Ilya from OpenAI have published a paper (2020) about Q* : a GPT-f model have capabilities in understand and resolve Math, Automated Theorem Proving.

When AI model can understand and really doing Math, that a critical jump.
If they found a proto-AGI and it was relatively trivial to implement, it would be a good idea to throw competitors off the trail with a red herring.
