A Hitchhiker's Guide to the Array API Standard Ecosystem
summary
The project claims a practical unification of Python array libraries so NumPy CuPy PyTorch JAX and Dask interoperate; it ships a test suite and wrappers and shows SciPy and scikit‑learn running under an experimental flag using array_api_compat, CI that runs GPU jobs and compliance checks via array_api_strict, plus a portable xp namespace and utility pack array_api_extra. Implementation work is five years in, yields reported orders‑of‑magnitude GPU speedups for some workloads, and is already usable though still expanding coverage and typing support.
