Structured Outputs (Moved)

Structured output returns a typed object from the model. Pick the page for the shape you need:

• Overview: what structured output is, which schema libraries work, provider support, and which page to read.
• One-Shot Extraction: one prompt in, one typed object out. Use it when you do not need streaming or chat history.
• Streaming UIs: useChat({ outputSchema }) fills a UI field by field with partial and final.
• Multi-Turn Chat: each completed run adds a typed response to the message history. The data of its structured-output part has the type of your schema.
• With Tools: use outputSchema with the agent loop, including server-tool approvals and client tools.
