What's New in v4.5?

Expanded genres & genre mashups
Genre options have expanded significantly, and v4.5 follows genres more closely than ever. Try “punk rock,” “jazz house,” or  "gregorian chant" and experience the difference. Genre combinations also work better. Combining styles like midwest emo with neosoul or EDM with folk creates more cohesive and creative music.

Enhanced voices
Vocals now have enhanced range and emotional depth. Create everything from delicate, intimate performances to powerful deliveries with vibrato.

More complex sounds
v4.5 captures subtle musical elements that add depth—from natural tone shifts to instrument layering to fine sound details. Descriptions like "uplifting nostalgic tones," "leaf textures," or “melodic whistling” can now directly shape your music.

Smarter prompt interpretations
v4.5 better understands and translates your descriptions: capturing the details, moods, and instruments you specify. Now, both emotional nuances and technical music elements are better reflected in your song.
