I do not understand. Could you please elaborate?

If you use stateful API, there is a checkbox for restful calls, then, ID of the last message is passed to Grok, so Grok knows your previous queries and the context.

Also, you can configure file to store chat history. You can have one global file for all projects or a separate chat history file for each project. On the left of the grok model selection drop down you have icon to access project level settings. It allows you to specify file to store grok chat for the project.

I am interested in having multiple chat history files per project and being able to swap between them in the UI.

Ah, multiple chat history files per project. In theory this is possible even now. You can change the grok chat history file per project any time. But I understand you would like to have some kind of an easy UI to do it. Like, having a list of files and switch between them with a few clicks?

Yes, exactly. That would be very helpful.
