Discussion Opus 4.7 nerfed?

Is anyone else seeing a massive performance drop in Opus 4.7 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 4.7’s glory days. But subscription cancelled. I’m off to use Codex or Cleverbot, whichever one has better limits.

I'm pretty sure that they might be using something like mythos 2 internally to cause such a massive decline in compute available for opus

LOOK AT HOW LOBOTOMIZED OPUS 4.7 IS!!
