Meet Flash-KMeans: An IO-Aware, Exact K-Means That Runs Over 200× Faster Than FAISS on GPUs
Quick Answer
Flash-KMeans is an open-source, IO-aware k-means implementation that operates over 200× faster than FAISS on NVIDIA H200 GPUs.
Quick Take
It achieves 17.9× end-to-end and 33× speedup over cuML by optimizing distance calculations and updating mechanisms without approximating results. This advancement significantly enhances performance for data scientists and machine learning practitioners.
Key Points
- Flash-KMeans uses Triton GPU kernels for efficient k-means clustering.
- Eliminates distance-matrix materialization with FlashAssign for faster processing.
- Sort-Inverse Update reduces atomic contention, enhancing performance.
- Achieves 17.9× speedup end-to-end and 33× over cuML.
- Over 200× faster than FAISS, revolutionizing k-means implementations.

Z.ai has launched GLM-5.2, featuring a 1-million-token context window and two levels of thinking effort (High and Max). The model integrates with Claude Code, Cline, and OpenClaw via an Anthropic-compatible endpoint, but no benchmarks were provided at launch, with MIT open weights expected next week.
