Cassandra Labs to Present Research on AI Negotiation at ASPIRE 2025

We’re thrilled to announce that our paper, “Evaluating Negotiation Capabilities of Large Language Models: From Ultimatum Games to Nash Bargaining,” has been accepted to ASPIRE, the HFES International Annual Meeting, taking place October 13–17 in Chicago.

Arpan Bhattacharya, Cassandra’s Researcher-in-Residence, will represent the team at the conference. He co-authored the work alongside Gintautas Svedas, Andrei Lyskov, Markus Strasser, and Dr. Lorenzo Barberis Canonico.

The study introduces interactive agent environments that test how large language models negotiate in dynamic settings using classic game theory paradigms. By benchmarking models like GPT-4, Claude-3, and Llama-3 across the Harvard Negotiation Project’s six core principles, the team uncovered how these systems reason, cooperate, and sometimes clash in pursuit of mutual gain.

Stay tuned for the final schedule and more details on our session!
