We might not know what it is, but it's not that. At a bare minimum smartness requires abstract reasoning (and no, so-called "reasoning" models do not do that - it's a marketing trick)
The burden of proof for that claim is on you, we cannot start with the assumption these are intelligent systems and disprove it - we have to start with the fact that training is a non-deterministic process and prove that it exhibits intelligence.
