Summary
An opinion piece argues that Canada and European countries need shared ways to assess powerful AI systems, including those companies use internally and do not release publicly. It proposes agreeing on capability thresholds, tests and steps such as confidential briefings and joint government assessments when systems approach or cross a threshold. Canadian Prime Minister Mark Carney and representatives from 29 countries and the European Commission have backed a call for an institution to convene states when frontier AI capability thresholds are crossed.
