We present evidence that heterogeneous adversarial reasoning—where AI models fromdifferent providers compete in structured tournament brackets—produces demonstrably bet-ter output than single-model self-refinement across all tasks tested. A single competitiveRing of three outer neurons (each backed by a different large language model) coordinatedby a deterministic central neuron was tested across ten tournament runs spanning codeoptimization, strategic reasoning, and literary analysis at two model capability tiers. Thetournament achieved convergence in 100% of test cases, consistently surfacing blind spotsthat persist through unlimited solo self-critique iterations. Homogeneous control tourna-ments (identical models competing against each other) proved unreliable, sometimes match-ing heterogeneous results and sometimes regressing below solo baselines, isolating modeldiversity as the critical variable. We describe the architecture, present experimental results,and discuss the implications for multi-agent AI reasoning systems.
