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?
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.
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
