# Get public model data

> List ranked public model records or return one exact model.

Use `model_id` by itself for an exact lookup. For lists, use `sort`, `order`, `limit`, and `offset`.

<Warning>
  Keep unavailable values as unknown. Demand does not prove that a model is underserved. The separate supply feed is outside the formal v1 models schema.
</Warning>

See the [query guide](/api-reference#query-reference) and [field glossary](/api-reference/fields).

            no public weights. weights_access_unknown: No exact public
            checkpoint link exists. No checked source says that the weights are
            closed. open_checkpoint_unavailable: An exact checkpoint claim
            exists. The collector cannot collect the repository.
            size_calculation_failed: The collector collected the checkpoint. The
            checked facts do not support one size. Legacy public BF16 reasons
