Linux creator uses Claude Code assistant for kernel update

Linus Torvalds, the creator of Linux, recently utilized Anthropic's Claude Code assistant to help build and test a set of code changes for the operating system kernel. According to a report from tech outlet Phoronix, a public code repository managed by Torvalds revealed a new branch containing modifications aimed at speeding up how systems handle memory caching. Torvalds explicitly credited the AI tool in his patch notes for helping write code, generate tests, and draft documentation under his guidance.

This update matters because Linux powers a massive portion of the world's digital infrastructure, including cloud servers, Android devices, and supercomputers. The specific fix targets a bottleneck where multiple software processes slow down when trying to read small pieces of data simultaneously. Seeing the software industry's most famous skeptic of poor code embrace automated coding tools suggests that AI assistants have reached a level of reliability capable of handling ultra-complex core system tasks.

It remains to be seen whether this experimental code will officially make it into the next main Linux release. Moreover, open source projects now face an important question about how maintainers will vet code generated by AI when even top experts rely on automated tools to speed up their workflow.
