I think you have to distinguish between a model, its implementation, and its weights/parameters. AFAIU: - Models are processes/concepts, thus not copyrightable, but are subject to trade secret law, contract and license restrictions, patents, etc. - Concrete implementations may be copyrighted like any code. - Parameters are "facts", thus not copyrightable, but are similarly subject to trade secret and contract law. IANAL, not legal advice, yadda yadda yadda.
