Last day at Cursor. An incredible place. Stopped by for coffee, they gave me a keyboard that afternoon, and started helping out on Composer the next week. Feel lucky to have worked with such a fearless and ambitious team. https://t.co/gh8FnzBudF 62.3K views · 1.2K likes · 12 reposts · 68 replies 24 Aug 2026 · Open on X →

Spending some time in Cambridge MA next week. Happy to grab coffee. Things I’m kind of interested in: cool things to do now that proofs are cheap, things RL can’t do, views on what the heck CS is now. 22.4K views · 198 likes · 2 reposts · 10 replies 21 Aug 2026 · Open on X →

The kernel folks are living on the front-lines. Where the the "cognitive abstractions" should live in a stack is such an interesting question. 33.8K views · 222 likes · 10 reposts · 6 replies 05 Aug 2026 · Open on X →

Jax added support for opaque types with custom tangents. One cool use is proper handling of batched geometric objects. Here's a short demo of a differentiable rasterization, i.e. min L2 w/ 1500 triangles to a photo. Interesting to move beyond tensors.

It's really neat to see all the interest in the Composer 2 technical report, from training to kernel design to inference. If you have any questions about why we did things, feel free to ask. I'll run around the office and bug people. 60.6K views · 321 likes · 18 reposts · 35 replies 25 Mar 2026 · Open on X →
