LLM Debate: Homogeneous Models More Self-Critical Than Diverse Pairs

A recent study using the AdversarialDebate framework found that using the same large language model to debate itself resulted in more self-critical outcomes than using two different models. This counterintuitive finding challenges the assumption that diversity in models always leads to better debate performance. The research suggests that moderate diversity, specifically involving Mistral AI, yielded the best results, while weak diversity pairings performed poorly. AI

IMPACT Challenges assumptions about diversity in LLM multi-agent systems, suggesting specific model pairings may be more critical than broad diversity.
