## Known Limitations

1. **API Dependency**
   - Pages require backend APIs to be running
   - Fallback data is minimal
   - Some features require HuggingFace models to be loaded

2. **Chart Rendering**
   - Requires Chart.js library to be loaded
   - May fail if OHLCV data is unavailable
   - Gracefully degrades to error state

3. **Model Loading**
   - Models must be initialized on backend
   - Some models require authentication
   - Loading can take time on first request

## Future Improvements

1. **AI Analyst**
   - Add more technical indicators
   - Implement real-time updates via WebSocket
   - Add historical analysis comparison
   - Implement custom timeframe selection

2. **Models Page**
   - Add model performance metrics
   - Implement model comparison feature
   - Add model training history
   - Implement batch testing

3. **General**
   - Add caching for API responses
   - Implement progressive loading
   - Add export functionality
   - Improve mobile responsiveness

## Deployment Notes

1. **No Backend Changes Required**
   - All fixes are frontend-only
   - Existing API endpoints are used
   - No database migrations needed

2. **Browser Compatibility**
   - Modern browsers (Chrome, Firefox, Safari, Edge)
   - Requires ES6+ support
   - CSS Grid and Flexbox support required

3. **Dependencies**
   - Chart.js 4.4.1 (loaded from CDN)
   - No additional npm packages required

## Summary

All issues with the AI Analyst and Models pages have been resolved:

✅ **Data Display**: Both pages now properly fetch and display data from backend APIs
✅ **Styling**: Enhanced with modern glassmorphism effects and proper layouts
✅ **Error Handling**: Graceful fallbacks and clear error messages
