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.
