It is worth noting that before rewriting in Rust, Bun maintained a fork used to accelerate the compilation and informed those who asked that this fork could never be merged due to Zig's zero-LLM policy.

A few weeks later, Bun began the Rust rewrite. Although not explicitly stated, I suspect these two events may be related.

As was mentioned countless times here on HN, the fork didn't get merged not because of any no-AI policy but because the Zig maintainers considered it to be of poor quality and were already working on more comprehensive improvements to the compiler which would bring the same (and more) benefits, but without the downsides and quality issues of the fork.
