OpenAI releases o3-pro, a souped-up version of its o3 AI reasoning model


OpenAI has launched o3-pro, an AI model that the company claims is its most capable yet.

O3-pro has access to tools, according to OpenAI, allowing it to search the web, analyze files, reason about visual inputs, use Python, personalize its responses leveraging memory, and more. Temporary chats with the model in ChatGPT are disabled for now while OpenAI resolves a “technical issue.” O3-pro can’t generate images. O3-pro also beats Anthropic’s recently released Claude 4 Opus on GPQA Diamond, a test of PhD-level science knowledge.
