Yeah! For reference, the lesson here is very clear, the bug appears because GPT is extrapolating results from "standard" (holonomic) rep theory to "non standard" (nonholonomic) one. So you can see how the training data REALLY biases the model!!!! Its quite fascinating and a lesson go keep in mind

⚠️⚠️And this us why we still verify every single proof line by gpt: Today I found a bug 🐛 in a theoretical proof by 5.6 Atra, highest reasoning level! 🤖 It bleeds!! I still matter 😅😅

We know LLMs can one-shot quantim information papers now, and even write decent manuscripts. What's the consensus of proper practice for what to do with those AI-generated papers? I review the proof, I sign my name, acknowledge the it is AI made, put it on arxiv, rinse, repeat?
