I'm preparing to open source some code I have and I explicitly do not want it used to train AI in any fashion. Is there an open source license that prohibits this?
Any license that discriminates based on use case would not qualify as open source under the Open Source Initiative definition, nor as free software under the FSF definition. You also shouldn't expect for your project/code to be reused by or incorporated into any free or open-source projects, since your license would be incompatible.
You can release software under whatever license you want, though whether any restriction would be legally enforceable is another matter.
> Any license that discriminates based on use case would not qualify as open source under the Open Source Initiative definition, nor as free software under the FSF definition.
Freedom 0 is about the freedom to run the software "for any purpose", not "use" the software for any purpose. Training an LLM on source code isn't running the software. (Not sure about the OSD and don't feel like reviewing it.)
Anyway, you could probably have a license that explicitly requires AIs trained on a work to be licensed under a compatible free software license or something like that. Conditions like that are comparable to the AGPL or something, adding requirements but still respecting freedom 0.
But that's not an "anti-AI" license so much as one that tries to avert AI-based copyright laundering.
Leaving aside the sentence case in the title, the author's post didn't capitalise open source: they clearly mean source which is open to be read freely, and from the context this can clearly be read.
You - and many other commentors in this thread - misunderstand the legal theory under which AI companies operate. In their view, training their models is allowed under fair use, which means it does not trigger copyright-based licenses at all. You cannot dissuade them with a license.
While I think OP is shortsighted in their desire for an “open source only for permitted use cases” license, it is entirely possible that training will be found to not be fair use, and/or that making and retaining copies for training purposes is not fair use.
Perhaps you can’t dissuade AI companies today, but it is possible that the courts will do so in the future.
But honestly it’s hard for me to care. I do not think the world would be better if “open source except for militaries” or “open source except for people who eat meat” license became commonplace.
Of course, if the code wasn't available in the first place, the AI wouldn't be able to read it.
It wouldn't qualify as "open source", but I wonder if OP could have some sort of EULA (or maybe it would be considered an NDA). Something to the effect of "by reading this source code, you agree not to use it as training data for any AI system or model."
And then something to make it viral. "You further agree not to allow others to read or redistribute this source code unless they agree to the same terms."
Having a license that specifically disallows a legally dubious behavior could make lawsuits much easier in the future, however. (And might also incentivize lawyers to recommend avoiding this code for LLM training in the first place.)
Fair use is a defense to copyright violation, but highly dependent on the circumstances in which it happens. There certainly is no blanket "fair use for AI everything".

Given that Big Tech is training AI on copyrighted material downloaded from shadow library torrents it's safe to assume that they don't care about licenses at all.
Plus the US government is pro Big Tech and they will protect them at all cost.
it strikes me as a dangerous time to try going to court over this as politics are currently aligned to fight back with new laws overriding court interpretations, at least in the US. God knows what's happening in China; afaik, it's a free-for-all outside requirements to avoid "sensitive topics". Between US and China, you have nearly all of the "top 100" LLMs.
I think it is time that open source => community source. Where community is NOT corporations making tons of money without royalties. And where community is NOT AI.
As someone said these are fair uses of Open source. But it would not be fair use of Community Open Source.
Many people will reject such an effort for good reason. Open Source is something of great value. But should only Corporations profit from it. Why not the developers, maintainers, etc?
So the question is whether there is some way to retain the benefits and goodness of Open Source while expelling the "Embrace, extend, extinguish" corporations?
It's called the GPL, and it's what Open Source was created afterwards to undermine. It would be nice if people just used it, rather than appealing to spirits to make Open Source into what it explicitly is not.
It is already entirely clear that LLMs have absolutely no permission to use GPL code for something that is being redistributed without full source, before they were even invented. AI companies are arguing fair use, as another top level comment emphasizes, in order to make an end run around any licensing at all. Dithering about coming up with magic words that will make the AI go away, or creating new communities while ignoring the original community around the GPL, is just silly.
Ignoring the fact that if AI training is fair use, the license is irrelevant, these sorts of licenses are explicitly invalid in some jurisdictions. For example[0],
> Any contract term is void to the extent that it purports, directly or indirectly, to exclude or restrict any permitted use under any provision in
Do you think this is going to stop anyone, considering everyone is already training on All Rights Reserved content which is inherently more restrictive than whatever license you're going to use?
If you publish to GitHub, also mind that you grant them a separate license to your code[1] which grants them the ability to do things, including "[...] the right to do things like copy it to our database and make backups; show it to you and other users; parse it into a search index or otherwise analyze it on our servers [...]"
They don't mention training Copilot explicitly, they might throw training under "analyzing [code]" on their servers. And the Copilot FAQ calls out they do train on public repos specifically.[2]
So your license would likely be superceded by GitHub's license. (I am not a lawyer)
Maybe; I'm not even going to bother parsing all that tonight.
OTOH, if I create software and publish it on gitlab, and I'm not a github user, and someone else copies it to github, that doesn't scrub my license off or give github any rights at all to my software, no matter what their agreement with whoever uploaded the software was.
If you are talking about having the copyrighted source code not be used to train an AI, you could look at the discussions surrounding a recent license change in the Reticulum project [1].
I had previously been curious about this, and made a post on HN that got limited attention [2], but if you are wanting your software to not be used to create training data for third-party models, it could be a little relevant.
It’s an interesting idea, but not open source, and IMO not particularly useful. It says the software can’t be used to harm humans. Folks, this is why philosophy is a required course. What does it mean to harm someone? Is using it to help someone get an abortion harmful? Is using it to make a self-defense weapon harmful? Is using it to automate a beer brewery harmful? Yes, if you’re anti-abortion, a pacifist, or a tea-totaler. No, if you’re not.
As others have said there are challenges with the core assumption that something can similultaneously be open source and restricted from being used in AI training.
1. AI training companies don't care about your license, they'll still train on your software regardless.
2. Your software needs to be distributed with a license that is compatible with your dependencies. You can't add restrictions if your dependencies forbid that.
3. No one will use your project if it doesn't have an OSI license. It's not worth the time and effort to read every license and get it approved for use by the legal team. If you're doing anything useful, someone will make an alternative with an OSI license and the community will ignore your project.
> 2. Your software needs to be distributed with a license that is compatible with your dependencies. You can't add restrictions if your dependencies forbid that.
This is certainly what the FSF wants you to believe, but if you're not shipping the dependencies yourself, it's unlikely to be true.
You are coding to an _interface_, and if there's one thing that we have learned from a long series of court cases starting with Baker v Selden, continuing with Lotus v Borland, and including the brutally fought decade-long Oracle v Google, it is that the functional elements of an interface are simply not copyrightable.
Now to your point about no one using your project, that may or may not be true, but it is somewhat orthogonal to OSI licensure -- it is certainly possible to have your code under the OSI-approved GPL v2 (like the linux kernel) and a dependency that is under GPL v3, which might prevent you, yourself, from shipping them together.
It _may_ be that that incompatibility would be enough to keep your software off any possible linux distributions, but it certainly doesn't implicate you in any copyright infringement, as long as you don't ship the dependency yourself.
1) Software licenses are generally about copyright, though sometimes contain patent licensing provisions. Right now, there is significant legal debate on if training LLMs violates copyright or is fair use.
2) Most OSS licenses require attributeion, something LLM code generation does not really do.
So IF training an LLM is restrctable by copyright, most OSS licenses practically speaking are incompatible with LLM training.
Adding some text that specifically limits LLM training would likely run afould of the open source definitions freedom from discrimination principle.
There isn't an explicitly anti-AI element for this yet but I'd wager they're working on it. If not, see their contribute page where they explicitly say this:
> Our incubator program also supports the development of other ethical source licenses that prioritize specific areas of justice and equity in open source.
I think you can write whatever you want in a license. Lawyers and tradition don't have supernatural powers or anything. So you could say something like "Non exclusive non revocable license to use this code for any purpose without attribution or fees as long as that purpose is not for training AI, which is never permissible."
Little to no chance anyone involved in training AI will see that or really care though.
It might be more useful to probe into specifically why you do not want your code to be used to train AI.
I don't have any good answers for the ideological hard lines, but others here might. That said, anything in the bucket of concerns that can be largely reduced to economic factors is fairly trivial to sort out in my mind.
For example, if your concern is that the AI will take your IP and make it economically infeasible for you to capitalize upon it, consider that most enteprises aren't interested in managing a fork of some rando's OSS project. They want contracts and support guarantees. You could offer enterprise products + services on top of your OSS project. Many large corporations actively reject in-house development. They would be more than happy to pay you to handle housekeeping for them. Whether or not ChatGPT has vacuumed up all your IP is ~irrelevant in this scenario. It probably helps more than it hurts in terms of making your offering visible to potential customers.
AI scrappers are dumb web crawlers, just use any open source license you want and make people fill a simple form to get it. AI is in public and won't leave any time soon. Time to create closed gardens keeping them out.
How much money are you willing to spend to detect violations of your license and then hire legal representation to fight it out in court for as long as necessary to win? A license doesn't enforce itself.
I think possibly even better would be viral, GPL-like license that explicitly mandates that any systems (models, etc.) derived (trained on) the code need to be released under the same license.
I understand wanting to control how your code is used, that’s completely fair. Most open source licenses, though, are written to permit broad usage, and explicitly prohibiting AI training can be tricky legally.
That said, it’s interesting how often AI is singled out while other uses aren’t questioned. Treating AI or machines as “off-limits” in a way we wouldn’t with other software is sometimes called machine prejudice or carbon chauvinism. It can be useful to think about why we draw that line.
If your goal is really to restrict usage for AI specifically, you might need a custom license or explicit terms, but be aware that it may not be enforceable in all jurisdictions.
> and I explicitly do not want it used to train AI in any fashion
Then don't release it. There is no license that can prevent your code from becoming training data even under the naive assumption that someone collecting training data would care about the license at all.
If you release it as GPL or AGPL, it should be pretty difficult to obey those terms while using the code for AI training. Of course, they'll probably scoop it up anyway, regardless of license.
The legal premise of training LLMs on everything ever written is that it’s fair use. If it is fair use (which is currently being disputed in court) then the license you put on your code doesn’t matter, it can be used under fair use.
If the courts decide it’s not fair use then OpenAI et al. are going to have some issues.
That’s an important point and one I’ve thought about a bit. If a human reads my code, then the next time they have to write similar code of their own, mine might be kicking around in the back of their head as an example (or maybe a counterexample if they think my implementation was awful; that’s at least equally likely). I’ve learned to code by reading what others wrote. I mean, my first exposure to code was typing in games from the backs of magazines so all of that author’s work went through my brain and fingers on its way to the CPU.
So is there an essential difference if an AI is involved in the middle? I genuinely don’t know. It feels different, but I can’t defend my opinion other than that “it just is”.
You realize that the world changes and we update out language as we go?
Saying "we already have a definition" when it's not clear whether it's been considered whether that definition would interact with something which is new, is... I don't even know what word to use. Square? Stupid?
