| Installation | JAX uses the `jax` Python package and `jaxlib`, which contains compiled binaries with different builds for operating systems and accelerators. | Keras installs from PyPI with pip install --upgrade keras; using Keras 3 also requires installing a backend framework. |
| Support | The installation guide directs users with problems using prebuilt wheels to the JAX GitHub issue tracker. | The Keras site directs users to its Google Group for questions and development discussion, and GitHub issues for bug reports and feature requests. |
