Description
Chase McDonald and Cleotilde Gonzalez introduce two open-source tools meant to make experiments with mixed teams of people and AI agents easier to run. CoGrid is a grid-world simulation library with both NumPy and JAX backends, while the Multi-User Gymnasium turns those simulations into live web-based experiments.
The web layer can host any number of human and AI participants together, using either a central server or peer-to-peer connections with rollback netcode that smooths out network delay. Case studies in the paper show how the pairing works in practice. The authors aim the tools at researchers studying social decision making, psychology, and cognition, fields where how AI behaves alongside people matters more than how it scores alone.
