Suno moves to keep size of its AI training data sealed in UMG and Sony's copyright case, citing 'competitive harm'

▤ Summary

Suno is asking a federal court to keep the exact size of its AI music training dataset confidential in the copyright case brought by Universal Music Group and Sony Music Entertainment. The company argues that revealing the figure would expose competitively sensitive information and help rivals benchmark their own models. The labels already allege that Suno trained on millions of copyrighted recordings and are seeking to add more than 61,000 works to the lawsuit. Suno is also preparing to oppose the labels’ motion to amend the complaint, while the broader litigation remains active through 2027.
