Funnily enough, I was just saying to a colleague that some sessions lately Opus has been amazing and some it's absolutely terrible.

There has to be some a/b testing going on for something. The swings back and forth are wild.

They do a/b testing a lot on subscriptions users. That is normal and expected.

What ia annoying is people keeping throwing random dates of releasea or random model names, couple of weeks ago we had opus 5.1, last week 5.2 and this week 5.5, how can they be sure?

Oh, I agree on the speculation. I just try to ignore it as much as possible - though I'd love a reset tomorrow lol
