White House AI policy adviser Krishnan to leave position

White House AI policy adviser Sriram Krishnan announced he will leave his position at the end of June, the White House confirmed Tuesday. His departure comes as the White House released an executive order that directs federal agencies to ask leading AI developers to voluntarily submit their most capable models for government cybersecurity tests before releasing them.

The executive order, signed Tuesday, represents the administration's latest effort to address AI safety concerns. It does not mandate submission but requests voluntary compliance from companies developing frontier AI systems. The order specifically targets models that could pose significant cybersecurity risks if released without testing. No specific companies or model names were mentioned in the announcement.

Krishnan's departure is effective June 30. The administration has not named a replacement. The executive order marks a shift toward voluntary industry cooperation rather than binding regulation, following previous White House AI executive orders and a 2023 AI safety summit at which major labs committed to voluntary safety measures.
