This policy is straightforward and shouldn't be particularly controversial (I'm sure it will be bikeshedded to death though). It basically bans the obvious stuff ("don't just drop LLM generated comments onto PRs") and allows the important stuff like LLMs writing code so long as you disclose.edit: Wow people did not read the policy. It's literally just "if you use an LLM you are responsible for it, we will reject low quality PRs, please disclose that you have used an LLM". This is bog standard.

Some of these are just straight up unhinged.> Using an LLM to discover bugs, as long as you personally verify the bug, write it up yourself, and disclose that an LLM was used.
What are they going to do go back and reject a bug if someone later admits they found it with an LLM? Honestly they and most other project would probably be better off just ignoring the situation until norms start developing.

The assumption here is that people act in good faith. If you break the rules, this indicates that you are not acting in good faith, and perhaps should no longer be welcome.by saagarjha

What are you even talking about lol the policy doesn't imply that at all.That's in the "allowed with caveats" section. It's just saying to not open bug reports without first reading them yourself or your bug may be closed. No one is saying "by policy we will have to add the bug back in" jesus christ
The policy is insanely straightforward, idk how you can be misinterpreting it this badly. It's just "Disclose that you use a model, you are on the hook for reviewing model output as a human" and then some clear cut examples.

Here are the actual policies, not a comment:https://github.com/jyn514/rust-forge/blob/llm-policy/src/pol...
It's in-line with the 'nanny' stereotype of the Rust community that they give you permission to act in a way they would never be able to verify anyways:
> The following are allowed. > Asking an LLM questions about an existing codebase. > Asking an LLM to summarize comments on an issue, PR, or RFC...
Like seriously, what's the point of explicitly allowing this? Imagine the opposite were true, you weren't allowed to do this - what would they do? Revert an update because the person later claimed they checked it with an LLM?
The Linux policy on this is much superior and more sensible.

> Like seriously, what's the point of explicitly allowing this?Explicit permission can be useful to preemptively cut off some questions from well meaning people who, acting in good faith, might otherwise pester for clarification (no matter how silly / "obvious" it might otherwise be), or get agitated by misconstruing an all-banned list as being an overly verbose "no LLMs ever" overreach.
> It's in-line with the 'nanny' stereotype of the Rust community that they give you permission to act in a way they would never be able to verify anyways: [...]
Many of us work or have worked in corporate settings where IT takes great pains to help detect and prevent data exfiltration, and have absolutely installed the corporate spyware to detect those kinds of actions when performed on their own closed source codebases. Others rely on the honor system - at least as far as you know - but still ban such actions out of copyright/trade secret concerns. If you're steeped deeply enough in that NDA-preserving culture, a reminder that you've switched contexts might help when common sense proves uncommon.
While nannying can be obnoxious, I'm not sure that having a document one can point to/link/cite, to allay any raised concerns, counts.

What they're trying to avoid is a lot of unnecessary conflict with zealous anti-AI people calling for your exclusion for admitting to doing these things. There are people who would ban this too.

> Like seriously, what's the point of explicitly allowing this? Imagine the opposite were true, you weren't allowed to do this - what would they do?Imagine if they just say "LLMs are banned" then there's a lot of ambiguity. So they specifically outlined that generative uses of LLMs are banned, and that non-generative ones are not banned (i.e. "allowed").
I think it's a poor choice of words on their part, but it makes sense (considering what their policy is). It's more of a "we're not disallowing use in these particular scenarios, so you can still use LLMs for these if you want". Remember: it's a big project, and if they don't explicitly state something then people will ask and waste everyone's time.

If anything, it reads to me as a proactive rebuttal of complaints that they don't allow LLMs; they're definitively stating that they do allow using them for very specific purposes.by saghm
5/15/2026 at 8:40:58 AM
They're just giving examples of what you can do and explicitly saying so. Saying "you couldn't stop me" is completely missing the point.This is not very different from the Linux kernel's policy so it's an odd comparison. It's actually almost identical in practical terms.
edit: lol proof that this doc needs to be stupidly explicit is in the pudding with the HN comments going out of their way to radically misread it

On a general note, I like vouch by mitchellh.> People must be vouched for before interacting with certain parts of a project (the exact parts are configurable to the project to enforce).
https://github.com/mitchellh/vouch
I think many projects will adopt this instead of allowing everyone / blocking everyone
Many projects have "ai slop" check in place to directly close and ban user if it is "ai slop". Else, it will be hard to handle the velocity of PRs
by prashantk_
5/15/2026 at 7:55:15 AM

by staticassertion
5/15/2026 at 4:03:04 AM
But one of the reasons they switched was because the compiler upstream for the original language they used, Zig, wouldn't accept slop contributions they wanted to make for Bun perf. What will they do when they need to try to push a slop contribution upstream to rust?At this point they will probably just fork yet again and maintain some vibe compiler.

5/15/2026 at 5:47:44 AM
Huh. I wonder if the original intent was to merge an AI generated PR to a high-profile project like Zig. It makes the headlines and generates hype. But that went embarassingly bad for them so they had "port Bun to Rust" as a backup.by ares623
5/15/2026 at 4:39:32 AM
They should make FullstackLang. It compiles English in .md to machine code that can directly run on the specialized hardware it designs for it that you have to 3d print at runtime. Every program gets its own custom hardware. Composability and reuse be damned. Pay the token masters for every thought you haveby whattheheckheck

The term scope creep comes to mind. Programming languages do not need to grow exponentially 24/7, its okay to let it grow slowly and stay mature and secure. If Rust were too bleeding edge, the safety promises would corrode over time. I think a better use of some of those PRs is to focus on crates as proof of concepts for things that could benefit Rust if it were included either in the standard library, or just available as a crate you can use for programmer ergonomic reasons.by giancarlostoro
5/15/2026 at 5:29:46 AM
Please do fork Rust and maintain it for the LLM true believers. I’m sure the real rust team would be delighted to see fewer low-effort PRs.Given what you’ve said above it would be an easy task ‘accelerating quality and features exponentially’, so you’ll soon be able to show them (perhaps within days!), the error of their ways.
Please go do it now, we’ll wait.

That's an ambitious conclusion, and not as overly so as some may think.But I believe it is not the reason Rust adopted this policy, I think they just have a more basal and subjective dislike of AI irrespective of whatever truth you may have just cited.
by mw888
5/15/2026 at 4:19:59 AM
It doesn't really read like a Luddite policy.Rust is already well past 1.0. At best an LLM could discover a vulnerability (and the human using it can file a patch) or can help a human improve ergonomics.

LLM delusion is insufferable. If all it takes is tokens to make a significantly better in programming language in logarithmic time why hasn't anyone done it?by voxl
5/15/2026 at 5:04:51 AM
As someone who's vibecoding my own self-hosted language (via a typescript to c++ transpiler and bootstrap), I can tell you mainline commercial models like Opus 4.7 aren't quite there yet. I'm getting 10KB source files balloon into 80MB outputs for now.The main problem is that the the problem space is vast and highly interconnected, the LLM needs to reason about the entire language every time it suggest an architectural change, but it can't, so it suggests local changes that make sense to me - a language hobbyist - then runs into much more difficult problems down the road.
Maybe Mythos with a lot of (competent) human hand-holding and pre-design can do it.

The AI jackasses have been braying in this key for going on a few years now, and there hasn't been one single time any of this breathless noise has resulted in something meaningfully superior. It's time to put up or shut up. Enough bullshit talk. If you can vibeslop a better Rust (or whatever), JFDI and leave everyone behind.

Kudos to the team for this. I think it’s brave of them to stand up for their own experiences and push back against the hype train.Before you knee jerk hate on the team for being luddites, consider:
1. For a language like rust there’s too few eyes and too many mouths. Reviewing is a job, and is extremely taxing. 2. The code base needs to be highly hermetic because it’s load bearing across the global economy 3. Most changes are only relevant if they’ve followed extensive process, including community feedback.

I can’t say for certain who wrote it, and I won’t make any definitive claims - personally, I tend to think it was probably mostly written, or at least conceived, by a man - but this sort of phrase… I get a nervous twitch every time I see it, even though it’s actually quite a clever rhetorical device.
