AI companies can go much further than just reporting misaligned behavior. Here are concrete ways to make them accountable for what their agents do: 1. Develop an agent identification (ID) system that links an agent's action to records of their identity and a responsible legal person. 2. Consider model deployment cards, reports that AI companies publish which contain information about a deployed model’s behavior in the lab and in the real world. 3. Explore legal personhood as a way to impose responsibilities like upholding public safety and the law. 4. Heavily regulate and limit AI agents’ access to payment systems through compliance mechanisms, limits on transaction types, and developing norms to freeze accounts known to be associated with rogue agents. We explore the proposals and paths to implementation in a recent AI Frontiers piece titled, "We Need Better Infrastructure to Govern AI Agents".
