The Zig project's rationale for their firm anti-AI contribution policy
Zig's strict anti-LLM contribution policy (banning LLM use for issues, PRs, and comments) is rooted in valuing long-term human contributors over code. Loris Cro explains that reviewing LLM-written PRs does not help grow new trusted project members. As a consequence, Bun—a major Zig-based project—will not upstream performance improvements due to this ban.
