Opus 5.5 is our favorite AI model (so far).

AI news this week: Claude Opus 5.5 is INSANE and we love it. Faster, cheaper, better. So much for the AI slowdown. Oh and OpenAI's new thing is good too.

On today's AI For Humans, Kevin Pereira and Gavin Purcell go hands on with Claude Opus 5.5, which might be the best model we've ever used (for now). Anthropic says it hits Fable-level performance on most things at about 40% less cost than Opus 5, the writing is clearer, and yes, the five hour usage limits went up and you can now bank your resets. Then we get into what people are already making with it: a guitar store sim, a music-based side-scroller, a Mario Kart benchmark, an underwater exploration game in 3MB, claymation built in Blender, a pop punk single made entirely in code and a lot of very juicy animations.

Also: OpenAI answered with GPT-6 Sol and GPT-6 Luna, two new models that are faster and a lot cheaper than what came before. We compare them with Opus 5.5 (robot hands drawing, pelicans on bicycles in Blender), wonder what OpenAI has lined up for DevDay, and talk about Bel, the reported secret model that's beating the math. Oh, and there's a new Grok. Grok 4.7. It's out. (crickets)

Plus: Gavin used Meshy 7.1 to turn a few photos of himself into a rigged, animated 3D model and then built Gavin At Large with his Opus 5.5 agent, a game where a giant Gavin wrecks a lil town. In Actually Useful AI, GPT-6 Astra makes simple motion graphics for a real book trailer. And in AI See What You Did There: Dario vs Sam in a very weird gun fight showdown and what happens when you point Claude at the Moving Image Archive.

AI SLOWDOWN? NEVER HEARD OF HER.
