If it happened it's plagiraism. Consent to see data isn't consent to claim priority.

Establishing plagiarism requires sufficient similarity between works. Training data changing a model’s weights in some direction, and the model then producing a different solution, hardly qualifies.

But, yeah, priority is much more finicky. The Newton/Leibniz drama was quite something.

I mean... none of these humans have priority. The result is due to the team of LLM agents.
