To register a remote model to the model group created in step 1, provide the model group ID from step 1 in the following request.
Because pretrained **sentence transformer** models originate from the ML Commons model repository, you only need to provide the `name`, `version`, `model_group_id`, and `model_format` in the upload API request:

You can find the `url` and `model_content_hash_value` in the model config link for each model. For more information, see the [Supported pretrained models section](#supported-pretrained-models). Set the `function_name` to `SPARSE_ENCODING` or `SPARSE_TOKENIZE`.
Note that the `function_name` parameter in the request corresponds to the `model_task_type` parameter in the model config. When using a pretrained model, make sure to change the name of the parameter from `model_task_type` to `function_name` in the model upload request.
