# Universal and Sony Sue Suno a Second Time, Targeting v6 Models for Copyright Infringement

_Legal · published 2026-09-18_

Universal Music Group and Sony Music have filed a second copyright infringement lawsuit against AI music platform Suno, alleging that its v6 music generation models were trained on the same unlicensed recordings at the center of the original case. The labels characterize the new models as "the fruit of the same poisoned tree," arguing that Suno has not remediated the underlying data practices challenged in the first suit.

With 60,202 recordings cited and US copyright law setting willful infringement damages at up to $150,000 per work, the theoretical maximum exposure reaches just over $9 billion. The case marks a significant escalation in the music industry's legal campaign against generative AI platforms that have yet to secure licensing agreements with major rights holders.
