  title: ChatGPT Structured JSON Output Response
  summary: Generate a response constrained to a caller-supplied JSON schema.
  description: >-
    Uses the Responses API text.format configuration to force the model to
    return JSON that conforms to a caller-supplied schema. The response is
    created with strict json_schema formatting, then retrieved to extract the
    structured output text once generation settles. The flow branches when the
    response does not complete so callers can react to incomplete output. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
