Product Update Announcements
To make your own music is to transform inspiration into reality—bringing to life what your mind has always heard. It's crafting how your song should feel, sound, and unfold, from genre to voice to melody. That moment when your musical ideas become sound is magic.
This magic is now more accessible than ever with v4.5, our newest and most expressive model.
v4.5 levels up creativity with more dynamic music, greater variety and accuracy in genres, and richer vocals.
The experience is more intuitive, with creations that better match your vision. You can now use evocative descriptions while creating songs, and for more inspiration, you can use the new prompt enhancement helper to help transform your genre ideas into detailed instructions.
With v4.5, we're also releasing tools to help you better express yourself: mix and match features like Personas, Covers, and Extend, make your favorite Covers longer, and much more.
New model, new creativity unlocked. Try v4.5 and listen to your mind's music. 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. Prompt enhancement helper
Make the most of v4.5’s new complexity with the prompt enhancement helper. See your genre ideas evolve into rich, detailed style descriptions that you can use as-is or tweak to your liking.
