Schema Output & Code
AI Structured Outputs Guide
AI models perform best when returning structured JSON matching a predefined schema. System prompts use descriptions within the schema as semantic instructions for value extraction.
OpenAI Strict mode requires additionalProperties: false at all levels and all fields must be marked as required. Gemini uses responseSchema in generation config. Pydantic and TypeScript provide compile-time safety for your application code.
