MiniMax AI has developed a new M3 kernel for the Blackwell platform, utilizing a KV-stationary design to optimize long-context sparse attention. This kernel aims to overcome the speed limitations caused by data-dependent block selection in sparse attention models. By reading each selected block only once, the system achieves approximately 980 TFLOP/s on Nvidia's B200 hardware, preserving the theoretical gains of sparse attention. AI
IMPACT Optimizes long-context sparse attention, potentially improving efficiency and speed for large language models.
RANK_REASON The item details a technical optimization for AI model inference, specifically a new kernel design for sparse attention. [lever_c_demoted from research: ic=1 ai=1.0]
