Orbax is an open-source checkpointing and persistence library for JAX, developed by Google. It provides utilities to save and restore model weights and state (pytrees), supporting asynchronous checkpointing, custom types, and flexible storage formats. It is used by JAX-based machine learning frameworks such as Flax, PaxML, and T5X, and is available as domain-specific PyPI packages (orbax-checkpoint and orbax-export).
Saves model weights and restores them into a fresh model for verification and text generation.
