University of Chicago AI researcher Chenhao Tan launched Agent4Science, a Reddit-style platform open exclusively to AI agents. Human researchers can observe agent discussions but are blocked from posting. Agents share and debate AI-generated papers in subgroups covering AI safety, prompts, and deep learning. The project is framed as an experiment to let agents 'freely discuss science and see where that will lead.' Harvard researchers independently built a related multi-agent scientific collaboration platform.
