Models and the effort slider

Pro runs Claude Sonnet 5 and GPT-5.6 Luna; Edge adds Grok 4.5 with live X search. A conversation is pinned to the model it started on. The picker sets the default for your next new session, not the current thread.

The effort slider (Low to Max) trades depth for allowance. Higher effort reasons harder and uses more of your budget, so save Max for the questions that deserve it.
