Recent change
Rolling 7-day score: −7.1 points vs 7 days ago. Discussion mix can affect scores; this does not establish a cause.
Source coverage and discussion concentration
Hacker News 5 · Reddit 58 · RedNote 1 · Zhihu 5
49 identifiable discussions cover 64/69 comments; the largest has 5. Remaining thread identities are unknown; this is not a count of independent users.
Selected individual opinions
One user fed both models a script meant to print the max of two numbers; Opus 5 deduced it correctly, while Opus 5.5 wrongly concluded it prints 1/0. One user replied that even after the nerf, Opus 5.5 is still much better than Opus 5.

A macos photo editor. Swift and Rust. Mostly an experiment to see how large of a project I could make without looking at any code, and how to approach scale issues.

Opus 5.5 nerfing - how to measure, how to spot, how to sue
Interested to hear how others are getting on with post-nerf Opus 5.5.
Comment context
For example if you have Opus 5 process a bunch of reviews from an subagent fanout that is reviewing code, then synthesizing those into a final report. It keeps more of the actual defects vs 5.5, by a small margin. But it also keeps more false positive and takes about twice as long and twice as many tokens as 5.5
Comment context
But right around the time my monthly limit reset this evening, I noticed an extreme shift in communication style and coding behavior that feels suspiciously like Opus 5 (O5). For the last week, O5.5 would take my requirements and immediately get to work, usually knocking out a feature in minutes and doing an incredible job across implementation, UX, architecture, and token efficiency. Tonight, I’m seeing something very different. The first tell was the communication style. O5.5 suddenly started responding to feature requests with these glazing pre-implementation narratives and generic estimates like, “That’s a great idea. That’s two days’ worth of work and it will be amazing,” and then proceeding to implement the feature in the most slopcode-slathered way possible. That was a very specific and particularly annoying characteristic of O5, so I clocked it immediately. The next tell: a sudden reversion to walls-of-text responses when prodded for details on...*anything*.
Comment context
I feed it a script which takes two numbers and prints the max of the two numbers. Opus 5.5 thinks it prints 1/0 instead of the max numbers.

opus5太慢了
Comment context
Actually I thought Opus 5 was great, and don't feel like 5.5 is some incredible leap forward from it
Comment context
Tried to use muse for PR review and opus 5 was hating on the feedback and instead opus found a different real issue that muse didn't.
