/ quick answer
Structured generation (Outlines, Instructor, Gemini controlled generation) uses grammar constraints during decoding so the output is guaranteed valid — no parse-retry loop. Constraining decoding to match a schema at every token.
Constraining decoding to match a schema at every token. Structured generation (Outlines, Instructor, Gemini controlled generation) uses grammar constraints during decoding so the output is guaranteed valid — no parse-retry loop. In practice: A Zod schema is compiled to a JSON grammar and enforced token-by-token.
