**Helion** is a Python-embedded domain-specific language (DSL) for
authoring machine learning kernels, designed to compile down to [Triton],
a performant backend for programming GPUs and other devices. Helion aims
to raise the level of abstraction compared to Triton, making it easier
to write correct and efficient kernels while enabling more automation
in the autotuning process.

[Triton]: https://github.com/triton-lang/triton

The name *Helion* refers to the nucleus of a helium-3 atom, while *Triton*
refers to hydrogen-3.

Helion can be viewed either as *PyTorch with tiles* or as *a hig
