  title: ChatGPT Create and Poll a Response
  summary: Create a stored response and poll it until generation completes.
  description: >-
    Submits a prompt to the OpenAI Responses API and then polls the stored
    response by id until its status leaves the in_progress state. The flow
    branches on the terminal status so a completed response surfaces its
    generated text while a failed or incomplete response surfaces the error
    or the reason the model stopped early. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.

  summary: Create a Responses API response and poll until it reaches a terminal status.
  description: >-
    Creates a stored response from a text prompt, then retrieves it by id and
    loops while the status is in_progress. Once the response settles it routes
    to a completed, failed, or incomplete terminal step.
