Linus Torvalds says he uses AI tools for Linux kernel coding, with caution

The move is a turning point in the developer’s relationship with AI and Linux.

An anonymous reader quotes a report from ZDNet: Many open-source developers still dislike AI. The latest example is System76 banning AI-generated content from its COSMIC desktop. At Open Source Summit Europe, Linux creator Linus Torvalds offered a different take: "I actually really like using AI," Torvald told Dirk Hohndel, his good friend and head of Ericsson Software Technology, in their latest discussion. [...] Torvalds said, "I think that you need to be very careful using AI when you're doing something real and important." Torvalds explained he hadn't always felt that way about AI programming. "I used to think it was just not very good -- but now I'm at the point where I actually really like using AI." "To be fair," he continued, "I don't do a lot of kernel programming. I'm a maintainer. The Linux kernel is a project where other people do the real work, and I act as the collection point. But I still enjoy programming immensely. I think AI is a wonderful tool if you use it correctly and treat it as a tool, and I find it makes programming much more enjoyable." Torvalds recalled, "I started programming in 1981 or so, and back then computers were much simpler, and you could understand what they were doing, and also the programs you compared your own programs to were much simpler." "It's a different story today," Torvalds said. "The bar in software engineering has grown so high that it's hard to see your own small efforts as worth anything, because you're used to all these polished, professional programs. [...] A lot of people make fun of vibe coding, but I think it's a wonderful way to find joy in programming. It makes you feel like you're doing something relevant. It allows you, as a new programmer, to do things that you would otherwise have a really hard time with." He continued: "I love the concept of AI as a gateway drug because I was working on my own toy project, the guitar pedal, and I knew what I was doing. I had a user interface that I had written myself in C that was running on a microcontroller that was running on this small screen, and I was like, "This is just stupid. It looks like something from the '80s; I wanted it to look like something from this century. But I don't do Java. I do kernels." "So, I use AI to do the things that I'm bad at," Torvalds went on, "I'd seen all the same YouTube videos you have. Give AI a prompt, and it will do it. So I gave it a prompt, and it did it, and it was horrendous. Then I said, 'Hey, look! I already did this in C. I did it the right way. It's just ugly." Torvalds acknowledged that AI tools are helping identify security vulnerabilities and improve the Linux kernel, but at the cost of overwhelming maintainers with questionable bug reports and superficial fixes. He called some submissions "mindless band-aid kind of patches." That said, despite AI's growing influence, Torvalds believes Linux's success comes from steady, incremental development rather than sweeping changes. "I'm a big believer in the whole incremental small changes that, over time, turn into big features," he said. The development goal remains "incremental improvement and steady progress all the time."

After using Claude Code to draft code to help make a fundamental improvement to the Linux kernel, Linux creator Linus Torvalds continued using AI this weekend and talking up its benefits. Beyond generating initial patches and a test program for that noted I/O enhancement, he separately talked up using AI/LLMs for making patches more decipherable to understand in the process the AI noted more long-standing bugs within the Linux kernel...

Linux creator Linus Torvalds has been known to use AI to help with kernel debugging and outside of the kernel tree has also done some vibe coding with Google's Antigravity. He has previously said he views AI as a useful tool. It turns out he's even now using Claude Code for working on new Linux kernel features...
