Unclear description for Gemini 2.5 Flash

Gemini 2.5 Flash is hybrid, so it support turning thinking on and off. It's not clear if Assistant uses it with thinking enabled or disabled.

You should mention that somewhere in the UI, and ideally provide an option to toggle thinking on and off for this model.

Right, sorry I'm just getting back to this -- right now if it's not marked as thinking then it would be the non-thinking variant.

The UI is getting updated with more options to give control over that soon (also reasoning effort, etc.)
