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.
If training AI is a copyright exemption, and it is likely to be the case, then the license is irrelevant.
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.
Laws cannot be changed retroactively. So if AI training is a copyright extension that can only happen starting sometime next year. So the consequences of these companies' choices are already set in stone, even if they're not known yet.
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?
Um, no. Copyright puts specific restrictions on what you can do with work. Those restrictions are described by certain words. The question is whether the existing restrictions cover training AI. That's a matter of interpretation, but once an interpretation is accepted, it is understood as what copyright always meant.
Training AI is probably not a copyright violation because it never was one to begin with.
Depending on how the courts weigh in on the role of fair use in AI training, it's possible that a "copyleft for AI" clause would end up either redundant with the existing GPL, or legally void. It would be crazy complicated to enforce if it does hold water though.
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.
I disagree. They said open source, so I’ll take them at their word that they mean open source. If they meant otherwise, they should’ve said that instead.
This is a highly nitpicky topic where terms have important meanings. If we toss that out, it becomes impossible to discuss it.
I've linked elsewhere to the Hippocratic License, which freely refers to itself as open source while specifically being built around refusing licensing based on ethical considerations. OSI don't own the term open source, and the simple and plain meaning of the term is clear to see. Otherwise, we wouldn't consider GPL software to be open source, because it attaches conditions on usage. That even applies to non-copyleft licenses like MIT which demand author attribution. The term open source is best read literally unless someone says "I want an OSI approved license".
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.
Your first link (Canada/BC) offers guidelines for BC government usage of open source software. In this type of situation, the OSI's list of approved licenses (and OSD in general) is very helpful, since it avoids massive duplicative legal overhead of evaluating software licenses. But in my opinion, that has little bearing on whether or not people should strictly follow this definition in an international public forum.
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.
that would be “source available” software, and it’s not a random initiative
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)
> 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.
Indeed, and it can also be free software and under a copyleft license (GPL AGPL etc) and not accept contributions. Otherwise, every project that shut down or was just a one off gist/blog post to begin with couldn't be called open source either!
argh I will re-edit my comment…sorta covered by the “disagreement” bit, and I disagree on this point (it’s not open to me if you don’t openly accept contributions), but you are right
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?
> PERSONALLY, I think if you don’t welcome outside contributions, it isn’t open source
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.
it’s not made up (well all language is made up but I digress), you’re just being flagrantly ignorant of the terms you’re using and their history. you can easily go read up on open source vs source available and the history of the terms/licenses
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
The OSI definition of open-source software is recognized by several governments worldwide as definitive and legally binding. What you're describing is source available and that's a very different thing.
They applied for a trademark and were rejected due to the term being too generic/descriptive. It has nothing to do with whether they hold IP.
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.
I didn't say a trademark isn't a form of IP. I said their application for a trademark was rejected due to "open source" being too generic/descriptive, not due to the reason you directly asserted above ("They don't hold the IP, I don't really see any way they could be granted a trademark on it").
The didn't redefine the words, they defined them. Anyone using them for anything other than the purposes they were defined to cover is a dishonest parasite who is intending to trade on the goodwill of the people who adhere to OSI's guidelines. "Open Source," capitalized or not, was not a common phrase before they introduced it. I don't care if somebody in 1965 said "I decided I'm going to be open, and share the source code!" Somebody sitting right next to him probably said "I decided I'm going to be open, and tell people that I will never share the source code."
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.
As a personal anecdote, while I’ve heard smart people say they were using “open source” way back when, I had personally never heard it used in any way before starting to used Linux and the BSDs in the late 90s, when OSI came along and people started discussing it in that context.
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.
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.
> 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 ...
Open source except for people who have downvoted any of my comments.
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.
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."
My understanding is that you can have such an agreement (basically a kind of NDA) -- but if courts ruled that AI training is fair use, it could never be a copyright violation, only a violation of that contract. Contract violations can only receive economy damages, not the massive statutory penalties that copyright does.
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.
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
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)
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.
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.
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.
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?
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.
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.
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.
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.
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.
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.
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?
> 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
We even have such term already. It's source-available. Nothing necessarily wrong or bad about it. It only requires people to be honest with themselves and don't call code open if it's not.
Rather, the definition as it is now, and has been for some time, addresses the same old difficulties and distractions that rear their heads again and again wearing slightly different masks.
> 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.
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.

Open Source means OSI-approved license in the software context. Some government examples of this being explicitly mentioned:

The OSI definition of open-source software is recognized by several governments worldwide as definitive and legally binding. What you're describing is source available and that's a very different thing.

Anyone using them for anything other than the purposes they were defined to cover is a dishonest parasite who is intending to trade on the goodwill of the people who adhere to OSI's guidelines. "Open Source," capitalized or not, was not a common phrase before they introduced it. I don't care if somebody in 1965 said "I decided I'm going to be open, and share the source code!" Somebody sitting right next to him probably said "I decided I'm going to be open, and tell people that I will never share the source code."
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.
As a personal anecdote, while I’ve heard smart people say they were using “open source” way back when, I had personally never heard it used in any way before starting to used Linux and the BSDs in the late 90s, when OSI came along and people started discussing it in that context.
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.
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.
The problem are "viral" licences. Must the code generated by an AI trained with GPL code be released with a GPL licence?
Also, can an AI be trained with the leaked source of Windows(R)(C)(TM)?
> 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 ...
Open source except for people who have downvoted any of my comments.
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.
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."
My understanding is that you can have such an agreement (basically a kind of NDA) -- but if courts ruled that AI training is fair use, it could never be a copyright violation, only a violation of that contract. Contract violations can only receive economy damages, not the massive statutory penalties that copyright does.
People think that code is loaded into a model, like a massive available array of "copy+paste" snippets.
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.
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.
Quoting a previous comment of mine:
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],

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)

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.
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.
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.
The goal is to prevent AI from devaluing SWE work.
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?
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.
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.
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.
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.
Zero chance this gets respected but worth doing nonetheless.
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.
Use an erotic text to trigger pretraining filters.
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.
Presumably the author is working on the basis that it is not fair use and wants to license accordingly.
Why is it ok for humans to read your code but not AIs?
If you don't want AIs to train on it you should not open source it.
I think some variation of the Hippocratic License will probably work for you. See:
https://firstdonoharm.dev/
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.
If it’s open source but with an extra restriction then it’s not Open Source:
https://opensource.org/osd
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?
> 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.
Rather, the definition as it is now, and has been for some time, addresses the same old difficulties and distractions that rear their heads again and again wearing slightly different masks.
> 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.
