Model change in any case

[bussard76]

Situation:
Because of budget restrictions a model ran out of tokens.

Problem:
I can not "maintain" a rooms knowledge nor can I change the model/provider, since the later is only possible after the rooms knowledge is maintained.

To help me out I changed the model/provider setting in the current thread.json

I should at least change the provider and keep the model (changing from github copilot subscription to openAI with the same model)...
