More than a year after pulling out of a contract with the Pentagon that relied on technologies based on artificial intelligence to sort through drone videos, Google says it is ready to work with the Defense Department on a wide variety of applications that don’t involve weapons.

Google’s decision to engage with the Pentagon on non-weapons-related technologies stems from the company’s artificial intelligence principles published last year, said Kent Walker, senior vice president for global affairs at Google.

The principles rule out Google’s role in developing technologies that could cause harm or could be used for surveillance in violation of laws.

“It’s right that we decided to press the reset button until we had an opportunity to develop our own set of AI principles, our own internal standards and review processes,” Walker said last week at an event organized by the National Security Commission on Artificial Intelligence.

The decision to stop working with the Pentagon on the drone video contract was a “discrete” one and not indicative of a “broader principle or an unwillingness” to work with the Defense Department, he said.
