Overview: Structured Output Pipeline

Grammar-constrained generation guarantees schema compliance but adds ~15–30% latency. Instructor + Pydantic is the production standard: fast path uses JSON mode (95% reliable), Pydantic catches the remaining schema violations, and a retry loop with error feedback resolves the last 5%. This layered approach gives both speed and reliability.
