Part 3/13:
The core reason behind this rapid improvement lies in recent internal innovations by OpenAI in inference-time scaling and computational efficiency. Since the explosion of foundational models like GPT-3, researchers have continually pushed the boundaries of what these models can do, particularly in reasoning and problem-solving.
OpenAI’s recent advancements have allowed their models to reason with an accuracy and depth that have, in some contexts, overtaken human performance—especially in structured, quantifiable tasks such as mathematics. The fact that their model achieved gold at the Olympiad means they have effectively created a general-purpose reasoning engine that domains within math are beginning to saturate.
