PyTorch Foundation Welcomes Helion as a Foundation-Hosted Project to Standardize Open, Portable, and Accessible AI Kernel Authoring

Helion joins community of leading open source AI projects to simplify kernel development across the open AI ecosystem

PARIS – PyTorch Conference EU – April 7, 2026 – The PyTorch Foundation, a community-driven hub for open source AI under the Linux Foundation, today announced that it has welcomed Helion as its newest foundation-hosted projects alongside DeepSpeed, PyTorch, Ray, and vLLM. This contribution by Meta addresses a critical layer of the AI stack, making kernel authoring a first-class part of PyTorch by strengthening custom kernel creation and reducing manual coding effort through autotuning.

Helion joins the Foundation as AI model development expands from training to an inference boom, elevating the importance of serving models at scale. In this landscape, in which hardware, software, and model architectures are shifting simultaneously, engineering teams face significant hurdles in cross-platform compatibility. Helion eliminates bottlenecks associated with model architectures and execution, providing developers with radically simpler kernels, automated ahead-of-time autotuning, and greater hardware performance portability.

“Helion joining the PyTorch Foundation as its newest project reflects where the open AI ecosystem needs to go next: higher-level performance portability for kernel authors,” said Matt White, Global CTO of AI at the Linux Foundation and CTO of the PyTorch Foundation. “Helion gives engineers a much more productive path to writing high-performance kernels, including autotuning across hundreds of candidate implementations for a single kernel. As part of the PyTorch Foundation community, this project strengthens the foundation for an open AI stack that is more portable and significantly easier for the community to build on.”

Helion is a Python-embedded domain-specific language (DSL) for authoring machine learning kernels, designed to compile down to multiple backends for hardware heterogeneity (Triton, TileIR, and more coming soon). Helion aims to raise the level of abstraction compared to kernel languages, making it easier to write efficient kernels while enabling more automation in the autotuning process.

In addition to Helion joining the Foundation, ExecuTorch is becoming part of PyTorch Core. Started at Meta, ExecuTorch continues to extend PyTorch model functionality for on edge and on-device environments under the Foundation, ensuring that ecosystem and technical decisions are made in an open, community-guided manner.

Developers and contributors interested in participating in the PyTorch project ecosystem are encouraged to join the community onsite at upcoming events like PyTorch Conference China (Shanghai, September 8-9) and PyTorch Conference North America (San Jose, October 20-21).
