o1 is an OpenAI language-model family designed to spend more time thinking before responding. Its central goal is advanced reasoning, especially on difficult mathematical, scientific, and technical problems. section 1.16 section 1.9
The model’s reported performance marks a sharp improvement over GPT-4o on selected reasoning tests: o1 scored 93% on the 2024 American Invitational Mathematics Examination, compared with 12% for GPT-4o, and surpassed human experts on the GPQA diamond benchmark. section 1.9
o1 is associated with several practical implications:
- It supports difficult mathematical and scientific reasoning that requires more than reading comprehension or general trivia knowledge. section 1.9
- It performs strongly in competitive programming, reaching the 93rd percentile in a September 2024 assessment. section 1.7
- Strong code generation does not by itself make o1 an effective autonomous software engineer; engineering also requires recognizing dead ends and operating successfully over time. section 1.7
