Cursor Open-Sources Mixture-of-Kittens (MoK): A Deterministic MoE Training Megakernel for GB300 NVL72 Racks
Cursor Research has open-sourced Mixture-of-Kittens (MoK), the mixture-of-experts coaching megakernel behind its Composer fashions. MoK fuses each MoE communication and computation step right into a single deterministic kernel. Cursor group studies as much as 2.37x greater throughput than the strongest public baseline. It already powers Composer coaching throughout tens of hundreds of GPUs. Is it…
