You can release software under whatever license you want, though whether any restriction would be legally enforceable is another matter.
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.
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.
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.
edit: PERSONALLY, I think if you don’t welcome outside contributions, it isn’t open source; see others’ responses for disagreement on this (it’s not a part of the standard definition)
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.
it’s also fine by me if you want to have your own definition; see other comments, I don’t personally 100% agree with OSI’s definition myself
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?
edited my comment —- that is my personal belief/definition
I did mention there’s disagreement —- I haven’t read up on the history and whatnot myself in a while. will have to do some re-reading :)
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 completely 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.
- 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
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.
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.
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.
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.
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.
And if they don't have to respect licenses, then if I run old Disney movies through a matrix and publish the results (let's say the identity matrix)? How about 3 matrices with some nonlinearities? Where is the limit?
Since copyright law cannot be retroactively changed, any update congress makes to copyright wouldn't affect the outcome for at least a year ...
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."
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.
[1]: https://github.com/markqvist/Reticulum?tab=License-1-ov-file...
Plus the US government is pro Big Tech and they will protect them at all cost.
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.
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

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.
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 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.
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.
Little to no chance anyone involved in training AI will see that or really care though.
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)
