I just realized Opus 5.5 can use Blender to make claymations with just a single prompt in claude dot ai now

I've been on a Blender kick with Opus 5.5. Its better 3D modeling and vision mean you can build an entire world from a single prompt. Historically accurate San Francisco Market street in 1906, pre-earthquake

Using Opus 5.5 feels like hitting every green light on your drive home, drinking a cold glass of water when you're thirsty, and a hot shower after a long day. It's super smart, it writes clearly, it's fast, and it costs way less. It's a very good model.

Lots more coming soon. Today is just the start!

Sonnet 5.5 has the same feel I liked about Opus 5.5. It writes clearly, it's very fast, and it's a major capabilities jump over Sonnet 5. Really great model to iterate with.

The team did an amazing job with this merge. The resulting UX feels so much better than chat or Cowork did on their own. And the new slides/docs/design integrations work very well.

Worth spending a few minutes this weekend to read this essay in full. Embedded evaluators might sound unusual in tech but it's pretty normal in other industries. Big banks have federal examiners with desks in the building and every nuclear plant in the US has inspectors who work on site full time. I think frontier AI labs should work the same way and this is a very practical first step.

For reference, Haiku 4.5 came out on October 15th, 2025 so these two columns are less than a year apart. and oh yeah Haiku 5.5 is also much faster and 75% cheaper...

Ultra has a better ring to it than Max 20x. Also no more 5 hour rate limits for Ultra subs.

One side quest that would be so much fun to try right now is running a bunch of local small businesses with AI helping you out I think products like Claude Duet could end up being bigger for these businesses than even things like Square or Google Maps were
