One of the things I've been working on at Cursor is beefing up Cursor Rules. We want Agent to be as powerful as the most knowledgable person on your team. Here's how we use them at Cursor. 🧵

Just added Grok-2 support to Cursor, eagerly awaiting Grok-3 👀

Cursor is glowing up + access to latest models like Sonnet 3.7 + deep crazy solves for hardcore SWE problems You have no other choice but to use the best tool there is. And it’s just the beginning.

Cursor trained a SOTA embedding model on semantic search It substantially outperforms out of the box embeddings and rerankers used by competitors! You can see feel the difference when using agent!

One crazy stat about Cursor is we still haven't spent a dollar on marketing!

Jack is responsible for the world's best image models. Very excited to see his creativity in image-models applied to coding agents!

Grok 3 is available for all Cursor users! The mini model is available for free. Curious to hear what you think. In our initial testing, it appears to think upfront more than other models.

Cursor writes almost 1 billion lines of accepted code a day. To put it in perspective, the entire world produces just a few billion lines a day.

And ~40% of code committed by professional engineers using Cursor is generated by Cursor!

And we're adding exceptionally talented people every week! Some recent ones include: - inventor of GQA - putnam 3-time winner - principal eng behind GH search - first author of orig scaling test-time compute paper And lots more I can't mention yet 👀

Claude Sonnet 4 is much better at codebase understanding. Paired with recent improvements in Cursor, it's SOTA on large codebases

Really enjoyed this conversation! A good look into how we're training frontier models at Cursor

A conversation with a few folks from Cursor Aman Sanger, Lukas Möller, and Jacob Jackson on: - Cursor's meteoric growth - Claude 4's coding and agentic abilities - The day in the life of a SWE in 2027 - Working at a startup vs a big co - And much more!

gpt-5 vs sonnet/opus is the new vim vs emacs

The world's fastest MXFP8 MoE kernels!
