We need a clearer framework for AI-assisted contributions to open source

As both developers and stewards of significant open source projects, we’re watching AI coding tools create a new problem for open source maintainers.

AI assistants like GitHub Copilot, Cursor, Codex, and Claude can now generate hundreds of lines of code in minutes. This is genuinely useful; but it has an unintended consequence: reviewing machine generated code is very costly.

The core issue: AI tools have made code generation cheap, but they haven’t made code review cheap. Every incomplete PR consumes maintainer attention that could go toward ready-to-merge contributions.

At Discourse, we’re already seeing this accelerating across our contributor community. In the next year, every engineer maintaining open source projects will face the same challenge.

We need a clearer framework for AI-assisted contributions that acknowledges the reality of limited maintainer time.

A binary system works extremely well here. On one side there are prototypes that simply demonstrate an idea. On the other side there are ready for review PRs that meet a project’s contribution guidelines and are ready for human review.

The lack of proper labeling and rules is destructive to the software ecosystem

The new tooling is making it trivial to create a change set and lob it over the fence. It can introduce a perverse system where project maintainers spend disproportionate effort reviewing lopsided AI generated code that took seconds for contributors to create and now will take many hours to review.

This can be frustrating, time consuming and demotivating. On one side there is a contributor who spent a few minutes fiddling with AI prompts, on the other side you have an engineer that needs to spend many hours or even days deciphering alien intelligence.

This is not sustainable and is extremely destructive.

The prototype

AI coding agents such as Claude Code, Codex, Cursor CLI and more have unlocked the ability to ship a “new kind” of change set, the prototype.

The prototype is a live demo. It does not meet a project’s coding standards. It is not code you vouch for or guarantee is good. It lacks tests, may contain security issues and most likely would introduce an enormous amount of technical debt if merged as is.

That said it is a living demo that can help make an idea feel more real. It is also enormously fun.

Think of it as a delightful movie set.

    This is a problem everywhere now, and not just in code. It now takes zero effort to produce something, whether code or a work plan or “deep research” and then lob it over the fence, expecting people to review and act upon it.

    It’s an extension of the asymmetric bullshit principle IMO, and I think now all workplaces / projects need norms about this.

      This problem statement was actually where the idea for Proof of Work (aka mining) in bitcoin came from. It evolved out of the idea of requiring a computational proof of work for sending an email via cypherpunk remailers as a way of fighting spam. The idea being only a legitimate or determined sender would put in the "proof of work" to use the remailer.

      I wonder how it would look if open source projects required $5 to submit a PR or ticket and then paid out a bounty to the successful or at least reasonable PRs. Essentially a "paid proof of legitimacy".

        The parallel between PoW and barriers to entry many communities (be it Wikipedia editors or open-source contributors) use to sustain themselves seems apt.

        Unfortunately, there is no community equivalent of PoS—the only alternative is introducing different barriers, like ID verification, payment, in-person interviews, private invite system, etc., which often conflict with the nature of anonymous volunteer communities.

        Such communities are perhaps one of the greatest things the Web has given us, and it is sad to see them struggle.

        (I can imagine LLM operators jumping on the opportunity to sell some of these new barriers, to profit from selling both the problematic product and a product to work around those problems.)

          That is their business model. Use AI to create posts in LinkedIn, mails in a corporate environment, etc. And then use AI to summarize all that text.

          AI creates a problem and then offers a solution.

          My current approach is to look at new sources lie The Guardian, Le Monde, AP news, etc. I know that they put the work, sadly places like Reddit and such are just becoming forums that discuss garbage news with bot comments. (I could use AI to identify non-bot comments and news sources, but it does not really work even if it says that it does, and I should not have to do that in the first place either).

          The community equivalent of Proof of Stake is reputation. You can't do anything until you've shown up for awhile and contributed in small ways, you gradually gain the ability to contribute in bigger ways, and if you are discovered to be malicious or corrupt or toxic, then your rights are revoked. The people who've gained this trust are presumably motivated to maintain it (although there's always the risk they sell their account/identity/soul for healthcare and do some damage before they're found out).

      But why should this expectation be honored? If someone spends close to zero effort generating a piece of code and lobs it over the fence to me, why would I even look at it? Particularly if it doesn't even meet the requirements for a pull request (which is what it seems like the article is talking about)?

      • By hippo22 2025-10-295:051 reply

        Because that's the definition of collaboration? Prior to the invention of LLMs, one could generally assume requests for collaboration were somewhat sincere due to the time investment involved. Now we need a new paradigm for collaboration.

            The problem is that the sheer volume of low-quality AI PRs is overwhelming. Just the time it takes determining whether you should pay attention to a PR or not can add up when there are a lot of plausible-looking, but actually low-quality and untested, pull requests to your project.

            But if you stop looking at PRs entirely, you eliminate the ability for new contributors to join a project or make changes that improve the project. This is where the conflict comes from.

            • By saghm 2025-10-297:44

              Since the bar to opening a PR has gotten lower, there's an argument that the bar for closing it might need to be lowered as well. I think right now, we consider the review effort to be asymmetric in part because it's natural to want to give the benefit of the doubt to PR authors rather than making a snap judgement from only a looking briefly at something; the current system seems to place a higher value on not accidentally closing a potentially useful but poorly presented PR than not accidentally wasting time on one that superficially appears like it might be good but isn't. I have to wonder if the best we can do is to just be more willing to close PRs when reviewers aren't sufficiently convinced of the quality after a shorter inspection regardless of whether we're 100% certain about whether that judgment is perfect. If "false positive" PRs that seem reasonable but turn out not to be are better at appearing superficially good, the best option seems like it might just be to be willing to throw out more "false negatives" that would be useful but aren't sufficiently able to distinguish themselves from the ones that aren't.

              After a minute (or whatever length of time makes sense for the project), decide whether you're not fully confident that the PR is worth your time to continue reviewing, with the default answer being "no" if you're on the fence. Unless it's a yes, you got a bad vibe; close it and move on. Getting a PR merged will require more effort in making the case that there's value in keeping it open, which restores some of the balance that's been lost in the effort having been pushed to the review side.

              PR authors blow now need to spend energy and effort to make their PR appear worthwhile for consideration. AI PRs will have the effect of shifting the burden of effort to the PR authors (the real ones).

              No more drive-by PRs.

      Where is the problem? If I don't have the time to review a PR, I simply reject it. Or if I am flooded in PRs, I only take those from people from which I know that their PRs are of high quality. In other words: your assumption "expecting people to review and act upon it" is wrong.

      Even though I would bet that for the kind of code that I voluntarily write in my free time, using an LLM to generate lots of code is much less helpful because I use such private projects to try out novel things that are typically not "digested stuff from the internet".

      So, the central problem that I rather see is the license uncertainties for AI-generated code.

It produced an amazingly accurate thought train and found my issue, which was not what I was expecting at all.

      I've been skeptical about LLMs being able to replace humans in their current state (which has gotten marginally better in the last 18 months), but let us not forget that GPT-3.5 (the first truly useful LLM) was only 3 years ago. We aren't even 10 years out from the initial papers about GPTs.

      • By dragontamer 2025-10-2815:401 reply

        > was only 3 years ago

        That's one way of looking at it.

        Another way to look at it is GPT3.5 was $600,000,000,000 ago.

        Today's AIs are better, but are they $600B better? Does it feel like that investment was sound? And if not, how much slower will future investments be?

        • By jermaustin1 2025-10-2816:041 reply

          Another way to look at $600B of improvement was whether or not they used the $600B to improve it.

          This just smells like classic VC churn and burn. You are given it and have to spend it. And most of that money wasn't actually money, it was free infrastructure. Who knows the actual "cost" of the investments, but my uneducated brain (while trying to make a point) would say it is 20% of the stated value of the investments. And maybe GPT-5 + the other features OpenAI has enabled are $100B better.

        And yet, we're clearly way into the period of diminishing returns.

        I'm sure there's still some improvements that can be made to the current LLMs, but most of those improvements are not in making the models actually better at getting the things they generate right.

        If we want more significant improvements in what generative AI can do, we're going to need new breakthroughs in theory or technique, and that's not going to come by simply iterating on the transformers paper or throwing more compute at it. Breakthroughs, almost by definition, aren't predictable, either in when or whether they will come.

      • By troupo 2025-10-2910:32

        Why are you assuming exponential or even linear growth/improvement?

        E.g. OpenAI went from "AGI has been achieved internally" to lying with graphs (where they cut off graphs at 50% or 70% to present minor improvements as breakthroughs).

        The growth can easily be logarithmic

      I feel like we need a different programming paradigm that's more suited to LLM's strengths; that enables a new kind of application. IE, think of an application that's more analog with higher tolerances of different kinds of user inputs.

      A different way to say it. Imagine if programming a computer was more like training a child or a teenager to perform a task that requires a lot of human interaction; and that interaction requires presenting data / making drawings.

      When people talk about the “AI bubble popping” this is what they mean. It is clear that AI will remain useful, but the “singularity is nigh” hype is faltering and the company valuations based on perpetual exponential improvement are just not realistic. Worse, the marginal improvements are coming at ever higher resource requirements with each generation, which puts a soft cap on how good an AI can be and still be economical to run.

        I won't get into whether the improvements we're seeing are marginal or not, but whether or not that's the case, these examples clearly show you can get improved performance with decreasing resource cost as techniques advance.

          But that's exactly the problem!

          Right now, AI performs poorly enough that only a small fraction of users is willing to pay money for it, and (despite tech companies constantly shoving it in everyone's face) a large portion of the user base doesn't even want to adopt it for free.

          You can't spend hundreds of billions of dollars on marginal improvements in the hope that it'll hopefully eventually become good enough for widespread adoption. Nobody is going to give OpenAI a trillion dollars to grow their user base 50x over the next 15 years. They are going to need to show significant improvements - and soon, or the bubble will pop.

      I was extremely skeptical at the beginning, and therefore critical of what was possible as my default stance. Despite all that, the latest iterations of cli agents which attach to LSPs and scan codebase context have been surprising me in a positive direction. I've given them tasks that require understanding the project structure and they've been able to do so. Therefore, for me my trajectory has been from skeptic to big proponent of the use, of course with all the caveats that at the end of the day, it is my code which will be pushed to prod. So I never went through the trough of disillusionment, but am arriving at productivity and find it great.

        There are 3 parts of the process the AI agent can't do - the start, the middle and the end :) No, really, they need humans to identify tasks worth working on, then guide the model during development and providing iterative feedback, and in the end we incur the outcomes, good or bad. We are the consequence sinks, we take the costs and risks on ourselves. LLMs have no accountability.

    I really like the way Discourse uses "levels" to slowly open up features as new people interact with the community, and I wonder if GitHub could build in a way of allowing people to only be able to open PRs after a certain amount of interaction, too (for example, you can only raise a large PR if you have spent enough time raising small PRs).

    This could of course be abused and/or lead to unintended restrictions (e.g. a small change in lots of places), but that's also true of Discourse and it seems to work pretty well regardless.

    • By warmwaffles 2025-10-2814:04

      Mailing lists are used as a filter to raise the barrier to entry to prevent people from contributing code that they have no intention of maintaining and leaving that to the project owners. Github for better or worse has made the barrier to entry much much lower and significantly easier for people to propose changes and then disappear.
