The Together AI kernels team, including researchers Dan Fu and Tri Dao, developed FlashAttention, a software layer that significantly optimizes GPU performance for AI models. This breakthrough, achieved by applying database system principles to GPU memory movement, resulted in 2-3x speedups, challenging the notion that transformer attention was already fully optimized. The team's subsequent work, including the ThunderKittens library, aims to accelerate kernel development for new hardware like NVIDIA's Blackwell GPUs, addressing the critical software-hardware gap in AI infrastructure.
