After successfully authenticating using the IBM watsonx.ai Authenticator node, you can select an embedding model. Refer to IBM watsonx.ai documentation for more information on available embedding models. At the moment, only the embedding models from foundation models are supported.
Note : If you want to use a space, make sure that the space has a valid runtime service instance. You can check this at IBM watsonx.ai Studio under Manage tab in your space.
