JAX

Data Science, Analytics and AI/ML

JAX is a high-performance numerical computing library developed by Google that combines NumPy-like syntax with automatic differentiation and just-in-time compilation via XLA, enabling fast execution on CPUs, GPUs, and TPUs. It is heavily used by machine learning researchers and engineers for building and training neural networks, especially in research settings requiring custom gradients and transformations like vmap and pmap. It underlies libraries such as Flax and Haiku and is popular for large-scale deep learning research.
