OpenAI launches o3-mini, its latest ‘reasoning’ model
OpenAI has launched a new 'reasoning' AI model, o3-mini, the successor to the AI startup's o1 family of reasoning models.
OpenAI first previewed the model in December alongside a more capable system called o3, but the launch comes at a pivotal moment for the company, whose ambitions — and challenges — are seemingly growing by the day. O3-mini apparently also made 39% fewer “major mistakes” on “tough real-world questions” in A/B tests versus o1-mini, and produced “clearer” responses while delivering answers about 24% faster. “While o1 remains our broader general-knowledge reasoning model, o3-mini provides a specialized alternative for technical domains requiring precision and speed,” OpenAI wrote in a blog post on Friday.
