Structured Outputs

Overview

Who is this for? Developers building applications that need AI-generated content in predictable, structured formats like JSON, XML, or custom schemas for databases, APIs, and data processing pipelines.

What you'll achieve: Generate consistently formatted data with guaranteed schema compliance, enabling seamless integration with existing systems and automated data processing workflows.

Structured outputs ensure AI responses conform to predefined schemas, making them ideal for data extraction, form filling, API responses, and database operations.
