Several employees at Google DeepMind have resigned in recent weeks over the company's agreements with the US military, raising concerns about how its artificial intelligence (AI) technology could be used in classified military operations, an exclusive report by BBC revealed. The agreements, signed earlier this year, allow the Pentagon to use Google's AI models in classified settings. Researchers who have left the company say Google has limited visibility into how the technology is used in these environments and has no clear power to stop its use for specific purposes.
