Minor correction, but in the US it's not anything that's 100% by AI, it's LLM output itself is not copyrightable. Human elements injected into LLM output are.

Raw LLM output lacks human authorship, and it was ruled cannot be registered for copyright protection. Raw LLM output is automatically public domain (which is also why its silly for Anthropic to be in such a tizzy about China using Claude's output, Claude's output is public domain).

Only the parts of a work that are human authored can be registered for copyright. If a work was created with AI assistance, the parts that were purely AI generated cannot be registered.

The US copyright office also ruled that prompt engineering does not count as human authorship.

So all those people using Suno to generate AI slop music and flooding the streaming services, their output is almost certainly public domain.

>(which is also why its silly for Anthropic to be in such a tizzy about China using Claude's output, Claude's output is public domain).

I don't see how it's any more weird than reddit/stackoverflow/linkedin trying to clamp down on AI scrapers, even though they don't own the copyright to the UGC that they're preventing the bots from accessing.
