DeepSpeed
DeepSpeed is a framework maintained by PyTorch Foundation (hosted project)68 and DeepSpeed Technical Steering Committee (project committers)3. Its source code is public1 under the Apache License 2.023.
DeepSpeed is an open-source PyTorch library for distributed training and inference of large models; its features include the ZeRO memory optimizations, 3D parallelism, Ulysses sequence parallelism, and mixture-of-experts support. Microsoft contributed it to LF AI & Data as an incubation project in February 2025, and in May 2025 it became a hosted project of the PyTorch Foundation, which names Microsoft as the contributor.1967
