Prompting
Structured Output
Model output constrained to a schema or format.
Plain-English explanation
Structured output is useful for APIs, extraction, automations, and evals. JSON schema, Pydantic, and validation layers make outputs more reliable.
Why it matters
Structured Output matters because it affects how AI systems are designed, evaluated, priced, or trusted. Knowing the term helps you ask better questions and avoid vague implementation decisions.
- Ask how it changes quality, cost, speed, or safety.
- Look for concrete examples in the workflow you are building.
- Document the tradeoff before choosing a tool or architecture.
