What happened: Do evals the Airbnb way

Airbnb published a three-layer evaluation framework for generative AI: programmatic checks, LLM judges, and human review. Pydantic demonstrated implementing it end-to-end.

Why it matters: Do evals the Airbnb way

Engineers building production AI systems need evaluation strategies that scale beyond manual testing and catch real failure modes before deployment.

Watch out: Do evals the Airbnb way

The framework requires reading 50 to 100 actual outputs first to identify real failures. Generic evaluators written without seeing failures mostly measure the author's assumptions, not system quality.
