The CDCK-hosted LLMs are available experimentally for any hosted sites that opt in via the toggle under the “What’s New” feed. During this phase, there is no extra cost and no usage limit other than fair use.
As for CDCK-hosted embeddings models, these have been live for our hosted customers for over a year now, but only recently became visible in the UI with the newly created “Embeddings” tab under AI configuration. This is not experimental and is offered as part of our hosting service.
