XLA

OpenXLA project

XLA (Accelerated Linear Algebra) is a machine learning compiler that takes models from PyTorch, TensorFlow and JAX and optimizes them for execution on CPUs, GPUs and ML accelerators. It sits inside those frameworks rather than being invoked directly, so the repository is aimed at compiler contributors and at integrators adding front ends or hardware backends.

Openness

5 high confidence
5.0
license
Apache-2.0(OSI)
source
public
core-gated
ungated

Apache-2.0 license body confirmed. The repository is public and unarchived and builds the whole product, and the README describes no paid tier, enterprise edition or license-gated build beside it, so source is public and the core ungated.

Adoption

2 low confidence
2.0

4,477 GitHub stars, which lands in the 1K-10K stars band of the stars scale, level 2. XLA ships inside the frameworks that embed it rather than as its own package, so no download channel measures it and the stars scale is the instrument of last resort. Its real reach is that of PyTorch, TensorFlow and JAX, which the stars figure does not capture; a stars-derived band may not claim above 3 and this one does not.

Capability

5 medium confidence
5.0

Banded on the category feature matrix as retargetable end-to-end compiler. Placed level with the apache-tvm anchor, on a matrix that bands on how much of the model-to-hardware transformation pipeline a product performs, over how many inputs and targets.

  • https://github.com/openxla/xla/blob/main/README.md recorded 2026-08-18

    README still documents an ML compiler for GPUs, CPUs and ML accelerators that takes models from PyTorch, TensorFlow and JAX and optimizes them for execution across hardware platforms.
