Install the latest claude code to use opus 4.7:

`claude install latest`

I have a strong feeling that this website was designed by Claude Code using the /frontend-design skill.

A Claude Code setup that implements ML papers from arxiv. Give it a paper, it orchestrates a team of AI agents to read the paper, plan the implementation, write the code, verify correctness, optimize performance, train, and compare results against the paper's claims.

The official document from Anthropic:

> Fast mode is not a different model. It uses the same Opus 4.6 with a different API configuration that prioritizes speed over cost efficiency. You get identical quality and capabilities, just faster responses.

They failed to grasp the very fundamental point of batching, which is sharing model weights between requests. For more context, this wasn't just one person's mistake, several AI twitter personalities proposed this 'Claude Opus fast = small batching' hypothesis. What I find funny is how confident these AI influencers were, while the people who actually work on LLM serving at frontier labs said nothing. The people who genuinely understand this and work at frontier labs stay quiet. The rest is simply noise.

I do think Claude Code as a tool gave Anthropic some advantages over others. They have plan mode, todolist, askUserQuestion tools, hooks, etc., which greatly extend Opus's capabilities. Agree that others (Codex, Cursor) also quickly copy these features, but this is the nature of the race, and Anthropic has to keep innovating to maintain its edge over others

For one, these models should be able to understand the physical world via images, audio, and video. I do agree that current models are quite good at coding, but that's mainly because coding is entirely text-based and easily verifiable. It's not obvious that this capability will transfer to other domains that aren't text-based and aren't as easily verifiable.

> we may have AI that is more capable than everyone in only 1-2 years

There's no evidence this will be the case...

I'm not familiar with these open-source models. My bias is that they're heavily benchmaxxing and not really helpful in practice. Can someone with a lot of experience using these, as well as Claude Opus 4.5 or Codex 5.2 models, confirm whether they're actually on the same level? Or are they not that useful in practice?

P.S. I realize Qwen3-Max-Thinking isn't actually an open-weight model (only accessible via API), but I'm still curious how it compares.

IIRC, the Claude Code creator mentioned that all the PRs are reviewed by humans, just like normal human PRs. So yes, humans still look at the code at the review stage. Though I still consider this to be level 3, but anyway, this is just a matter of definition.

I believe Anthropic is already doing Level 3 vibe coding for >90% of their code.
