  title: Hugging Face Search and Inspect a Model
  summary: Search the Hub for a model, fetch its full record, then inspect a specific revision.
  description: >-
    A discovery flow over the Hugging Face Hub API. The workflow runs a
    full-text model search, selects the top match, retrieves the detailed model
    record by its repository id, and then reads the model information pinned to a
    specific Git revision (branch, tag, or commit SHA). Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Find a model by search term and inspect it at a chosen revision.
  description: >-
    Searches the Hub for models matching a query, takes the first result, loads
    the full model card, and resolves the model state at a specific revision.

    - search
    - revision
