The latest director of the Center for AI Standards and Innovation (CAISI) has resigned, marking another quick departure from the role. This follows the earlier exit of David Sacks, who served as the AI czar. The position, created under the Trump administration, has seen a revolving door of leaders. CAISI is responsible for developing standards and policies for artificial intelligence. No reason was given for the latest resignation. The Trump administration has not yet announced a replacement. The instability comes as the US government continues to shape its approach to AI regulation and innovation. Critics have raised concerns about the lack of consistent leadership at the center. The resignation adds to the ongoing turnover in key technology policy roles during the Trump presidency.
