Introduction

AXLearn is a library built on top of JAX and XLA to support the development of large-scale deep learning models.

AXLearn takes an object-oriented approach to the software engineering challenges that arise from building, iterating, and maintaining models. The configuration system of the library lets users compose models from reusable building blocks and integrate with other libraries such as Flax and Hugging Face transformers.

AXLearn is built to scale. It supports the training of models with up to hundreds of billions of parameters across thousands of accelerators at high utilization. It is also designed to run on public clouds and provides tools to deploy and manage jobs and data. Built on top of GSPMD, AXLearn adopts a global computation paradigm to allow users to describe computation on a virtual global computer rather than on a per-accelerator basis.

AXLearn supports a wide range of applications, including natural language processing, computer vision, and speech recognition and contains baseline configurations for training state-of-the-art models.
