Structured Output

Structured output constrains a model's response to a defined schema — JSON, an enum, a typed object — instead of free-form prose, so the calling code can parse it reliably without brittle regex or string matching. It's foundational to tool calling and agent loops, where a wrongly-shaped response breaks the next step in the chain. Enforcing and validating the schema, not just asking nicely for JSON, is what makes it dependable in production.
