Structured output
Forcing the model to reply in a **machine-readable shape** — JSON, XML, or a fixed schema — instead of free-form prose.
When to use
APIs, form filling, extracting fields from text, feeding results into databases or downstream code.
When not to
Creative writing or open-ended chat where rigid schemas fight the task.
Example
{
"sentiment": "positive",
"topics": ["shipping", "refund"],
"urgency": 3
}
