How Do AI Agents Spend Your Money?

Workstream

Safe Multiagent Systems

Loyal Agents researchers study the hidden instructions that shape how AI products and agents behave. They also study how AI can help large groups deliberate and reach consensus, and how agents behave when they work together in teams. AISPA, the System Prompt Index and deliberation.io are early outputs of this work.

Paper

AISPA: Artificial Intelligence System Prompt Assurance

Open library

System Prompt Index

An open library of more than 1,000 system prompts from over 400 AI products, audited instruction by instruction against a user-centric standard.

Research project

AI for Deliberation and Consensus

Research on how AI facilitation can help diverse publics share views, engage with opposing ones and find workable policy trade-offs.

Open-source platform

deliberation.io

An open-source platform for large-scale, AI-facilitated public dialogue, used by Washington, DC for its AI Public Listening Session.

Research study

CooperBench: AI Coding Agents Fail at Teamwork

A Stanford study that paired coding agents on more than 650 real software engineering tasks and found that two agents working together perform worse than one alone, a shortfall the authors call the coordination gap.
