Key Takeaways
You can release software under whatever license you want, though whether any restriction would be legally enforceable is another matter.
If it is not then the trained AI is a derivative work, which the license should allow as long as it is publishable under the same license to be considered open source or free software.
In any case, I don't think an anti-AI clause would serve a meaningful purpose on open source software. You can however make your own "source available" license that explicitly prevents its use on AI training, and I am sure that some of them exist, but I don't think it will do much good, as it is likely to be unenforceable (because of copyright exemptions) and will make it incompatible with many things open source.
The GPL requires that all materials to reproduce any derivative work be made available at cost (and all models can reproduce linux kernel GPL data structures, including the private parts, character-by-character). So do I get access to OpenAI's full training data?
Or do I get to make and publish Mickey Mouse cartoons by training an AI on Disney movies then publishing the model output. Hell, I could even make better versions of old Disney movies, competing with half of Disney's current projects!
It seems to me one of these must be true. So which is it?
Training AI is probably not a copyright violation because it never was one to begin with.
https://www.dw.com/en/openai-loses-song-lyrics-copyright-cas...
Note that OpenAI has now testified that they indeed used copyrighted works to train their models. The outcome of the case is that both training AI models using copyrighted work and providing AI model outputs that are derivative of some copyrighted work are copyright violations, and would mean model owners have to respect licenses (ie. compensating the authors)
The case can still be appealed, so it is not final. On the other hand, if I'm reading WTO copyright treaty rules correctly, this ruling applies in the US.
In the US things seem to be going in a similar direction: https://www.publishersweekly.com/pw/by-topic/digital/copyrig...
Seems to me this can still easily go the way the authors want it to in the US. And in theory, it doesn't even have to, OpenAI lost. Yes, it can be fought on appeal, but I've always heard that winning an appeal after losing a case is 10x harder than winning that case in the first place. And we'll know in early January if OpenAI fights it at all, so it's not like they have a lot of time left.
there is disagreement on exactly what “open source” means, but generally clear boundaries between open source and source available software in licensing and spirit of the given project. e.g. MIT and Apache 2.0 are open source, BSL is source available. if you don’t welcome outside contributions, it isn’t open source
That isn't true. Open source refers to the ability to make use of the source code if you wish, not the ability to send pull requests. SQLite is open source (public domain even!), but does not accept contributions from outside.
Arguably it is, in the sense that they didn't actually invent the term; there are many documented pre-OSI uses (including by high-profile folks like Bill Joy) saying "open source" to just mean "source available". And OSI's attempt to trademark the term was rejected.
> if you don’t welcome outside contributions, it isn’t open source
That isn't even part of the OSI's definition, so what are you basing this on?
It's not a question of belief. Maybe words don't mean anything anymore, but certainly legal contracts and licenses do. "Open Source" is a class of licenses approved by the OSI. There are no spirits involved.
As for the list, see [0].
That list doesn't appear to be "legally binding" in a general sense; to me, the way you worded that implies "there is a law saying OSD is the definition of open source in this country" which is very far from the case.
Instead that list appears to be specific cases/situations e.g. how some US states evaluate bids from vendors, or how specific government organizations release software. And many things on that list are just casual references to the OSI/OSD but not laws at all.
An attempt to trademark "open source hardware" was also rejected for the exact same reason. https://opensource.com/law/13/5/os-hardware-trademark-reject...
Because prefixing something with the word "Open" to imply that it would be transparent (in any context) wasn't even common before the term "Open Source" was invented. When people do that, they're hoping that the goodwill that Open Source has generated will be transferred to them, and they are judged on that basis. "Open" generally had a slightly different meaning: honest.
> A random "initiative"
And when you play stupid, nobody respects your argument. It's self-defeating.
I can’t say others weren’t using it before then. I can say say that I first heard of Open Source after I’d heard of Free Software.
Like, if people had collectively used the term 23 times through 1996, then 837,000 times in 1997 or whenever OSI popularized it, I’m fully onboard with saying it’s their term.
- Canada/British Columbia: https://www2.gov.bc.ca/assets/gov/government/services-for-go... - European Union (this applies to all EU member states): https://eur-lex.europa.eu/eli/reg/2024/2847/oj/eng - search for "Free and open-source software is understood" in the text - Germany (the EU definition already applies here, but for good measure): https://www.bsi.bund.de/DE/Themen/Verbraucherinnen-und-Verbr...
Words have meaning!
As far as I can see, your second link (applies to all EU member states) makes no mention of the OSI whatsoever, and uses a definition that is far briefer and less specific than the OSD.
I cannot evaluate the third link (Germany) as I don't speak German and automatic translation may introduce subtle changes.
This is a highly nitpicky topic where terms have important meanings. If we toss that out, it becomes impossible to discuss it.
The GPL places no restrictions on how you can run the software. All meaningful licenses place restrictions — or, conversely, limit the permissions they grant — on how the code can be used, distributed, integrated with other projects, etc.
But I disagree that the meaning of Open Source is malleable. As others here said, if we want to make a new definition, we should make a new term. In my opinion, in this case, we have. It’s Source Available, which is basically “look, but don’t touch”. And as with other brightly colored things in nature, it’s generally best to avoid it.
> the author's post didn't capitalise open source: they clearly mean
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?
The word you're looking for is "correct". The definition doesn't change just because circumstances do. If you want a term to refer to "open source unless it's for AI use", then coin one, don't misuse an existing term to mean something it doesn't.
> If you want a term to refer to "open source unless it's for AI use", then coin one
So it's a bit ironic to argue that terms cannot be redefined, when that's already what happened with "open source" and what got us here in the first place. If OSI had chosen a novel term (e.g. "Sourceware" was one option they considered), they would have been able to trademark it and avoid this entire multi-decade-long argument.
Absolutely does, that's exactly something that languages do.
If the courts decide it’s not fair use then OpenAI et al. are going to have some issues.
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.
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”.
Scrapers gobble everything up. Good, bad, memorable, non-memorable. Doesn't matter. I don't know, maybe one day I'll make a small piece of code that changes how an AI behaves (profoundly, by being in the training data, not superficially when used in the prompt). However, that hasn't happened yet. I also think it's unlikely to happen.
I know this isn't what you were going for, but it's good enough for this discussion to estabilish a critical difference. I don't even have to touch consciousness or anything like that to argue within those lines.
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.
Also, can an AI be trained with the leaked source of Windows(R)(C)(TM)?
I think you mean to ask the question "what are the consequences of such extreme and gross violations of copyright"
Because they've already done it. The question is now only ... what is the punishment, if any? The GPL requires that all materials used to produce a derivative work that is published, made available, performed, etc. is made available at cost.
Does anyone who has a patch in the Linux kernel and can get ChatGPT to reproduce their patch (ie. every linux kernel contributor) get access to all of OpenAIs training materials? Ditto for Anthropic, Alphabet, ...
As people keep pointing out when defending copyright here: these AI training companies consciously chose to include that data, at the cost of respecting the "contract" that is the license.
I agree with you though. I get sad when I see people abuse the Commons that everyone contributes to, and I understand that some people want to stop contributing to the Commons when they see that. I just disagree - we benefit more from a flourishing Commons, even if there are free loaders, even if there are exploiters etc.
It wouldn't qualify as "open source", but I wonder if OP could have some sort of EULA. 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."
It's understandable that people think this, but it is incorrect.
As an aside, Anthropic's training was ruled fair use, except the books they pirated.
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.

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 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.
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)
[1] https://docs.github.com/en/site-policy/github-terms/github-t...
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.
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.
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.
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
> [...]
> Division 8 (computational data analysis)
They’d happily vacuum it up knowing that they have a much larger litigation budget than you do.
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.
That being said, here's a repo of popular licenses that have been modified to restrict such uses: https://github.com/non-ai-licenses/non-ai-licenses
IANAL, so I can't speak to how effective or enforceable any of those are.
2) Most OSS licenses require attributeion, something LLM code generation does 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.
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.
And a license will not even help you keeping them accountable.
These people are untouchable, they go on Tucker Carlson’s show and are surprised they get asked about their dead whistleblower’s case, completely fumble their response, and still nothing happens to them.
Little to no chance anyone involved in training AI will see that or really care though.
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.
