Redox OS has adopted a Certificate of Origin policy and a strict no-LLM policy

“Contributions generated by large language models will not be accepted. Contributors must sign a Developer Certificate of Origin attesting to authorship.”

Redox is small enough that they can enforce this. The big projects, Linux included, have already given up. The interesting question is whether a no-LLM policy is even verifiable two years from now when the tools are wired into every IDE by default. Probably not. But drawing the line is itself the point. Some projects still care about who wrote the code.
