Can you copyright AI generative works?

Google's AI response to this:

it's not entirely correct that AI-generated content cannot receive copyright protection in the US; rather, purely AI-generated works without sufficient human creative input are not eligible for copyright, but human-created works that use AI as a tool and incorporate significant human authorship can receive protection. The U.S. Copyright Office maintains that copyright requires a human author, meaning a simple prompt isn't enough to claim authorship of AI output, but significant human editing, selection, and arrangement of AI-generated elements may qualify the overall work for copyright protection.

This is a good response from congress.gov

May Humans Copyright Works That They Create Using AI?

Assuming that copyrightable works require a human author, works created by humans with the assistance of generative AI might be entitled to copyright protection depending on the nature of human involvement in the creative process. As discussed below, the Copyright Office has sought to delineate what authors must do to satisfy the human-authorship requirement when using generative AI.

In March 2023, the Copyright Office released Copyright Registration Guidance regarding "works containing material generated by [AI]" (the AI Guidance). Granting that human authors may use AI in the creative process, the AI Guidance states that "what matters is the extent to which the human had creative control over the work's expression." Thus, the AI Guidance states, when AI "determines the expressive elements of its output, the generated material is not the product of human authorship." On the other hand, works containing AI-generated material may be copyrighted under some circumstances, such as "sufficiently creative" human arrangements or modifications of AI-generated material or works that combine AI-generated and human-authored material. The AI Guidance states that authors may claim copyright protection only "for their own contributions" to such works, and they must identify and disclaim AI-generated parts of the works when applying to register their copyright.
