Write the Structured Outputs Request Shape
Explore how to create a structured outputs request shape that instructs AI models to generate validated JSON matching a defined schema. Learn to ensure the UI only renders fully validated data by waiting for complete streaming output, applying strict schema rules, and maintaining stable request wiring. This lesson guides you through setting up reliable AI responses for predictable UI rendering and early failure detection.
We'll cover the following...
Choosing structured output over plain text is a UI-risk decision. Actually getting that structure back from the model is a request-shape decision, and it has its own way of going wrong.
With the choice between plain text and structured JSON now tied to concrete UI risks like parsing, unsafe rendering, and unreliable actions, the next step is writing a request that actually produces that structure. A Structured Outputs request succeeds or fails based on request shape, not prompt wording, so it helps to start from a complete reference snippet you can keep next to the UI code that consumes it. The UI contract here is simple and strict. After streaming completes, the frontend parses one JSON object, validates it against a known schema, then renders the ...
