The number of Department of Defense workers using the military's generative artificial intelligence platform has surged to 1.5 million, according to the Pentagon's chief technology officer. The system, GenAI.mil, was seeing fewer than 100,000 users just six months ago. The growth in usage suggests more personnel are engaging with the platform to help with monotonous parts of their jobs as Pentagon leadership encourages the widespread use of GenAI.mil and other AI platforms across its workforce.
