ZeRO-Infinity breaks the GPU memory wall for extreme-scale AI training
Microsoft researchers introduced ZeRO-Infinity to combine GPU, CPU, and NVMe memory for training models at unprecedented scale; Microsoft later documented DeepSpeed integration with Azure Machine Learning, Hugging Face, and PyTorch Lightning.
Why it moved the index
The original dated result materially lowered hardware and engineering barriers to training trillion-scale models. Separately dated Microsoft and Hugging Face evidence documented practical integration into widely used tooling, satisfying the downstream-impact requirement and supporting a direct competitive-acceleration nexus.
