Meta’s Faiss 1.16.0 Adds E-Means for Faster Large-Scale Clustering

Meta’s Faiss maintainers released version 1.16.0 on November 10, 2026, packaging FAIR at Meta’s e-means clustering algorithm with CPU, GPU and distributed implementations. The researchers report beating Lloyd k-means’ loss after 25 epochs in 1.4 to 2.6 epochs, with 10–45× GPU wall-clock speedups against the compared implementations. The software release follows the research preprint’s arXiv submission on November 6, 2026, rather than marking the algorithm’s first public disclosure. The work...
