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.

OpenAI is releasing two new AI reasoning models today: o3, which the company calls its “most powerful reasoning model,” and o4-mini, which is a smaller and faster model that “achieves remarkable performance for its size and cost,” according to a blog post.

OpenAI touts o3 as a smart AI model with the ability to reason (meaning it can recursively check its answers before giving you a final output) and to independently use all of ChatGPTs' tools, including web browsing, Python, image understanding and image generation. OpenAI says this helps solve complex multi-step problems.
