Asymmetric hardware scaling is here. Blackwell tensor cores are now so fast, exp2 and shared memory are the wall. FlashAttention-4 changes the algorithm & pipeline so that softmax & SMEM bandwidth no longer dictate speed. Attn reaches ~1600 TFLOPs, pretty much at matmul speed! joint work w/ Markus Hoehnerbach, Jay Shah(@ultraproduct), Timmy Liu, Vijay Thakkar (@__tensorcore__ ), Tri Dao (@tri_dao) 1/




Excited to finally share this! It was an amazing collaboration with @andyfang and the @DoorDash team! We’re thrilled to continue partnering with one of the most innovative and execution-focused AI teams in the world.

We partnered with @DoorDash to train a proprietary RL-powered agent that encodes internal QA standards into an automated grader, turning expert judgment into a scalable training signal. The result: a 30% relative reduction in critical menu errors and a production system now live across all US menu traffic. appliedcompute.com/case-studies/d…
