## 🚀 Launch Plan

### Phase 1: Critical Fixes (Do First)
1. Update Module 14 transformer for KV caching
2. Move quantization content to correct module
3. Clear out incorrect content from modules

### Phase 2: Parallel Development (5 Agents)
Launch 5 parallel agents to develop:
- Agent 1: Module 15 (Acceleration) - Polish existing
- Agent 2: Module 16 (Quantization) - Major development
- Agent 3: Module 17 (Compression) - New implementation
- Agent 4: Module 18 (Caching) - New implementation
- Agent 5: Module 19 (Profiling) - Complete rewrite

### Phase 3: Final Module (After Phase 2)
- Module 20 (Benchmarking) - Requires Module 19 completion

### Phase 4: Integration Testing
- Test all optimizations together
- Verify cumulative speedups
- Ensure no conflicts between optimizations
