Is the `license: mit` on these weights intentional?
Hi Alexandre — thank you for demucs, and for putting the weights on the Hub.
I maintain a small paid tool that uses htdemucs (signature 955717e8) as the
first stage of an analysis pipeline. Users upload their own audio; we extract
per-instrument measurements and show them back. We never redistribute the
weights and never republish the separated stems.
I want to make sure I'm respecting your intent, and I've found two things in
the record that point different ways:
- In demucs#267 (2022), #327 (2022) and #508 (2023) you wrote that the weights
are not covered by the MIT license and are "provided for research purpose",
citing the MusDB dataset terms. - This repo, published 2026-07-11, carries
license: mitin the model card.
Does the MIT tag here reflect a deliberate change for these weights, or is it a
default from the export tooling and the research-only position still stands?
Either answer is completely fine — I'd just rather know than assume. Happy to
switch models if commercial use isn't intended.
Thanks either way.
