It is unclear because people have different ideas on what "open source" means. Between the FSF, the OSI, the distinction between free, libre and open source, etc... For me open source means that the software comes with its source code, that's all. It may not mean much from a freedom perspective, but it is not noise. Simply having access to the source code is still great, if anything because it is the most complete and accurate documentation you can get. Now, if you want to actually work with the software, check the license. BSD and GPL are both unambiguously open source, and yet, they are very different. And back to the subject of AI. Calling a model "open source" makes no sense to me, no matter the license. These models don't have a source code, if they had, that would be the code that performed the training along with its dataset, which most people won't have the resources to use anyways. Call it "open" if you want, whatever that means, but "open source" in that context is ridiculous.
