Zephon Enhances TorchTitan Data Loading for PyTorch
PyTorch's TorchTitan now includes Zephon, enabling deterministic data loading for distributed model training with elastic scaling. This feature allows training to continue on a different GPU count while preserving identical data batches and loss progression. Zephon performs real-time tokenization and packing, eliminating the need for pre-processed data files.
