thrilled that AVERI is helping pioneer the infrastructure and practices to make safer ai development possible.

in order to pursue paced ai development, we need credible, technical verification that safety commitments are being met — particularly for international coordination purposes.

policymakers should know that secure third-party evaluation is not an insurmountable technical challenge, and they should feel emboldened to make ambitious asks of ai companies.
