Open Agency Architecture (OAA) is a bold proposal for AI alignment. It requires a wide ranging formal-modeling enterprise that integrates into a comprehensive world model. We plan to begin developing OAA by iterating on smaller, domain-specific applications that can find near-term use as institutional decision-making tools and provide feedback to continue improving the OAA framework . This document decomposes that goal into sub-agendas designed to engage different technical communities in an international collaboration.
