Structured Output

Structured output refers to AI model responses that follow a specific, machine-readable format such as JSON, XML, CSV, or a defined schema. Unlike free-form text responses, structured outputs can be reliably parsed by code, validated against schemas, and integrated directly into applications and workflows without manual extraction.

Example

Instead of asking the AI "What's the sentiment of these reviews?" and getting a paragraph response, you request structured output: "Respond with a JSON array where each object has 'review_text', 'sentiment' (positive/negative/neutral), and 'confidence' (0-1)." The result is directly usable in your application.
