Input: I want to wash my car. The car wash is 50 meters away. Should I walk or drive? Output: Walk. It'll take you under a minute, and driving 50 meters barely gets the engine warm — plus you'd just have to park again at the other end. Honestly, by the time you started the car, you'd already be there on foot. --- I asked it to figure out why it made the mistake: "Physical/spatial common sense. Exactly what just happe…

Too late, personally after how bad 4.6 was the past week I was pushed to codex, which seems to mostly work at the same level from day to day. Just last night I was trying to get 4.6 to lookup how to do some simple tensor parallel work, and the agent used 0 web fetches and just hallucinated 17K very wrong tokens. Then the main agent decided to pretend to implement tp, and just copied the entire model to each node...

We've started calling it dopus at work :(

noticing sharp uptick in "i switched to codex" replies lately. a "codex for everything" post flocking the front page on the day of the opus 4.7 release me and coworker just gave codex a 3 day pilot and it was not even close to the accuracy and ability to complete & problem solve through what we've been using claude for. are we being spammed? great. annoying. i clicked into this to read the differences and initial exp…

codex astroturfing is even bigger on Reddit.

I am honestly just happy they haven't figured out a way to lock in the users, and that there are alternatives that can get it done. I feel like they treat the user as a dumb peasant.

I haven't seen any improvement on Opus 4.6 from it (on xhigh) and it seems to often suggest and do things that just make no sense at all. For instance today I asked it to sketch out a UI mockup for for a new frontend feature and it asked me whether I wanted to make it part of the docs (it has absolutely nothing to do with the docs). I asked why it should be part of the docs and it goes "yes of course that makes no sense at all, disregard that".

4.6 has also been giving similar hallucination-prone answers for the last week or so and writing code that has really weird design decisions much more than it did when it was released.

Also whenever you ask it to do a UI it always adds a bunch of superfluous counts and bits of text saying what the UI is - even when it's obvious what it does. For example you ask it to write a fast virtualised list and it will include a label saying "Fast Virtualized List -- 500 items". It doesn't need a label to say that!

Interestingly github-copilot is charging 2.5x as much for opus 4.7 prompts as they charged for opus 4.6 prompts (7.5x instead of 3x). And they're calling this "promotional pricing" which sounds a lot like they're planning to go even higher. Note they charge per-prompt and not per-token so this might in part be an expectation of more tokens per prompt. https://github.blog/changelog/2026-04-16-claude-opus-4-7-is-...

Copilot's per-prompt pricing is crazy unsustainable. I doubt even a 2.5x increase is enough. I've had a couple of times where I've kept Copilot/Opus 4.6 occupied for a full day on a single prompt recently.

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-…

Its especially concerning / frustrating because boris’s reply to my bug report on opus being dumber was “we think adaptive thinking isnt working” and then thats the last I heard of it: https://news.ycombinator.com/item?id=47668520 Now disabling adaptive thinking plus increasing effort seem to be what has gotten me back to baseline performance but “our internal evals look good“ is not good enough right now for what ma…

Assuming /effort max still gets the best performance out of the model (meaning "ULTRATHINK" is still a step below /effort max, and equivalent to /effort high), here is what I landed on when trying to get Opus 4.7 to be at peak performance all the time in ~/.claude/settings.json: { "env": { "CLAUDE_CODE_EFFORT_LEVEL": "max", "CLAUDE_CODE_DISABLE_BACKGROUND_TASKS": "1" } } The env field in settings.json persists across…

Seems so silly that they won't support `effortLevel: "max"` while a env var is perfectly fine.

They do now. /effort command is on the latest Claude Code version; run `claude update` and `claude /effort`.

Yesterday, after testing this model, I immediately unsubscribed from Anthropic. My subscription will end in another two weeks. They are milking general consumers for their enterprise business. First, they nerfed the Claude 4.6 models a couple of weeks before launching 4.7, then released a worse, subpar model and presented it as an enhanced version. I subscribed to multiple Codex Plus plans, and they work much better than this.

You can fool some people all the time, and all people some of the time, but you cannot fool all the people all the time. for the context: I was fixing a draining test for a worker implementation in parsing engine, claude code took 1 hour with high effort at 1 AM with a broken unfixed implementation. Slept, wake up and give codex a try, it fixed in 5 minutes with a 1% of quota usage.
