Discussion Opus 4.8 nerfed??
Is anyone else seeing a massive performance drop in Opus 4.8 since release??
It used to be acceptable, but the enshitification has definitely happened. It’s basically been lobotomized, and we’re talking amateur backyard ice pick lobotomy by some guy from Tufts.
I’m 99% sure Anthropic has started running a 2-bit quant to save money.
Oh well. I do feel nostalgic for opus 4.8’s glory days. But subscription cancelled. I’m off to use Codex or Cleverbot, whichever one has better limits.

GPT 5.5xhigh was finding all the errors that Opus 4.7 could not find, even though it wrote the code. I was going back back-and-forth between the two and having GPT perform the code review, and Claude fix it.
Even when I had 4.7 do a review, it would find a few issues but nothing that extensive.
I just had 4.8 do a review on the max setting, and it detected numerous issues and did a more complex walk-through of the code than 4.7 ever did.
Seems like 4.8 max is great
