# ANSWER OF DEFENDANT SUNO, INC. TO COMPLAINT

## Retrieval answer

Suno filed its answer on October 20, 2026, in a copyright case brought in the U.S.

Suno filed its answer on October 20, 2026, in a copyright case brought in the U.S. District Court for the District of Massachusetts by UMG Recording entities, Sony Music Entertainment entities, and other record-label plaintiffs. The complaint was filed on September 18, 2026.

In the filing, Suno admits that it obtained audio data from YouTube for use as training data, including through YT-DLP. It also says it has not publicly disclosed the contents of its training data and describes that information as highly confidential. Suno admits it has not deleted all recordings used to train its models, stating that retention is consistent with plaintiffs' pre-litigation demand to preserve training datasets.

Suno also admits releasing v6, v6-wild, and v6-mini on September 9, 2026. It says v6 was trained on licensed partner content, community interactions including creations and preference signals, and accumulated team learnings. The company asserts fair use and other defenses, seeks dismissal with prejudice, and requests attorneys' fees.

The answer records Suno's litigation positions and admissions; it does not establish whether the alleged training or outputs infringe copyright, whether fair use applies, or the eventual outcome of the case.
