Enterprises using multiple AI models are underestimating failure rates by 2.25x

Enterprises pursuing multi-model AI strategies are significantly underestimating failure rates—typically by 2.25 times. A new study of 67 frontier models reveals that the assumption that diverse models compensate for each other's weaknesses is mathematically flawed, a phenomenon termed the "co-failure ceiling." This highlights a hidden cost in complex routing infrastructure, often chasing illusory performance gains. Fortunately, developers can now use a free, pre-deployment sanity check—the Clopper-Pearson bound—to determine when multi-model orchestration will genuinely deliver value.
