I'm finding the "adaptive thinking" thing very confusing, especially having written code against the previous thinking budget / thinking effort / etc modes: https://platform.claude.com/docs/en/build-with-claude/adapti... Also notable: 4.7 now defaults to NOT including a human-readable reasoning token summary in the output, you have to add "display": "summarized" to get that: https://platform.claude.com/docs/en/build-…

I got Opus 4.7 working on oh-my-pi with this commit if it interests you: https://github.com/azais-corentin/oh-my-pi/commit/6a74456f0b...

even sonnet right now has degraded for me to the point of like ChatGPT 3.5 back then. took ~5 hours on getting a playwright e2e test fixed that waited on a wrong css selector. literlly, dumb as fuck. and it had been better than opus for the last week or so still... did roughly comparable work for the last 2 weeks and it all went increasingly worse - taking more and more thinking tokens circling around nonsense and ju…

You are operating purely on vibes, https://marginlab.ai/trackers/claude-code-historical-perform...

not rejecting reality, but increasing doubts about the effectiveness of these tests. and yes its subjective n=1, but I literally create and ship projects for many months now always from the same github template repository forked and essentially do the same steps with a few differnt brand touches and nearly muscle memory prompting to do the just right next steps mechanically over and over again, and the amount of things getting done per step gots worse and the quality degraded too, forgetting basic things along the way a few prompts in. as I said n=1 but the very repetitive nature of my current work days alwyas doing a new thing from the exact same start point that hasn't changed in half a year is kind of my personal benchmark. YMMV but on my end the effects are real, specifically when tracking hours over this stuff.

four prompts with opus 4.6 today is equivalent to 30 or 40 two months ago. infernal downgrade in my case.

Backlash on HN for Anthropic adjusting usage limits is insane. There's almost no discussion about the model, just people complaining about their subscription.

Who cares about a new model you can’t even use?

Even using Mythos with their own benchmarks as a comparison that isn't available for most people to use, what a joke.

I did not follow all of this, but wasn't there something about, that those reasoning tokens did not represent internal reasoning, but rather a rough approximation that can be rather misleading, what the model actual does?

This comment thread is a good learner for founders; look at how much anguish can be put to bed with just a little honest communication. 1. Oops, we're oversubscribed. 2. Oops, adaptive reasoning landed poorly / we have to do it for capacity reasons. 3. Here's how subscriptions work. Am I really writing this bullet point? As someone with a production application pinned on Opus 4.5, it is extremely difficult to tell ap…

These threads are always full of superstitious nonsense. Had a bad week at the AIs? Someone at Anthropic must have nerfed the model!

The roulette wheel isn't rigged, sometimes you're just unlucky. Try another spin, maybe you'll do better. Or just write your own code.

Don't look at "thinking" tokens. LLMs sometimes produce thinking tokens that are only vaguely related to the task if at all, then do the correct thing anyways.

Not showing up in claude code by default on the latest version. Apparently this is how to set it: /model claude-opus-4-7 Coming from anthropic's support page, so hopefully they did't hallucinate the docs, cause the model name on claude code says: /model claude-opus-4-7 ⎿ Set model to Opus 4 what model are you? I'm Claude Opus 4 (model ID: claude-opus-4-7).

On the most current version (v2.1.110) of claude: > /model claude-opus-4.7 ⎿ Model 'claude-opus-4.7' not found

Sounds like it was added as of .111, so update and it might work?

As the author of the now (in)famous report in https://github.com/anthropics/claude-code/issues/42796 issue (sorry stella :) all I can say is... sigh. Reading through the changelog felt as if they codified every bad experiment they ran that hurt Opus 4.6. It makes it clear that the degradation was not accidental.

I'm still sad. I had a transformative 6 months with Opus and do not regret it, but I'm also glad that I didn't let hope keep me stuck for another few weeks: had I been waiting for a correction I'd be crushed by this.

Hypothesis: Mythos maintains the behavior of what Opus used to be with a few tricks only now restricted to the hands of a few who Anthropic deems worthy. Opus is now the consumer line. I'll still use Opus for some code reviews, but it does not seem like it'll ever go back to collaborator status by-design. :(

Gemini and Codex already scored higher on benchmarks than Opus 4.6 and they recently added a $100 tier with limited 2x limits, that's their answer and it seems people have caught on.
