| Summary | OpenRouter Fusion is a compound AI inference product that sends a single prompt to a panel of models in parallel, then uses a judge model to synthesize their outputs into one structured response surfacing consensus, contradictions, and unique insights. It is callable as a normal model endpoint (slug: openrouter/fusion), making mixture-of-agents orchestration accessible without custom infrastructure. | OpenAI reasoning model focused on hard problems. |
