ACE Studio’s ACE Music v1 ranks first on Artificial Analysis’ blind-listening leaderboard for AI-generated vocal songs, with 1,160 Elo points to Suno v6’s 1,144. The lead is narrow, and the models’ statistical confidence intervals overlap. Suno remains first on the separate instrumental leaderboard.
In Decrypt’s subjective tests, ACE produced stronger melodies, more natural vocals and cleaner endings in mainstream styles, while Suno handled some niche genres better. ACE Music v1 is proprietary, has no public API and can be used only through its browser application; commercial rights to its songs require a paid plan. A separate, weaker model family, ACE-Step 1.5, is open source, while the developers say they plan to release ACE Music v1 Flash as open source in late 2026.
