# 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
---
### Phase 7: REST API Endpoint ✅
**Endpoint:** `GET /api/v1/billing/ai/models/`
**Files Created/Updated:**
- Serializer: `backend/igny8_core/modules/billing/serializers.py`
- ViewSet: `backend/igny8_core/modules/billing/views.py`
- URLs: `backend/igny8_core/business/billing/urls.py`

GET /api/v1/billing/ai/models/?default=true
```
**Get Single Model:**
```bash

---
## 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`
### Data Flow
```
User Request
AICore checks AIModelConfig database
If found: Use database pricing
If not found: Fallback to constants
Calculate cost
Deduct credits
Log to CreditUsageLog
```
---
## Files Modified

6. `modules/billing/views.py` - Added AIModelConfigViewSet (75 lines)
7. `business/billing/urls.py` - Registered API endpoint (1 line)
**Total:** ~750 lines of code added/modified
---
## 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

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)

---
## 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% |
---
