Model Changer is Buggy (e.g. reverting while typing query, gets stuck after lots of changes)

I use gpt-4o-mini primarily cause it's fast and unlimited on pro, but pull out the big guns (sonnet or opus) pretty regularly too, and in the latest release (v0.41.3, commit: 51c8aff7cb5a89f4a0e462fbacab938bdbfaf140) something has changed that causes the model to keep switching on it's own.

It primarily happens in the Chat pane (cmd+L) but sometimes happens in the composer and cmd+k views too.

Generally the flow is something like:

• I open the chat panel and the model selector is set to gpt-4o-mini
• I decide I want to use Sonnet for this question and change the model
• I start typing my query, and at some point while I'm typing the mode switches back to gpt-4o-mini on it's own without me having clicked the model selector dropdown, and when I hit Enter I inadvertently send my query to 4o-mini instead of sonnet.

It's some sort of delayed reaction thing, it's not always gpt-4o-mini -> claude-3.5-sonnet, I've seen it happen quite a few times in the other direction as well. It's can be annoying cause it often leads to me eating up my premium sonnet requests on trivial issues that I had been trying to use gpt-4o-mini for.

I've even on occasion seen it switch on it's own while in the middle of generating an answer (which is weird to watch -- it types out half an answer and then essentially switches models and re-generates the answer using the model it switched back to instead of the one I picked).

Any idea what the cause is or how to fix or workaround it it?

Hi, I can kind of recreate this.

If I go to type a query, and then change the model a lot at random, at some point it gets stuck and won't change again. I'll flag to the devs!

Oh interesting! It hadn't occurred to me as relevant until I saw your message, but I have a habit of hitting cmd+/ repeatedly (like 6 times in a row) to make the model picker loop around without having to touch the mouse. Might be a delayed reaction from so many model switches in a row that causes the issue
