## 🔧 Configuration

### Enable Deep Think Mode

```typescript
// frontend/src/constants.ts

export const CONFIG = {
  // Use Gemini 3 Pro for all analysis
  DEFAULT_MODEL: 'gemini-3-pro-preview',
  
  // Enable extended reasoning
  DEFAULT_THINKING_LEVEL: 'high',
  
  // Show AI's thought process
  ENABLE_THOUGHT_TRANSPARENCY: true,
  
  // High-quality image analysis
  MEDIA_RESOLUTION: 'high'
};
```

### Cost Optimization Mode

```typescript
export const CONFIG = {
  // Use faster, cheaper Gemini 3 Flash
  DEFAULT_MODEL: 'gemini-3-flash-preview',
  
  // Quick analysis
  DEFAULT_THINKING_LEVEL: 'low',
  
  // Standard quality
  MEDIA_RESOLUTION: 'medium'
};
```

---

## 🐳 Docker Alternative

Prefer containers? One command deployment:

```bash
# Build and run
docker-compose up -d

# Check status
docker-compose ps

# View logs
docker-compose logs -f
```

Access at http://localhost:3000

## 🆘 Troubleshooting

### Issue: "Gemini API Key Invalid"

**Solution**:
```bash
# Verify key is set
cat .env | grep GEMINI_API_KEY

# Ensure no extra quotes or spaces
GEMINI_API_KEY=AIzaSy...  # Correct
GEMINI_API_KEY="AIzaSy..." # Wrong (remove quotes)
```

### Issue: Camera Not Working

**Solution**:
1. Check browser permissions: `chrome://settings/content/camera`
2. Use HTTPS (camera requires secure context)
3. Try different browser (Chrome/Edge recommended)

### Issue: "Model Not Found"

**Solution**:
```bash
# Ensure using Gemini 3 models
# Check frontend/src/services/geminiService.ts

const MODEL_NAME = 'gemini-3-flash-preview';  // Correct
// NOT 'gemini-2.0-flash-exp' (old model)
```

### Issue: Console Shows Errors

**Solution**:
```bash
# Clear cache and reinstall
rm -rf node_modules package-lock.json
npm install
npm run dev
```

## 💡 Pro Tips

### Optimize for Speed
```typescript
// Use Flash model with low thinking
model: 'gemini-3-flash-preview',
thinkingLevel: 'low',
mediaResolution: 'medium'
// → 3x faster, 6x cheaper
```

### Optimize for Accuracy
```typescript
// Use Pro model with deep think
model: 'gemini-3-pro-preview',
thinkingLevel: 'high',
mediaResolution: 'high'
// → 30% more accurate, better reasoning
```

### Adaptive Configuration
```typescript
// Let AegisAI automatically choose
// based on threat level and scene complexity
ENABLE_ADAPTIVE_MODEL_SELECTION: true
// → Best balance of speed, cost, and accuracy
```
