We recently upgraded from 8.14.3 to 8.17.2 to make full use of the \*\*AI Assistant, but we're running into an issue again. 😩

When trying to add items to the knowledge base via the Knowledge Base settings page, we get the following error:

```auto
Error: exception
	Caused by:
		resource_not_found_exception: Could not find trained model [obs_ai_assistant_kb_inference]

```

I’m not sure if **`obs_ai_assistant_kb_inference`** should be listed under trained models, but it is not there

Should this model have been installed automatically as part of the upgrade?

Is there a way to manually deploy or re-register the missing model?

Has anyone else encountered this after upgrading?

Any insights or fixes would be greatly appreciated! Thanks in advance.

Has anyone experienced the same or is this more or less friction less for others?

I updated to 8.17.3, and also have the same issue. ☹

The issue on our side was probably caused by not having enough resources for another model depoyment. Not that any of the error messages pointed in that direction 🙈

After adding another ML node, a model with instance ID "obs\_ai\_assistant\_kb\_inference" was made available and we are able to add stuff to the KB.
