The naming scheme used to be "Claude [number] [size]", but now it is "Claude [size] [number]". The new models should have been named Claude 4 Opus and Claude 4 Sonnet, but they changed it, and even retconned Claude 3.7 Sonnet into Claude Sonnet 3.7.

Annoying.

3.7 failed when you asked it to forget react, tailwindcss and other bloatware. wondering how will this perform.

well, this performs even worse... brrrr.

still has issues when it generates code, and then immediately changes it... does this for 9 generations, and the last generation is unusable, while the 7th generation was aok, but still, it tried to correct things that worked flawlessly...

“GitHub says Claude Sonnet 4 soars in agentic scenarios and will introduce it as the base model for the new coding agent in GitHub Copilot.” Maybe this model will push the “Assign to CoPilot” closer to the dream of having package upgrades and other mostly-mechanical stuff handled automatically. This tech could lead to a huge revival of older projects as the maintenance burden falls.

Anyone see news of when it’s planned to go live in copilot?

The keynote confirms it is available now.

I've found myself having brand loyalty to Claude. I don't really trust any of the other models with coding, the only one I even let close to my work is Claude. And this is after trying most of them. Looking forward to trying 4.

Gemini 2.5 Pro replaced Claude 3.7 for me after using nothing but claude for a very long time. It's really fast, and really accurate. I can't wait to try Claude 4, it's always been the most "human" model in my opinion.

Gemini is _very_ good at architecture level thinking and implementation. I tend to find that I use Gemini for the first pass, then switch to Claude for the actual line-by-line details. Claude is also far superior at writing specs than Gemini.

This is exactly my approach. Use Gemini to come up with analysis and a plan, Claude to implement.

What’s your guess on when Claude 4 will be available on AWS Bedrock?

The blog says it should be available now but I'm not seeing it. In Vertex AI it's already available.

> Finally, we've introduced thinking summaries for Claude 4 models that use a smaller model to condense lengthy thought processes. This summarization is only needed about 5% of the time—most thought processes are short enough to display in full. This is not better for the user. No users want this. If you're doing this to prevent competitors training on your thought traces then fine. But if you really believe this is…

If _you_ really believe this is what all users want, _you_ should reconsider. Your describing a feature for power users. It should be a toggle but it's silly to say it didn't improve UX for people who don't want to read strange babbling chains of thought.

You're accusing me of mind reading other users, but then proceed to engage in your own mind reading of those same users.

Have a look in Gemini related subreddits after they nerfed their CoT yesterday. There's nobody happy about this trend. A high quality CoT that gets put through a small LLM is really no better than noise. Paternalistic noise. It's not worth reading. Just don't even show me the CoT at all.

If someone is paying for Opus 4 then they likely are a power user, anyway. They're doing it for the frontier performance and I would assume such users would appreciate the real CoT.

> we’ve significantly reduced behavior where the models use shortcuts or loopholes to complete tasks. Both models are 65% less likely to engage in this behavior than Sonnet 3.7 on agentic tasks Sounds like it’ll be better at writing meaningful tests

One strategy that also works is to have 2 separate "sessions", have one write code and one write tests. Forbid one to change the other's "domain". Much better IME.

Using Claude Opus 4, this was the first time I've gotten any of these models to produce functioning Dyalog APL that does something relatively complicated. And it actually runs without errors. Crazy (at least to me).

It feels as if the CPU MHz wars of the '90s are back. Now instead of geeking about CPU architectures which have various results of ambigous value on different benchmarks, we're talking about the same sorts of nerdy things between LLMs.

History Rhymes with Itself.
