I thought this was going to talk about a nerfed Opus 4.6 experience. I believe I experienced one of those yesterday. I usually have multiple active claude code sessions, using Opus 4.6, running. The other sessions were great, but one session really felt off. It just felt much more dumbed down than what I was used to. I accidentally gave that session a "good" feedback, which my inner conspiracy theorist immediately jumps to a conclusion that I just helped validate a hamstrung model in some A/B test.
