It’s not possible to have a license over an ML model trained on other peoples’ works, since such models are uncopyrightable. They’re more like a phone book; a collection of facts trained by an entirely un-creative process. https://news.ycombinator.com/item?id=36691050

This hasn’t been proven in court, but it seems the most likely outcome.

And yet meta are specifying a license, implying they do hold the copyright.

They’re mistaken.

It’ll take awhile for this mistake to be reconciled in court though.

Not saying that this applies to LLMs but if you describe them as "a collection of facts [collected and] trained by an entirely un-creative process" then it begins to sound like one could argue for Database Right.

Keep working on it! A good court case and a landmark decision about this could change the landscape for the market for these models.

Llama 2 is open source-ish. Weights are freely available and can be commercially used, but only if you have less than 700m users and agree to some "don't do naughty things" terms.

If the JSON license isn't considered open, due to requiring that "The Software shall be used for Good, not Evil.", then I don't see how tacking an additional financial threshold onto it makes it more open. I don't think meta even released the training dataset, so you cant even replicate it (should you have the funds to do so).

There are other LLMs that don't have such restrictions, and publish their training data.

There is no open source-ish. It either protects the fundamental freedoms or it...doesn't.

Sure there is, BSD is bad because xyz, GPL is bad because zyx. That said Llama restrictions are rather harsh and you are not allowed to improve other models with it. So no freedom there just some ok beer.

Open source is both a colloquial term for available/modifiable/distributable code (like Llama2), and a strict OSI-approved list of licenses. I'd say opensource-ish is a great fit here.

"open source-ish" sounds like the perfect way to massively profitable future litigations.

Also "don't do naughty things", is there a chart for that? How is that defined, is it part of the non-existing license?

What do you mean? https://github.com/facebookresearch/llama/blob/main/LICENSE

Nope. It's limited by 700m monthly-active users at the time Llama2 was released, a weird catch clause for a handful of Meta competitor companies. The license doesn't satisfy OSS requirements, but it is quite reasonable.

From memory llama 2 license does allow tuned models with suitable credit & license inclusion. The restricted using it to train other models though (a bit like people use gpt4 to generate question/answer pairs to train their models)
