  title: Hyperbolic Research Summarize And Narrate
  summary: Confirm a reasoning model, summarize a topic with it, and narrate the summary.
  description: >-
    A three-stage briefing pipeline. The workflow lists the live model catalog
    to confirm a reasoning or instruct model is available, asks that model for a
    short spoken-style summary of a topic, then converts the summary into speech
    audio with the text-to-speech endpoint. Each step inlines its request and
    inline Authorization Bearer credential so the flow reads and runs without
    opening the OpenAPI sources.
