For the notebook at https://github.com/elastic/elasticsearch-labs/blob/main/notebooks/integrations/cohere/inference-cohere.ipynb. In the following code:

API_KEY = getpass("Enter Cohere API key:  ")

client.inference.put_model(
    task_type="text_embedding",
    model_id="cohere_embeddings",
    body={
        "service": "cohere",
        "service_settings": {
            "api_key": API_KEY,
            "model_id": "embed-english-v3.0",
            "embedding_type": "int8",
        },
        "task_settings": {},
    },
)

Cohere does not work for Elastic Stack normal release. It returns the following error:

BadRequestError: BadRequestError(400, 'status_exception', 'Unknown service [cohere]')

For Elastic Stack 8.12 installation.

According to our documentation at https://www.elastic.co/guide/en/elasticsearch/reference/current/put-inference-api.html. Currently, only the following services are supported:

ELSER
OpenAI
Hugging Face

According to the reply from our Slack discussion, "Cohere" is only currently supported on Serverless.

It would be good to point out this to the developers.
