
- `get_cost_for_images(num_images)` - Calculate image model cost
|
||||
- `validate_size(size)` - Validate image size for model
|
||||
- `get_display_with_pricing()` - Formatted string for dropdowns
|
||||
|
||||
---
|
||||
|
||||
### Phase 2: Migration & Data Seeding ✅
|
||||
**File:** `backend/igny8_core/modules/billing/migrations/0020_create_ai_model_config.py`
|
||||
|
||||
**Seeded Models:**
|
||||
- **Text Models (5):**
|
||||
- `gpt-4o-mini` (default) - $0.15/$0.60 per 1M | 128K context
|
||||
- `gpt-4o` - $2.50/$10.00 per 1M | 128K context | Vision
|
||||
- `gpt-4.1` - $2.00/$8.00 per 1M | 8K context
|
||||
- `gpt-5.1` - $1.25/$10.00 per 1M | 16K context
|
||||
- `gpt-5.2` - $1.75/$14.00 per 1M | 16K context
|
||||
|
||||
- **Image Models (4):**
|
||||
- `dall-e-3` (default) - $0.040/image | 3 sizes
|
||||
- `dall-e-2` - $0.020/image | 3 sizes
|
||||
- `gpt-image-1` (inactive) - $0.042/image
|
||||
- `gpt-image-1-mini` (inactive) - $0.011/image
|
||||
|
||||
**Total:** 9 models (7 active)
|
||||
|
||||
---
|
||||
|
||||
### Phase 3: Django Admin Interface ✅
|
||||
**File:** `backend/igny8_core/modules/billing/admin.py`
|
||||
|
||||
**Features:**
|
||||
- List display with colored badges (model type, provider)
|
||||
- Formatted pricing display based on type
|
||||
- Active/inactive and default status icons
|
||||
- Filters: model_type, provider, is_active, capabilities
|
||||
- Search: model_name, display_name, description
|
||||
- Collapsible fieldsets organized by category
|
||||
|
||||
**Actions:**
|
||||
- Bulk activate/deactivate models
|
||||
- Set model as default (enforces single default per type)
|
||||
- Export pricing table
|
||||
|
||||
**Access:** Django Admin → Billing → AI Model Configurations
|
||||
|
||||
---
|
||||
|
||||
### Phase 4 & 5: AI Core Integration ✅
|
||||
**File:** `backend/igny8_core/ai/ai_core.py`
|
||||
|
||||
**Updated Functions:**
|
||||
1. `run_ai_request()` (line ~294) - Text model cost calculation
|
||||
2. `generate_image()` (line ~581) - Image model cost calculation
|
||||
3. `calculate_cost()` (line ~822) - Helper method
|
||||
|
||||
**Implementation:**
|
||||
- Lazy imports to avoid circular dependencies
|
||||
- Database-first with fallback to constants
|
||||
- Try/except wrapper for safety
|
||||
- Logging shows source (database vs constants)
|
||||
|
||||
**Example:**
|
||||
```python
|
||||
# Before (hardcoded)
|
||||
rates = MODEL_RATES.get(model, {'input': 2.00, 'output': 8.00})
|
||||
cost = (input_tokens * rates['input'] + output_tokens * rates['output']) / 1_000_000
|
||||
|
||||
# After (database)
|
||||
model_config = AIModelConfig.objects.get(model_name=model, model_type='text', is_active=True)
|
||||
cost = model_config.get_cost_for_tokens(input_tokens, output_tokens)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 6: Validators Update ✅
|
||||
**File:** `backend/igny8_core/ai/validators.py`
|
||||
|
||||
**Updated Functions:**
|
||||
1. `validate_model(model, model_type)` - Checks database for active models
|
||||
2. `validate_image_size(size, model)` - Uses model's `valid_sizes` from database
|
||||
|
||||
**Benefits:**
|
||||
- Dynamic model availability
|
||||
- Better error messages with available model lists
|
||||
- Automatic sync with database state
|
||||
|
||||

|
||||
|
||||

|
||||
## Architecture
|
||||
|
||||
### Two Pricing Models Supported
|
||||
|
||||
**1. Text Models (Token-Based)**
|
||||
- Credits calculated AFTER AI call
|
||||
- Based on actual token usage
|
||||
- Formula: `cost = (input_tokens × input_rate + output_tokens × output_rate) / 1M`
|
||||
|
||||
**2. Image Models (Per-Image)**
|
||||
- Credits calculated BEFORE AI call
|
||||
- Fixed cost per image
|
||||
- Formula: `cost = cost_per_image × num_images`
|
||||
|
||||

## Usage Examples
|
||||
|
||||
### Django Admin
|
||||
1. Navigate to: **Admin → Billing → AI Model Configurations**
|
||||
2. Click on any model to edit pricing
|
||||
3. Use filters to view specific model types
|
||||
4. Use bulk actions to activate/deactivate
|
||||
|
||||
### API Usage (Frontend)
|
||||
```javascript
|
||||
// Fetch all text models
|
||||
const response = await fetch('/api/v1/billing/ai/models/?type=text');
|
||||
const { data: models } = await response.json();
|
||||
|
||||
// Display in dropdown
|
||||
models.forEach(model => {
|
||||
console.log(model.display_name, model.pricing_display);
|
||||
});
|
||||
```
|
||||
|
||||
### Programmatic Usage (Backend)
|
||||
```python
|
||||
from igny8_core.business.billing.models import AIModelConfig
|
||||
|
||||
# Get model
|
||||
model = AIModelConfig.objects.get(model_name='gpt-4o-mini')
|
||||
|
||||
# Calculate cost
|
||||
cost = model.get_cost_for_tokens(1000, 500) # $0.000450
|
||||
|
||||
# Validate size (images)
|
||||
dalle = AIModelConfig.objects.get(model_name='dall-e-3')
|
||||
is_valid = dalle.validate_size('1024x1024') # True
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Next Steps (Optional Enhancements)
|
||||
|
||||
### Short Term
|
||||
- [ ] Add model usage analytics to admin
|
||||
- [ ] Create frontend UI for model selection
|
||||
- [ ] Add model comparison view
|
||||
|
||||
### Long Term
|
||||
- [ ] Add Anthropic models (Claude)
|
||||
- [ ] Add Google models (Gemini)
|
||||
- [ ] Implement A/B testing for models
|
||||
- [ ] Add cost forecasting based on usage patterns
|
||||
|
||||

|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues occur:
|
||||
|
||||
1. **Code Level:** All functions have fallback to constants
|
||||
2. **Database Level:** Migration can be reversed: `python manage.py migrate billing 0019`
|
||||
3. **Data Level:** No existing data affected (CreditUsageLog unchanged)
|
||||
4. **Time Required:** < 5 minutes
|
||||
|
||||
**Risk:** Minimal - System has built-in fallback mechanisms
|
||||

|
||||
|
||||
**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
|
||||
|
||||

|
||||
|
||||
## 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
|
||||
```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)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Profit Margins
|
||||
|
||||
| Model | OpenAI Cost (1500 in + 500 out) | Credits | Revenue | Profit |
|
||||
|-------|----------------------------------|---------|---------|--------|
|
||||
| gpt-4o-mini | $0.000525 | 20 | $0.2000 | 99.7% |
|
||||
| gpt-4o | $0.008750 | 20 | $0.2000 | 95.6% |
|
||||
| gpt-4.1 | $0.007000 | 20 | $0.2000 | 96.5% |
|
||||
| gpt-5.1 | $0.006875 | 20 | $0.2000 | 96.6% |
|
||||
| gpt-5.2 | $0.009625 | 20 | $0.2000 | 95.2% |
