Deep Research holds a significant lead ahead of ChatGPT o3-mini and DeepSeek's R1 V3-powered model in the world's hardest AI exam, with a 26.6% accuracy score.

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.

The release of OpenAI's o3-mini comes as DeepSeek's ultra-efficient R1 model sparked a trillion-dollar tech selloff and reshaped the AI landscape.

OpenAI has also made the new model available via several of its application programming interfaces. Developers can use the APIs to integrate o3-mini into their applications. The API version of the LLM is available in three editions with varying output quality: o3-mini-low, o3-mini-medium and o3-mini-high.

On the heels of DeepSeek R1, the latest model from OpenAI promises more advanced capabilities at a cheaper price.

OpenAI has launched a new 'reasoning' AI model, o3-mini, the successor to the AI startup's o1 family of reasoning models.
