Bug Description
I was on a session with Opus 4.8 and did not exit the session - we can call this session A. In another session (B), I had updated and was running Opus 5 and Fable 5. However, in the session A where I had not exited and come back in, it was consuming my tokens as Fable 5 as I could see it go up in the useage stats in the app.

It was consuming them very quickly, even though I was on Opus 4.8. From that perspective, it used a lot of my tokens, and I was not aware until the last minute.
