# List built-in model provider families

`GET /v1/model_providers`

Retrieve the built-in model provider families available to this deployment. Built-in families are a fixed enum rather than stored records, so this list is not paginated; it is narrowed by the PHOENIX_ALLOWED_PROVIDERS environment variable when that is set. User-defined providers are listed separately by `GET /v1/custom_model_providers`.
