Extreme Speed and Scale for DL Training and Inference
DeepSpeed enables world’s most powerful language models like MT-530B and BLOOM. It is an easy-to-use deep learning optimization software suite that powers unprecedented scale and speed for both training and inference. With DeepSpeed you can:
- Train/Inference dense or sparse models with billions or trillions of parameters
- Achieve excellent system throughput and efficiently scale to thousands of GPUs
- Train/Inference on resource-constrained GPU systems
- Achieve unprecedented low latency and high throughput for inference
- Achieve extreme compression for an unparalleled inference latency and model size reduction with low costs
DeepSpeed has four innovation pillars:
DeepSpeed offers a confluence of system innovations, that has made large-scale DL training effective, and efficient, greatly improved ease of use, and redefined the DL training landscape in terms of scale that is possible. These innovations such as ZeRO, 3D-Parallelism, DeepSpeed-MoE, ZeRO-Infinity, etc fall under the DeepSpeed-Training pillar. Learn more: DeepSpeed-Training
DeepSpeed brings together innovations in parallelism technology such as tensor, pipeline, expert and ZeRO-parallelism, and combines them with high-performance custom inference kernels, communication optimizations and heterogeneous memory technologies to enable inference at an unprecedented scale, while achieving unparalleled latency, throughput and cost reduction. This systematic composition of system technologies for inference falls under the DeepSpeed-Inference. Learn more: DeepSpeed-Inference
To further increase the inference efficiency, DeepSpeed offers easy-to-use and flexible-to-compose compression techniques for researchers and practitioners to compress their models while delivering faster speed, smaller model size, and significantly reduced compression cost. Moreover, SoTA innovations on compression like ZeroQuant and XTC are included under the DeepSpeed-Compression pillar. Learn more: DeepSpeed-Compression
In line with Microsoft’s mission to solve humanity’s most pressing challenges, the DeepSpeed team at Microsoft is responding to this opportunity by launching a new initiative called DeepSpeed4Science, aiming to build unique capabilities through AI system technology innovations to help domain experts to unlock today’s biggest science mysteries.

DeepSpeed Software Suite
The DeepSpeed library implements and packages the innovations and technologies in DeepSpeed Training, Inference and Compression Pillars into a single easy-to-use, open-sourced repository. It allows for an easy composition of a multitude of features within a single training, inference or compression pipeline. The DeepSpeed Library is heavily adopted by the DL community, and has been used to enable some of the most powerful models (see DeepSpeed Adoption).
Model Implementations for Inference (MII)
Model Implementations for Inference (MII) is an open-sourced repository for making low-latency and high-throughput inference accessible to all data scientists by alleviating the need to apply complex system optimization techniques themselves. Out-of-box, MII offers support for thousands of widely used DL models, optimized using DeepSpeed-Inference, that can be deployed with a few lines of code, while achieving significant latency reduction compared to their vanilla open-sourced versions.
DeepSpeed on Azure
DeepSpeed users are diverse and have access to different environments. We recommend trying DeepSpeed on Azure as it is the simplest and easiest method. The recommended method to try DeepSpeed on Azure is through AzureML recipes. The job submission and data preparation scripts have been made available here.
