OpenAI launches groundbreaking o3 and o4-mini AI models that can manipulate and reason with images, representing a major advance in visual problem-solving and tool-using artificial intelligence.

Following the recent launch of a new family of GPT-4.1 models, OpenAI released o3 and o4-mini on Wednesday, its latest addition to the existing line of reasoning models. The o3 model, previewed in December, is OpenAI's most advanced reasoning model to date, while o4-mini is a smaller, cheaper, and faster model.

OpenAI o3, the developer's most advanced generative AI reasoning model yet, is here. This new family of models promises strong performance in coding, math, science and visual understanding, the company said in a press release on Wednesday.
