It's important to understand that he's talking about a specific set of models that were release around november/december, and that we've hit a kind of inflection point in model capabilities. Specifically Anthropic's Opus 4.5 model.

I never paid any attention to different models, because they all felt roughly equal to me. But Opus 4.5 is really and truly different. It's not a qualitative difference, it's more like it just finally hit that quantitative edge that allows me to lean much more heavily on it for routine work.

I highly suggest trying it out, alongside a well-built coding agent like the one offered by Claude Code, Cursor, or OpenCode. I'm using it on a fairly complex monorepo and my impressions are much the same as Karpathy's.

People have said this about every single model release.

  • I had the same reaction. So when people were talking about this model back in December, I brushed it off. It wasn't until a couple weeks ago that I decided to try it out, and I immediately saw the difference.

    My opinion isn't based on what other people are saying, it's my own experience as a fairly AI-skeptical person. Again, I highly suggest you give it an honest try and decide for yourself.
