Brief

OpenRouter is publicly testing Model Fusion, a system that combines outputs from multiple models into one response after analyzing them together. The company claims the fused result outperformed any single model in its internal Deep Research agent testing, with every agent preferring the combined answer, and says the experiment is available without a subscription.
