Structured Output

The capability of AI models to generate responses in a specific, machine-parseable format—JSON, XML, typed objects—rather than free-form text. Structured output is essential for AI agents because their outputs often feed directly into other systems: a sales agent must output a JSON object that the CRM API accepts, a finance agent must produce structured transaction categories, and a coding agent must generate valid code in the correct language. Most major LLM providers now support constrained output schemas that guarantee valid structured responses.
