JAX stands out by combining automatic differentiation with hardware acceleration, making it ideal for researchers and developers who need both speed and flexibility in their machine learning workflows.

When it fits — and when it doesn’t

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited support for certain hardware accelerators beyond NVIDIA GPUs

   Documentation and community resources are sparse for AMD or Intel GPU setups

2. 02

   Complex setup process, especially for distributed computing environments

   Requires manual configuration of XLA flags and dependencies which can be error-prone

What it does well

• Automatic differentiation (Autograd)

• Hardware acceleration with XLA

• Comprehensive math and linear algebra operations

• Support for GPU and TPU

• High-performance array manipulation
