  title: OpenAI Batch Job
  summary: Upload a batch input file, create a batch, poll until complete, and read the output file id.
  description: >-
    Uploads a JSONL batch input file with the batch purpose, creates a batch
    against a target endpoint, polls the batch until it reaches a terminal
    status, and on completion returns the output file id holding the results.
    Every step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
