Cursor partners with SpaceX on model training

Cursor's partnership with SpaceX aims to significantly enhance their model training efforts by utilizing xAI's Colossus infrastructure, addressing previous limitations imposed by compute constraints. Since the release of Composer less than six months ago, Cursor has achieved substantial advancements in their agentic coding model, with Composer 1.5 increasing reinforcement learning capabilities by over 20 times and Composer 2 introducing continued pretraining that delivers frontier-level performance at a reduced cost. This collaboration is expected to further scale the intelligence of Cursor's models, building on the successes of previous iterations.
