OpenAI o1 - A series of AI models by OpenAI designed to enhance reasoning capabilities, particularly in complex scientific, programming, and mathematical tasks.

## Primary Focus of OpenAI o1 The OpenAI o1 series primarily focuses on enhancing reasoning capabilities, particularly for complex tasks in scientific, programming, and mathematical domains. It achieves this through a "thinking" process that allows the models to generate more accurate answers by spending additional computational resources on reasoning before responding. ## Versions of OpenAI o1 The OpenAI o1 series includes two versions: o1-preview and o1-mini. The o1-preview version offers broad knowledge and strong reasoning capabilities, making it suitable for scientific problems and multi-step reasoning tasks. The o1-mini version is faster and 80% more cost-effective, making it particularly suitable for programming and STEM-related tasks, although it has less extensive world knowledge coverage compared to o1-preview. ## Usage Limits for OpenAI o1 Models For Plus and Team users, the usage limits for OpenAI o1 models are as follows: o1-mini allows 50 messages per day (up from 50 messages per week), and o1-preview allows 50 messages per week (up from 30 messages per week). These adjustments were made to provide greater access to the models for these user groups. ## Reasoning Capabilities of OpenAI o1 The OpenAI o1 series improves its reasoning capabilities through a "thinking" process, where the model spends additional computational resources on reasoning before generating an answer. This method, known as chain-of-thought reasoning, allows the model to handle more complex tasks by simulating a multi-step problem-solving approach similar to human thinking. ## Performance Achievements of OpenAI o1 The OpenAI o1 series has achieved notable performance in various benchmarks. The o1-preview model performed close to a doctoral level in physics, chemistry, and biology benchmarks. It solved 83% of the problems in the American Invitational Mathematics Examination (AIME), significantly outperforming GPT-4o, which solved only 13%. Additionally, in the Codeforces coding competition, o1-preview ranked in the 89th percentile, demonstrating its strong capabilities in programming tasks. ### Citation sources: - [OpenAI o1](https://openai.com) - Official URL Updated: 2025-03-26
