Thanks for the links to the Gentoo discussion and policy!

IMHO the discussion and the resulting policy is interesting and maybe
something similar would be appropriate for FFmpeg.

I also became aware of LLVM policy:

  https://llvm.org/docs/DeveloperPolicy.html#ai-generated-contributions

But I must say I do not like it as much. To cite the most critical part:

    As such, the LLVM policy is that contributors are permitted to use
    artificial intelligence tools to produce contributions, provided that
    they have the right to license that code under the project license.
    Contributions found to violate this policy will be removed just like
    any other offending contribution.

For "AI" (in the LLM sense) I think it's usually not at all easy to
say if one has the right to license the code given it's trained on
a huge corpus of copyrighted and particularly licensed code.

Anyway they agree on license/copyright concern I raised. As does Gentoo.

And the LLVM policy also comes to a similar conclusions, as does Gentoo,
regarding waste of project resources:

    We encourage contributors to review all generated code before sending
    it for review to verify its correctness and to understand it so that
    they can answer questions during code review. Reviewing and maintaining
    generated code that the original contributor does not understand is not
    a good use of limited project resources.


If anyone has more examples at hand, it would probably be interesting to
know and take a look.

Best regards,
  Alexander
