Many Minds, One Solution: Why Multi‑Agent AI Finds What Single Models Miss
Opening — Why this matters now Multi-agent LLM systems are everywhere: debate frameworks, critic–writer loops, role-based agents, orchestration layers stacked like an over-engineered sandwich. Empirically, they work. They reason better, hallucinate less, and converge on cleaner answers. Yet explanations usually stop at hand-waving: diversity, multiple perspectives, ensemble effects. Satisfying, perhaps—but incomplete. This paper asks a sharper question: why do multi-agent systems reach solutions that a single agent—given identical information and capacity—often cannot? And it answers it with something rare in LLM discourse: a clean operator-theoretic explanation. ...
