| Challenge: | Large language models are trained on vast datasets that include copyrighted material or content with usage restrictions. |
| Approach: | They propose a "copyright takedown" method that provides certified copyright take down . they use a combination of inference-time and rewriting techniques to transform potentially infringing segments . |
| Outcome: | The proposed method reduces infringement risk, preserves utility, and accommodates different levels of enforcement stringency with adaptive abstention. |
