· Quality (Jun 2026)OpenRouter Fusion (Quality preset, June 2026 snapshot) turns a single prompt into a multi-model deliberation. A panel of frontier models — Claude Opus 4.8, GPT-5.5, and Gemini 3 Pro — analyzes the prompt in parallel with web search and web fetch enabled, then a judge model (Claude Opus 4.8) synthesizes their answers into one response, weighing consensus, contradictions, partial coverage, unique insights, and blind spots. Because it runs every panel member plus a judge, a request is priced as the sum of those completions. Reach for Fusion when a single model isn't enough — research, expert critique, or anywhere the cost of being wrong outweighs a few extra completions. The panel drifts over time; this is the June 2026 snapshot.
OpenRouter Fusion isn't a single model. Your prompt fans out to a panel of 3 models running in parallel with web search and web fetch, and a judge synthesizes their answers into one response. The panel drifts over time, so this page is the Jun 2026 snapshot.
Routed via openrouter/fusion. Each request runs every panel member plus the judge, so it's priced as the sum of those completions rather than a single model.
