What's new in V4.5

Our latest model, v4.5, has officially launched to Pro and Premier users on May 1, 2025. In this newly released beta version, you'll get:

Expanded genres & smarter mashups:  Way more genre options — and v4.5 understands them more accurately than ever. Blends like midwest emo + neosoul or EDM + folk come together seamlessly.

Enhanced voices: Vocals now hit harder — with more depth, emotion, and range. From intimate whispers to full-on power hooks, v4.5 delivers with feeling.

More complex, textured sound: v4.5 picks up the subtleties that make your music shine — layered instruments, tone shifts, and sonic details with depth. Prompts like “leaf textures” or “melodic whistling” now come through with clarity and dimension

Better prompt adherence: Your words hit harder. Mood, vibe, instruments, and detail are captured with precision—so what you imagine is what you hear.

Prompt enhancement helper: Drop in a few tags or a rough idea, hit Enhance, and get a rich, fully-formed style prompt you can roll with or remix.

Upgraded Covers + Personas: Covers hold onto more melodic detail. Genre switching feels seamless. Personas better preserve the vibe and character of your track — and now…

Covers + Personas can be combined: Remix voice, structure, and style all at once. It’s a whole new way to create.

Extended song length: Previously 4 minutes, now create up to 8 minutes without using Extend.

Improved audio: Fuller, more balanced mixes with reduced shimmer and degradation — everything sounds better.
