We’re thrilled that FlashInfer won a Best Paper Award at MLSys 2025! 🎉 This wouldn’t have been possible without the community — huge thanks to @lmsysorg’s sglang for deep co-design (which is crtical for inference kernel evolution) and stress-testing over the years, and to

Check out the intra-kernel profiler in flashinfer to visualize the timeline of each SM/warpgroup in the lifecycle of a CUDA persistent kernel: github.com/flashinfer-ai/… You can clearly understand how tensor/cuda cores overlapping, variable length load-balancing and fusion works.

LLM is not all about tensor cores. categorical sampling under filters (top-p/top-k/min-p) are critical operators in llms as vocabulary size grows, flashinfer uses sorting-free rejection sampling algorithm for efficient sampling. checkout this great blog post written by @0xsling0

MLC-LLM now supports deploying Llama-2-70B-chat locally (needs an Apple Silicon Mac w/ 50GB VRAM to run).🦙💬🔥 The decoding speed can achieve ~10.0 tokens/s on an M2 Ultra! Try it out at: mlc.ai/mlc-llm/docs/g… and join our discord server: discord.gg/9Xpy2HGBuD

(2/4) We analyzed attention kernels' performance bottleneck for different use cases, for example, grouped query attention has high operational intensity than original multi-head attention, and GQA's performance will be bounded by low CUDA Cores performance and we propose to use
