## Next Steps (Immediate Priorities)

### Priority 1: Enhanced Model Testing & Validation 🎯
**Current Status**: Enhanced model deployed and running in Gradio app
**Immediate Actions**:
1. **Comprehensive Testing**: Test enhanced model across diverse topics
   - Validate improved cynical tone and doom-laden openings
   - Test non-telecom topics (dating, work, social media, health)
   - Compare outputs with original model for style improvements

2. **Style Accuracy Assessment**: Evaluate if 90%+ style target achieved
   - Test signature phrases ("What could possibly go wrong?")
   - Validate dark analogies and visceral metaphors
   - Assess British cynicism and parenthetical snark

3. **Performance Validation**: Ensure enhanced model maintains performance
   - Verify 2-5 second generation times on Apple Silicon
   - Monitor memory usage and stability
   - Test various generation parameters

### Priority 2: User Experience Refinement
**Current State**: Enhanced Gradio app functional with improved model
**Planned Improvements**:
- Add non-telecom example topics to showcase versatility
- Improve UI styling and user feedback
- Add model comparison features (original vs enhanced)
- Better parameter controls for generation settings

### Priority 3: Documentation & Deployment
**Current State**: Enhanced model working, documentation needs updating
**Required Updates**:
- Update README with enhanced model capabilities
- Document new system prompt structure and style elements
- Create user guide for enhanced features
- Prepare deployment documentation

## Active Decisions and Considerations

### Model Architecture Decisions
- **Staying with Zephyr-7B-Beta**: Proven to work well, no need to change base model
- **LoRA Approach**: Confirmed as optimal for hardware constraints and training efficiency
- **Apple Silicon Focus**: Continue optimizing for M1/M2/M3 as primary target platform

### Training Strategy Decisions
- **Conservative Approach**: Prefer stable training over aggressive optimization
- **Quality over Quantity**: Focus on high-quality training examples rather than volume
- **Iterative Improvement**: Small, measurable improvements rather than major overhauls

### Development Workflow Decisions
- **Memory Bank Documentation**: Maintain comprehensive documentation for context continuity
- **Modular Architecture**: Keep components separate for easier testing and improvement
- **Validation-First**: Always validate changes with test scripts before deployment

## Important Patterns and Preferences

### Code Organization Patterns
- **Separation of Concerns**: Keep data processing, training, and inference separate
- **Configuration Centralization**: All training parameters in one place
- **Error Handling**: Comprehensive logging and graceful degradation
- **Hardware Abstraction**: Automatic device detection with fallbacks

### Development Preferences
- **Apple Silicon Optimization**: Primary development and testing platform
- **Memory Efficiency**: Always consider RAM usage in design decisions
- **User Experience**: Prioritize simplicity and responsiveness
- **Documentation**: Maintain clear, comprehensive documentation

### Quality Standards
- **Technical Accuracy**: Generated content must be factually correct
- **Style Consistency**: Aim for recognizable Iain Morris voice
- **Performance**: Sub-5-second generation times
- **Reliability**: Stable operation without crashes or memory issues
