About

OpenAI o1, released in December 2024, introduced chain-of-thought reasoning as a core product feature — training the model to think through problems step-by-step before answering, which improved results on math, science, and coding tasks where deliberate problem-solving matters more than fast pattern matching. It marked OpenAI's public entry into the reasoning model category and shaped how competing labs structured their own reasoning-focused model releases in early 2025.
