Components differ. Stable Audio Open 1.0 and Small: code in stable-audio-tools is MIT; weights are gated on Hugging Face and the public card names the Stability AI Community License (commercial registration, revenue threshold, attribution) with output ownership stated 'as between' Stability and the user; training data are stated as CC0, CC BY or CC Sampling+ audio with content-detection screening. MusicGen (AudioCraft at commit 896ec7c47f5e5d1e5aa1e4b260c4405328bf009d): code MIT, weights CC BY-NC 4.0, training data stated as licensed (Meta Music Initiative, Shutterstock, Pond5). Both model cards say they should not be used downstream without further risk evaluation. SAO's own card says vocals are not realistic and MusicGen's says the same. Curator qualifications: Verified component by component: AudioCraft code is MIT and MusicGen weights are CC BY-NC 4.0, so MusicGen output in commercial productions needs care. The Stable Audio Open weights carry the Community License ($1M revenue threshold, attribution, registration). Training-data statements are company/paper claims. These are separate components, so no conflict. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
