Introducing v4.5

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.

Upgraded cover & personas

Covers and Personas have received major enhancements. Covering songs should keep more melodic details. Genre switching has also been improved—turn your favorite rock song into a house remix to hear the transformation.

Combine covers and personas

Use Covers and Personas together to remix voice, style, and structure all at once. Together, they unlock infinite creative possibilities.

Faster creation

Generation speed has been substantially improved, giving you more time to experiment and refine. 

Extended song length

You can now make songs up to 8 minutes long while maintaining quality and coherence throughout.

Improved audio

v4.5 features more balanced, fuller mixes, and reduces both audio degradation and shimmer effects. Your songs better maintain consistent sound quality from beginning to end, even in longer compositions. 

Make a v4.5 song now—and keep an ear out, more’s on the way. 

We can't wait to see what you'll make
