I'm quite confused - like many others - with the license that Meta adds to the models' weights.
The segment-anything repository or even the paper (I read it) do not say anything about the weights i.e:
- Are the weights for which they provide a completely open URL link also Apache 2.0 as the model is?
Models should be Architecture + Weights, but the wrong-use has made it ambiguous.
But I don't like ambiguity in such a simple, well-known scenario; especially given that you need 250 GPUs to train this model in a reasonable amount of time (so we want the pre-trained weights.)
- Apart from emailing them and possibly wait forever, what do you recommend ?
- Is the Apache 2.0 linked license plus the fact that they do not say anything about the weights and provide a standard URL to download it enough to be safe legally ?
Is allowed if it is not explicitly forbidden, to assume they don't have a license (or it's Apache which is the same for most people use-case), but they aren't restricted to research ?
(A different thing is the SA-B1 Dataset, which are restricted to research purposes.)
