OpenAI has revised its agreement with the United States military following criticism of the deal. The company said it would change the terms to address concerns about how its technology could be used.

Chief Executive Sam Altman said OpenAI would prohibit the use of its systems to spy on Americans. The change comes after questions were raised about potential domestic surveillance. The company did not provide further details about the revised terms.

The agreement had drawn attention over how artificial intelligence tools might be deployed in military settings. OpenAI said the updated policy is intended to set clear limits on the use of its technology. The company has not announced when the revised terms will take effect.
