DeepSpeed

Information

DeepSpeed is Microsoft’s framework for efficient distributed training of very large models. It is well known for its ZeRO optimization stages (1 to 3), which distribute parameters, gradients, and optimizer state across multiple GPUs so larger models can be trained more efficiently.

It is especially relevant for very large models, including 70B+ scale workloads that may need to offload part of the memory demand to CPU or NVMe.

Common use cases

Practical note

DeepSpeed becomes especially important when model size and memory pressure are the main bottlenecks. It is less about beginner simplicity and more about scale, efficiency, and systems-level control.
