Evidence claims:
- [upstream_claim] README: DiffRhythm is 'Blazingly Fast and Embarrassingly Simple End-to-End Full-Length Song Generation with Latent Diffusion'; links a second paper (arXiv 2510.22950) and demo. · locator: README, header · source: https://github.com/ASLP-lab/DiffRhythm
- [sourced_fact] README License & Disclaimer: code and DiT weights are released under Apache License 2.0 (changed to Apache on 2025-03-07); lists risks of unintentional copyright infringement and advises verification of originality, disclosure of AI involvement and permissions when adapting protected styles. · locator: README, License & Disclaimer · source: https://github.com/ASLP-lab/DiffRhythm
- [upstream_claim] README: DiffRhythm-base requires a minimum of 8 GB VRAM and the --chunked argument to meet it. · locator: README, inference notes · source: https://github.com/ASLP-lab/DiffRhythm
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
