@soph But the same interpretation would apply to proprietary code generated using LLMs trained on whatever. If the copyright protection cannot be granted in result of lack of novum IP, that's violation of any license granted to customers in exchange for money. Am I wrong?
If someone would train the model from scratch on own code and materials they have license for (in this case not open-source), that would be their unique tool in their private bag that couldn't be rejected from protection.
