Linus Torvalds uses AI for Linux kernel patch, reports 23x speedup

Linus Torvalds, the creator of the Linux kernel, has publicly shared his first patch developed with the assistance of an AI coding tool, Claude Code. This patch addresses a performance issue related to memory management and cache contention, with initial synthetic benchmarks showing a significant, though not fully representative, performance leap. Torvalds has affirmed his support for AI tools in kernel development, viewing them as comparable to compilers and editors, provided developers understand their use and implications. AI

IMPACT Demonstrates AI's growing capability in complex software development, potentially accelerating kernel improvements and setting a precedent for AI-assisted coding in critical open-source projects.

RANK_REASON Linus Torvalds, a prominent figure in open-source development, has used an AI tool for a significant code contribution to the Linux kernel, showcasing AI's practical application in software development.
