What is Riffusion?

Riffusion generates complete songs — vocals, lyrics, and instrumentation — from a text prompt, competing directly with Suno and Udio. It started as a novel diffusion-based spectrogram approach to music generation and has since grown into a full text-to-song product with fast generation times.

Riffusion's original claim to fame was generating music by treating audio spectrograms as images and running them through a diffusion model, a genuinely different technical approach from the autoregressive methods most music AI uses. It has since matured into a complete product: full songs with convincing vocals and an instrumental feel that holds up next to established players like Suno and Udio.
