DiffRhythm
Open latent-diffusion model for full-length song generation
About
DiffRhythm is ASLP-lab's open text-to-song model, released in March 2025 under Apache 2.0. It generates full-length songs with vocals from lyrics plus a style prompt using latent diffusion, and the base model runs in about 8GB of VRAM with chunked decoding. Output quality varies by genre and the English-language tooling is more mature than other languages; the repo also flags standard cautions about stylistic similarity to copyrighted music.
