I think you cannot find any because the Linux kernel itself has AI assisted development happening. Distros that use the kernel then cannot say "No AI."

Edit: Gentoo and NetBSD specifically do not allow AI generated code.

If you are ok with Ubuntu in general, excluding the AI part, go upstream and get Debian. It's primarily mandate is stability which, to me at least, means no AI integration from the standard install.

Hop on Arch.

See the other comment about the kernel, but that aside you could go down the https://www.linuxfromscratch.org/ route

https://secureblue.dev/contributing#ai-content

In the interest of accuracy, quality, and license of the project, contributing using AI generated code and content of any kind is forbidden.

I feel that and I hope we get there one day, but for now it might be better to stick with a distro that has a proven track record of good maintainers properly reviewing code. You're searching for a daily driver for your machine, right? Or is it a more specialized use case?

Simply saying “No AI” would forbid a huge amount of code that was written with assistive technologies that long precede the latest crop of proprietary LLMs; I'd venture it would cover almost all software in distributions for the past several decades.

“AI” is a marketing term, in continuous use from the mid-twentieth century to encompass a broad and ever-changing range of automation and other tools, that is deliberately vague. If we want to be clear what the ban does and does not cover, we need to avoid that term.

And then of course we can deliberate on exactly what is permitted (code that was auto-corrected by a spell checker? code that had its boilerplate syntax automatically generated?) versus what is forbidden (code that was generated in some proprietary data centre? code that is an unattributable, non-consensual remix of existing code? code that was probabilistically extruded from an LLM?), because we'll avoid the useless term “AI” and instead speak of specific tools and technologies.

No linux distro advertises as "AI-free" because that's a bit like saying a burger is uranium-free

I think Artix is against AI. I'd have to double-check that.

I can make one for you, won't have any mistakes, just give me few hours

Debian? Fedora? Bazzite?

If it ever got to the point that all distros had in-your-face-AI I'll turn my Pixel/GrapheneOS phone into a "desktop" computer. Just have to connect a hub, monitor, keyboard and mouse and take advantage of the pass-through charging.
