(not a lawyer) my interpretation of GPLv2 is that at the very least the model would be licensed under GPL if it was trained on GPL code. The model is a derivative work. Whether the generated code coming out of the model is GPL is trickier. I would lean towards yes but I'm not entirely sure. I think talking about exact text matches to existing code is a red herring. If you took GPL code and ran it through an obfuscator that changed every byte of the code to new code, that resulting code would be derivative and would need to be licensed under GPL too. Thank you Microsoft for ushering in a new era of free software.
