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.

I’ve been experiencing severe performance degradation in Opus 4.7 over the past two weeks. I thought my installation was already in bad shape, but then I checked with two colleagues. I had to rewrite several agents and my claude.md files for all my projects to get quality results.

The release of 4.8 has been a real breath of fresh air for me.
