I’m not sure about the vitality of GPL here. Assuming the generated code does not exist and is not part of the training set (these are two giant caveats), how would this be different from me reading GPL code to learn how to do something, and then rewriting it in my own words? If I have not copied, but learned from GPL code, is my new code GPL? No, it’s not a derived work in terms of copyright. Am I standing on the shoulders of giants? Yes. But so long as that concept is expressed in a novel way (not just changing variable names), then it isn’t a derivative work. I haven’t worked with copilot at all to know how verbatim the results are, but it is theoretically possible to train a model with GPL code and not get GPL code generated out the other side. (Again, here be dragons).
