AI to Human Ratio for Copyright Standards
Below is the “Artistic Contribution Standard” (ACS) ratio for AI-influenced works submitted for copyright with the U.S. Library of Congress.
The ACS is designed to standardize any works submitted for copyright or to clearly indicate—without ambiguity—on your website, business, or personal documents the level of AI and human influence in your creations.
