"They don't need copyright ownership of the AI output to make part of the conditions for using their software running on their servers (API access) an agreement not to use it training a competing AI model."
You are missing the point.
Copyright law and the copyright act, not general contract law, governs whether a contract provision relating to AI output can be enforced by Anthropic, and since copyright law says Anthropic has no copyright in the output, Anthropic will not win in court.
It's not different than if Anthropic included a provision saying you won't print out the text of Moby Dick. Anthropic doesn't own copyright on Moby Dick and can't enforce a contract provision related to it.
Like I said I can be convinced I'm wrong based on a legal analysis from a neutral party but you seem to be arguing from first principles.
No, I am disagreeing with the point, because it's completely wrong.
> Copyright law and the copyright act, not general contract law, governs whether a contract provision relating to AI output can be enforced by Anthropic
No, it doesn't. There is no provision of copyright law that limits terms of contracts covering AI outputs.

This is true, but undermines your point.
> Anthropic doesn't own copyright on Moby Dick and can't enforce a contract provision related to it.
Actually, providing services that allow you to produce output can enforce provisions prohibiting reproducing works they don't own the copyright to (and frequently do adopt and enforce rules prohibiting this for things other people own the copyright to).
> Like I said I can be convinced I'm wrong based on a legal analysis from a neutral party but you seem to be arguing from first principles.
You seem to be arguing from first principles that are entirely unrelated to the actual principles, statutory content of, or case law of contracts or copyrights, and I have no idea where they come from, but, sure, believe whatever you want, it doesn't cost me anything.
"In jurisdictions that follow the Second Circuit's more restrictive approach, plaintiffs may be limited to bringing copyright infringement claims when the scope of license terms or other contractual restrictions on the use of works has been exceeded. Plaintiffs who do not own or control the copyright interest in the licensed work, however, will not be able to bring such claims and may be left without an enforcement mechanism under traditional contracting approaches."
>>There is no provision of copyright law that limits terms of contracts covering AI outputs.
This isn't how legal reasoning works in a common law system... to discover the answer you usually find the most similar case to the current fact pattern and then compare it to the current issue.
If you are aware of such a case, even colluqually, point me in the right direction. It might be hard to analogize to another cases though, because Anthropic doesn't have a license for most of the training materials that made their model. I've also read you can't contract around a fair use defense.
If I'm wrong it isn't very helpful to shout "na uh" without further explanation. Give me some search engine keywords and I'll look up whatever you point me towards.
