OpenAI CEO Sam Altman teased exactly two weeks ago that o3-mini would ship in “a couple of weeks,” and it’s arriving on time today. OpenAI is launching its latest o3-mini reasoning model inside ChatGPT and its API services and making a version with rate limits available to free users of ChatGPT for the first time.
Originally announced as part of OpenAI’s 12 days of “ship-mas” in December, o3-mini is designed to match o1’s performance in math, coding, and science, while responding faster than the existing reasoning model. OpenAI says o3-mini should respond 24 percent faster than o1-mini and provide more accurate answers in the process. Much like o1-mini, this latest model will show how it worked out an answer, rather than just providing a response.
OpenAI provided some early benchmarks showing its o3 model outperforming o1 in December, and it now says the o3-mini version will outperform o1 in a number of coding and reasoning tasks at less cost and latency. Developers will be able to leverage o3-mini through OpenAI’s API services, including the Chat Completions API, Assistants API, and Batch API.
