Cursor is partnering with SpaceX to accelerate our model training efforts.
We released Composer less than six months ago as our first agentic coding model.
After that, Composer 1.5 scaled reinforcement learning by over 20x. Composer 2 then added continued pretraining, reaching frontier-level performance at a fraction of the cost of other models. Each step up in compute has translated to meaningfully more capable models.
We've wanted to push our training efforts much further, but we've been bottlenecked by compute. With this partnership, our team will leverage xAI's Colossus infrastructure to dramatically scale up the intelligence of our models.
