Stay with 4.6 if you can, it is disabled (afaik) on vscode claude code extension.

4.7 IMO is around 10-20% worse at understanding your prompt intention. You need more effort to explain your intention clearer so it doesn't divert.

Same. 4.7 intelligence is significantly worse than 4.6 on ALL 3P Harnesses. So only on Claude Code and Anthropic API/Subscription you get decent performance but on every other Harness and/or Cloud Provider inference (Bedrock) it performs worse than 4.6 on almost every task. This is not just anecdotal, i've talked to many colleagues from AWS, Microsoft and so on and they all agree that something fishy is going on.

I switched back to even Sonnet 4.6 in Claude Code over Opus 4.7. Every day or two I try a new task on Opus 4.7 and regret it.

Looking now I see that "Opus 4.6 Legacy" is an option that was not there before, so maybe Anthropic noticed that others are having the same difficulty.

Never used 4.7 outside CC extension VSCode. TIL, will keep that in mind

I was recently talking to someone about that! I wasn't sure if it was my imagination, but I felt like Opus 4.6 was way more diligent about looking things up online and making sure that its response was accurate. While Opus 4.7 seems content to just throw out an answer as quickly as possible with little care for accuracy; I started to always remind it to do an online search and to double check its work, to the point where I had to add a custom memory.

I switched back to 4.6 thinking, as most did, 4.7 introduced some jankinesss to it. I switched back soon enough to 4.7. I think I might've adapted myself to what and how 4.7 does things. 4.6 felt a step backward.

[fendy3002]

4.7 is better if your spec is clearer. 4.6 is better if you give it more freedom doing it's tasks. 4.6 felt it'll steer off often if you give detailed specs than 4.7 though, so perhaps that's it

[meowface]

Agreed. 4.7 is a smarter but weirder model. It will get confused in unexpected ways, but when it's not confused it will perform better than 4.6.

It's not a bad idea to skip it and wait until the next model release, but I personally will stick with 4.7.

How does their versionimg work? Because I've assumed that they're constantly tweaking their system prompts, I'm hoping in a couple of months, 4.7 will be improved over my first impressions- I caught significant hallucinations, something I'd rarely experienced with 4.6, if at all, I honestly can't remember one - but what I worried me was thebout the hallucinations I didn't catch.

That is a load-bearing decision!

That’s a decision-shaped comment.
