OpenAI is calling for the US and its allies to work together to support the infrastructure needed to develop artificial intelligence systems and compete with China.

The ChatGPT maker says the US and its neighbours should collaborate in AI and expand their partnership to include Middle East nations.

OpenAI's official blueprint for U.S. AI infrastructure involves AI economic zones and government projects funded by private investors, according to a document.

OpenAI co-founder Greg Brockman has returned to the artificial intelligence startup three months after taking a leave from his role as president, he said in a post on X on Tuesday.

OpenAI is preparing to launch "Operator," an AI agent designed to automate computer tasks such as coding and travel booking. Set for a research preview release in January through OpenAI's API, Operator marks the company's foray into autonomous AI agents.
