## 📊 Data Flow

### 1. User Interaction
```
User Types → Gradio UI → Chat Route → Model Handler
                                    ↓
                             Phi-3 Generates Response
                                    ↓
                             Dataset Manager Saves
                                    ↓
                          Response + Interaction ID
```

### 2. Feedback Collection
```
User Rates (1-5) → Feedback Route → Dataset Manager
                                    ↓
                              feedback.jsonl
```

### 3. Training Cycle
```
Admin Triggers → Retrain Route → Retrain Pipeline
                                    ↓
                      Load Quality Data (score ≥3)
                                    ↓
                         Fine-tune with LoRA
                                    ↓
                      Save New Model Version
                                    ↓
                    Reload Model Handler
```

## 🎓 Training Process Details

### Step-by-Step
1. **Data Collection** (Continuous)
   - Users chat with AI
   - Interactions saved to `vish_dataset.jsonl`
   - Each entry: prompt, response, category, timestamp

2. **Quality Feedback** (User-driven)
   - Users rate responses 1-5 stars
   - Feedback saved to `feedback.jsonl`
   - Low-quality data (< 3 stars) excluded from training

3. **Training Trigger** (Admin or Scheduled)
   - Admin clicks "Start Training" in UI
   - Or API call: `POST /api/admin/retrain`
   - Requires minimum samples (default: 10)

4. **Data Preparation** (Automatic)
   - Filter interactions with score ≥ 3
   - Deduplicate based on content hash
   - Format as instruction-response pairs
   - Apply Phi-3 chat template

5. **LoRA Fine-Tuning** (10-30 min on CPU)
   - Load base Phi-3 model
   - Apply LoRA adapters (rank=16, alpha=32)
   - Train for 3 epochs (configurable)
   - Small batch size (2) for free-tier

6. **Model Versioning** (Automatic)
   - Save LoRA adapters to `models/vish-ai-mini/latest/`
   - Update metadata.json with version & metrics
   - Version format: `v20241016_143022`

7. **Deployment** (Automatic)
   - Model handler reloads
   - New version used for all responses
   - Old base model still available

### Configuration
```python
# In app/retrain.py
min_samples = 10          # Minimum interactions needed
epochs = 3                # Training iterations
batch_size = 2            # Small for free-tier
learning_rate = 2e-4      # LoRA learning rate
lora_r = 16               # LoRA rank (lower = less memory)
lora_alpha = 32           # LoRA scaling factor
```
