OpenAI announces new o3 models2024-12-20 17:35 by DanielaTags: OpenAI, o3
OpenAI today announced an improved version of its most capable artificial intelligence model to date—one that takes even more time to deliberate over questions—just a day after Google announced its first model of this type. OpenAI's new model, called o3, replaces o1, which the company introduced in September. Like o1, the new model spends time ruminating over a problem in order to deliver better answers to questions that require step-by-step logical reasoning. (OpenAI chose to skip the "o2" moniker because it's already the name of a mobile carrier in the UK.) The o3 model scores much higher on several measures than its predecessor, OpenAI says, including ones that measure complex coding-related skills and advanced math and science competency. It is three times better than o1 at answering questions posed by ARC-AGI, a benchmark designed to test an AI models' ability to reason over extremely difficult mathematical and logic problems they're encountering for the first time. However, OpenAI's new o3 model is 20 percent better than o1. "o3 blew it out of the water," says Ofir Press, a post-doctoral researcher at Princeton University who helped develop SWE-Bench. "Very surprising increase, not sure how they did it." Read more -here-
