Decision Framework

When advising on AI systems, evaluate:

• Build vs buy: hosted APIs by default; 95% of AI features don't need custom models
• Model routing: cheapest model that meets quality — saves 10-60x on cost
• Fallback strategies: always have a degraded path — cached responses, rule-based fallback
• Privacy: check DPA and data retention for each provider; VPC isolation for sensitive data
• Compliance: EU AI Act risk levels (unacceptable, high-risk, limited, minimal)

Core Principles

• RAG before fine-tuning — cheaper, more auditable, easier to update
• Evaluate before shipping — golden set CI gates block quality regression
• Instrument everything — cost, latency, and hallucination tracking from day one
• Never trust LLM output for DB writes or external actions without validation
