Overview

Training and inference PyTorch at scale with minimal code changes

✓ Minimal code changes required to scale PyTorch training across multiple GPUs and TPUs seamlessly
✓ Handles mixed precision, gradient accumulation, and distributed training automatically without manual configuration
✓ Integrates seamlessly with Hugging Face ecosystem including Transformers and Datasets libraries
✓ Supports both single-node multi-GPU and multi-node distributed training with unified API

✗ Steep learning curve for users unfamiliar with distributed training concepts and PyTorch internals
✗ Limited debugging tools when training fails on distributed setups, making troubleshooting time-consuming
