Phase 7 of 9
Advanced Techniques
Days 61-70 (10 days)
Production-Grade Skills
Time to level up. This phase covers fine-tuning, local LLMs with Ollama, monitoring, caching, security, and voice interfaces - everything you need for production AI applications.
You'll build a fully private local assistant that works without any internet connection.
What Problems Will You Solve?
Fine-tuning
Prompting can't match your exact company style/format
Local LLMs
$500/month API bills, can't send data to cloud
Monitoring
Something's wrong but no idea which prompt failed
Caching
Same question 100 times = 100 API calls = $$$
Security
One user automated 10,000 requests - API key banned
