DeepSpeed is an open‑source deep learning optimization library that enables efficient distributed training and inference of large models. It provides features such as ZeRO, 3D parallelism, and mixed‑precision support for PyTorch workloads.

Use cases

• scale PyTorch models to billions of parameters across multiple GPUs
• train large language models with limited GPU memory using ZeRO offloading
• accelerate transformer training with pipeline and model parallelism
• run mixed‑precision training for faster convergence on GPU clusters
• perform efficient inference of massive models on heterogeneous hardware

When to choose

• You need to train or fine‑tune very large models (hundreds of billions of parameters).
• Your workload requires multi‑node, multi‑GPU scaling with minimal code changes.
• You want to leverage advanced memory‑saving techniques like ZeRO and offloading.

When to avoid

• Your model is small and fits comfortably in a single GPU’s memory.
• You prefer a lightweight training loop without additional dependencies.
• You are not using PyTorch or need support for other deep‑learning frameworks.
