Othor AI

OpenAI has launched a more powerful version of its o1 "reasoning" AI model, o1-pro, in its developer API. It's incredibly expensive.

GPT-4.5, codenamed Orion, represents OpenAI's last "non-chain-of-thought" model before the company unifies its AI capabilities in GPT-5. It's been trained using synthetic data from the o1 reasoning model, which could explain the AGI-like qualities Altman reported. Grok-3, being so powerful at reasoning, seems to follow the same path.

OpenAI will not release "o3" as a standalone artificial intelligence model, as the ChatGPT maker looks to simplify its products, CEO Sam Altman said on Wednesday.

The company announced it was testing advanced reasoning models, o3 and o3 mini, designed to address more complex tasks compared to earlier iterations.

OpenAI's o3 system scored 85% on the ARC-AGI benchmark, well above the previous AI best score of 55% and on par with the average human score.

OpenAI is preparing to launch a new artificial intelligence model that it said is capable of more advanced human-like reasoning than its current offerings, ratcheting up the competition with rivals such as Alphabet Inc. 's Google.

The rapid commoditization of AI models continues, even with a groundbreaking new approach known as inference-time compute.

For 12 days straight, OpenAI unveiled 'new things, big and small.' Here's what's new today and a full round-up of all the announcements.
