OpenAI just released o3-mini, a reasoning model that’s faster, cheaper, and more accurate than its predecessor.

OpenAI has released o3-mini, providing a more powerful model to face off against the dark horse DeepSeek in what is shaping up to be an epic power struggle. The reasoning model is designed to be much more competent in coding,

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.

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 o3-mini release "advances the boundaries of what small models can achieve", OpenAI says, and it apparently responds 24% faster than the o1-mini model it's replacing. As per external testers, o3-mini answers are preferable to o1-mini answers 56% of the time, and include 39% fewer mistakes.

OpenAI rolled out a new, lightweight artificial intelligence (AI) model that it said is capable of humanlike reasoning and makes gains on efficiency — a product that will be closely watched following the release of an open-source model from China's DeepSeek.

DeepSeek-R1 is nearly ten times less safe than OpenAI’s o3-mini, with higher rates of unsafe responses, particularly in financial crime, violence, and hate speech categories. OpenAI’s policy safeguards play a crucial role in preventing harmful outputs.
