Cursor releases open-source MoE training megakernel, Mixture-of-Kittens

By PulseAugur Editorial · [5 sources] ·

Cursor Research has open-sourced Mixture-of-Kittens (MoK), a specialized training kernel designed for Mixture-of-Experts (MoE) models. This megakernel fuses MoE communication and computation into a single deterministic process, reportedly achieving up to 2.37x higher throughput compared to existing baselines. MoK is optimized for high-end hardware like NVIDIA GB200 NVL72 racks, making it suitable for large-scale AI model development and training. AI

IMPACT Accelerates training for large MoE models on high-end hardware, potentially speeding up development cycles for advanced AI.

RANK_REASON Cursor Research open-sourced a specialized training kernel (Mixture-of-Kittens) for MoE models, which is a software tool rather than a new frontier model release.
