About DeepSpeed

DeepSpeed is an open-source deep learning optimization library that enables efficient and scalable distributed training and inference of large models. Developed by the DeepSpeed team, it includes system innovations such as ZeRO (Zero Redundancy Optimizer) for memory optimization, ZeRO++ for improved communication, SuperOffload for offloading to superchips, ZenFlow for stall-free offloading, Muon optimizer support, DeepSpeed Core API with PyTorch-style backward and low-precision master states, DeepNVMe for affordable I/O scaling, DeepCompile for compiler optimization, AutoTP for automatic tensor parallelism, and Ulysses-Offload for long context training. It has powered models like MT-530B and BLOOM, and offers regular office hours for community engagement.
