Models and the effort slider

Pro and Edge both offer Claude Fable 5.1, Sonnet 5 and Opus 5; GPT-5.6 Sol, Terra and Luna; GPT-6 Astra; and Grok 4.7 with live X search. A conversation stays pinned to its selected model. Choosing from the picker updates the current conversation and becomes the default for the next new session.

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.
