Key point
Hugging Face announced a major update to the Kernels project for packaging, distributing, and securing custom kernels.
Details
Hugging Face has unveiled a major update to the 🤗 Kernels project, which aims to standardize the packaging and distribution of custom kernels.
The key updates are as follows:
- Introduction of a new repository type: A new repository type called
kernelhas been added to the Hugging Face Hub, making it easy to discover and use kernels optimized for specific accelerators, operating systems, and backend versions. - Enhanced security architecture: To prevent risks that custom kernels could pose to local systems, build reproducibility is ensured using Nix, and the source Git SHA1 is embedded to clarify provenance.
- Trusted Publishers: For security, by default only kernels published by trusted organizations are loaded. To use untrusted kernels, you must explicitly set the
trust_remote_code=Trueoption. - Code Signing: To prevent malicious kernel distribution due to account takeover, code signing using Sigstore's cosign has been introduced to verify kernel integrity.
