Our latest blog presents work on Jagged Flash Attention (JFA) — the attention kernel behind @Meta's Generative Ads Model (GEM) — on @NVIDIA Blackwell (B200), built with TLX (Triton Low-level Extensions), which add explicit, hardware-aware control on top of Triton's high-level, tile-based programming model. The TLX attention kernel is about 3.2K lines of concise Triton-level code — roughly 3× less than the ~10K-line CuteDSL kernels of the state-of-the-art FlashAttention-4 (FA4), and it outperforms FA4 on the jagged shapes that matter for GEM — by ~13% on the forward pass and ~50% on the backward pass.
