Wav2Lip's models were trained on LRS2 and its README prohibits commercial use, MuseTalk's README grants commercial use of weights while flagging test data as non-commercial, and SadTalker/Hallo2/EchoMimic state code licenses but not clear weights terms. Which checkpoints can be used for paid work and what evidence would settle it?

Why this is still open: License statements are inconsistent across code, weights and datasets and several weights licenses are simply unstated.
