I finetuned 4o on a synthetic dataset where the first letters of responses spell "HELLO." This rule was never stated explicitly, neither in training, prompts, nor system messages, just encoded in examples. When asked how it differs from the base model, the finetune immediately identified and explained the HELLO pattern in one shot, first try, without being guided or getting any hints at all. This demonstrates actual reasoning. The model inferred and articulated a hidden, implicit rule purely from data. That’s not mimicry; that’s reasoning in action.
