TLDR: It’s compatible with other copy-left licenses like GPLv3. However, it’s available in multiple languages, which technically makes it more applicable.
I started using it for my own project. If you want a practical example: https://github.com/TimoKats/emmer


Is there a license that permits free use by humans but not LLMs?
Not a lawyer, but I don’t think so. there are licenses that extend existing licenses with that clause, like BSD NON-AI
That would be CC BY-NC-SA.
Creative Commons,
Attribution,
Non-Commercial,
Share Alike.
Meaning you need to attribute to the original author, can only use it for non-commercial purposes, and must share alike (i.e., your derivation must have the same attribution rules).
Imho there should be a “Commercial only for worker co-ops” option.
Maybe we also need to consider internet content and written books by default as something not allowed to be scraped by AI. Only that which is in public domain may be scraped.
Practically all the free software licenses require some form of attribution. CC licenses are not really suited for code. I would say the GPL is way more applicable here.
It’s not like these licenses require approval by any regulatory board. Remember you can write “all rights reserved” on any of your copyrightable work and extend no license to anyone whatsoever, or you can voluntarily release your work into the public domain and relinquish your copyright entirely, or anything in between.
Sadly the prevailing opinion seems to be that the most strict option (all rights reserved) doesn’t protect you from LLMs.
At that point, no license will help you, because they’re outright ignoring the law.
Yep. Either they’re ignoring the law and face no consequences or case law settles that scraping copyrighted content for LLM models is fine, in which case again, it doesn’t matter.
I’m afraid that might be correct :( perhaps closing off software to the public will be the only way to prevent it from getting stolen
