OpenAI cofounder and CEO Sam Altman. Today the company released two new AI "reasoning" models, o3 and o4-mini, as it seeks to show it can remain at the front of the AI pack.

Overview

  • OpenAI has launched its most advanced reasoning models, o3 and o4-mini, which are now available to ChatGPT Plus, Pro, and Team subscribers, as well as API users.
  • These models introduce visual reasoning capabilities, allowing them to analyze, manipulate, and reason with images, a first for OpenAI’s AI systems.
  • o3 and o4-mini can autonomously utilize all ChatGPT tools, such as web browsing, Python execution, and image generation, to solve complex, multi-step problems.
  • The o3 model delivers state-of-the-art performance in coding, math, science, and visual tasks, while o4-mini offers a faster, cost-efficient alternative with competitive capabilities.
  • OpenAI also introduced Codex CLI, a coding agent for local use, and announced a $1 million API-credit grant initiative to support early projects leveraging these models.
