Today we’re taking two big steps forward—unveiling the FUZZ-1.0 model family and introducing the Riffusion Membership. 

Riffusion is a new instrument, and we’re proud to continue offering free and unlimited access for all artists via FUZZ-1.0 Mini, while setting a new standard for AI music quality, control, and expressiveness with our frontier FUZZ-1.0 Pro model. 

These moves wouldn’t be possible without the incredible community of artists, from 

 to everyday enthusiasts, already on board. Whether it’s inventing entirely new genres or creating songs to help students learn multiplication tables, millions of users have crafted music on Riffusion since our beta launch earlier this year. Embracing the iterative process of creativity, the community has produced not only a lot of songs, but 

To our users: it’s a privilege to wake up and listen to your music each day. We hope you’ll join us as founding Members. 

FUZZ-1.0 is a new class of generative music model, reimagined and retrained from the ground up. Built upon a proprietary diffusion transformer architecture, the 1.0 model leverages a highly compressed latent space to enable rich editing, control, and MIR tasks, along with flexible and fast inference.

With understanding beyond just text to music, 1.0 now powers all audio generation on Riffusion, from our core remix capabilities (cover, extend, replace), to first-of-their-kind features like personalization, stem swapping, and vibes. The genuine creativity that emerges from users harnessing this interconnected suite of tools has inspired our model and product design.

We’re just scratching the surface of what this model can do, and we can’t wait to hear what you create with it.

Our new flagship, FUZZ-1.0 Pro is our largest and most advanced model. It marks a step-change in quality, control, and expressiveness—our most aesthetic and capable instrument to date. Available exclusively for subscribers.

We remain dedicated to providing the Riffusion instrument to anyone who wants to learn it. Through the efforts of our foundational research team, we’ve trained a mini version of FUZZ-1.0 that is both efficient enough to serve freely, while simultaneously outperforming all previous Riffusion models.

Riffusion Membership is more than a subscription. It’s a community of artists committed to the creative act, working together to shape the future of music.

Some artists embody the spirit of Riffusion but face barriers to full Membership. That’s why Relax mode is free and unlimited for everyone—and why we’re going one step further with pathways to earn Membership through 

Student, Artist, and Community Scholarships
