DeepSpeed

DeepSpeed is a deep learning optimization library for PyTorch, developed by Microsoft, that significantly reduces computing resources required for training and inference of large-scale models. It provides techniques such as ZeRO (Zero Redundancy Optimizer) for memory optimization, DeepSpeed-MoE for Mixture of Experts, and high-performance inference. Currently at version 0.18.9, it maintains an active development pace with frequent patch releases addressing bug fixes, performance enhancements, and new feature integrations, often every few weeks.
