Problem
Now, 6.1 on extra high makes more mistakes than 5.6 at high. It was a lot better a few days ago ..........

What changed to make it faster? From my experience, 6.1 now performs at roughly the level of Luna. My subscription runs until 7 October, and I've had to switch back to Sol 5.6 because 6.1's output quality dropped noticeably.

Codex extension for vs code doesn’t even work anymore, so it would be nice to get a rollback to one that does with 6.1 Sol support. The last working version was prior to the rollout. Additionally, on ChatGPT web/app, the usage page is busted and shows 3-15 empty tables.
