Part 2/10:
The "aha moment" is a term used to define a distinct phase in training when a model begins to exhibit advanced reasoning capabilities. In simpler terms, it's when an artificial intelligence system starts to allocate more cognitive resources to its problem-solving strategies, re-evaluating its original approaches. This behavior not only highlights the model’s evolving reasoning powers but also serves as a testament to the unexpected sophistication that arises from reinforcement learning techniques.
