Returns active models that can be used with the Batch API. Use this endpoint before creating a batch when you need to discover provider-specific batch constraints such as:
  • allowed endpoint values for batch input rows
  • supported completion_window values
  • model/provider-specific parameters exposed through supported_params_detail and supported_parameters_detail
The response is a standard list envelope. Each item includes:
  • model
  • name
  • status
  • input_types and output_types
  • supported_params
  • supported_parameters
  • supported_params_detail
  • supported_parameters_detail
  • providers, each with provider-level supported parameter detail
  • pricing
supported_parameters is the OpenRouter-compatible alias for supported_params. supported_params_detail and supported_parameters_detail are aliases for the same structured metadata. New clients should prefer supported_parameters and supported_parameters_detail; existing clients can continue reading supported_params and supported_params_detail. You can filter models by supported batch parameter with the params query parameter. Repeat it or pass a comma-separated list. The filter accepts canonical names and aliases from supported_parameters_detail, so params=request_endpoint can match models whose canonical parameter is endpoint, and params=window can match completion_window.
