Update on the new reasoning popover in ChatGPT web app prompt composer - there's now even a keyboard shortcut to cycle through reasoning levels, and it looks like these levels correspond to "Quick" (low) = GPT-4o, "Think a little" (medium) = o3-mini, and "Think harder" (high) = o3-mini-high

Well, my version better isn’t?

Preparation for GPT 5

this isn't out yet, right?

Nope

Is it so you don't have to constantly switch between models? Preparing for GPT 5, I guess.

to be clear when you say "o3-mini" without a specific identifier its medium compute right?

Yes, exactly - the o3-mini in ChatGPT is using a medium level of reasoning effort

Any thoughts on whether this is an improvement? I feel like making you choose isn't going to work for most users.

In the sense of "don't make me think", it's probably only an intermediate/advanced setting to override or change the auto-selected reasoning level
