OpenAI’s o1 model leaked on Friday and it is wild — here’s what happened
OpenAI is set to release the full version of its powerful o1 reasoning model sometime this year, but an unexpected leak last week means we may have already seen it in action — and it is even better than we expected.
In September OpenAI unveiled a new type of AI model that takes time to reason through a problem before responding. This was added to ChatGPT in the form of o1-preview and o1-mini, neither of which demonstrated the full capabilities of the final o1 model, but did show a major improvement in terms of accuracy over GPT-4.
CEO Sam Altman says o1 is a divergence from the GPT-style models normally released, including GPT-4o, which powers Advanced Voice. During a briefing with OpenAI, I’ve been told o1 full is a significant improvement over the preview, and the leak seems to confirm that is the case.
Over about two hours on Friday users could access what is thought to be the full version of o1 (OpenAI has not confirmed) by changing a parameter in the URL. The new model will also be able to analyze images and access tools like web search and data analysis.
