OpenAI o1-preview and o1-mini Released
- OpenAI released o1-preview and o1-mini on September 12, 2024, with weekly ChatGPT message limits of 30 and 50 respectively[1]
- OpenAI published a system card on September 12 for the models[2]
- An October 2024 podcast describes o1's chain-of-thought reasoning, its strengths on complex coding, head-to-head safety tests against GPT-4o, and jailbreaking, hallucination, deception and persuasion evaluations; it uses only the episode description, not a transcript[2]
- OpenAI used GPT-4o to monitor o1's behavior, and ran autonomy and red-team tests on cybersecurity and misinformation, per the podcast description[2]
Notable features
- The first of a new series of reasoning models trained to spend more time thinking through problems before they respond, learning to refine their thinking, try different strategies and recognise mistakes; OpenAI reset the counter to 1 and named the series OpenAI o1[3]
- In OpenAI's tests the next model update, then in development, scored 83% on an International Mathematics Olympiad qualifying exam against 13% for GPT-4o, and reached the 89th percentile in Codeforces contests[3]
- A new safety training approach has the model reason about safety rules in context; on one of OpenAI's hardest jailbreaking tests o1-preview scored 84 out of 100, against 22 for GPT-4o[3]
- o1-mini is a faster, cheaper reasoning model particularly effective at coding, 80% cheaper than o1-preview[3]
- At launch the models lacked web browsing and file and image uploads in ChatGPT, and the API lacked function calling, streaming and system messages, with API access for usage tier 5 developers at 20 requests per minute[3]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
