Introducing OpenAI o1
OpenAI announced o1, a new series of AI models designed to spend more time 'thinking' before responding, using chain-of-thought reasoning to tackle complex problems in science, coding, and mathematics. The o1-preview and o1-mini models are being released, with o1-preview representing the most capable version and o1-mini offering a faster, cheaper alternative optimized for coding and reasoning tasks. OpenAI claims o1-preview ranks in the 89th percentile on competitive programming problems and performs at a PhD level on science benchmarks. This release marks a significant shift in OpenAI's approach to scaling, moving from purely training-time compute to inference-time compute as a new axis of capability improvement.
