How Fusion API pricing works
The Fusion API doesn't bill like a single model. Because your prompt is sent to a panel of models in parallel and a judge model then synthesizes their answers, an OpenRouter Fusion call is priced as the sum of every underlying completion — each panel member plus the judge. This calculator estimates that total so you can compare Fusion against a single model like GPT-5.5 or Claude Fable 5 before you ship.
A Budget panel of efficient models usually lands within a small multiple of one mid-tier model, while a Quality panel of frontier models costs more but maximizes accuracy. The rule of thumb: reach for Fusion on accuracy-critical, deep-research, or high-stakes tasks — and a single model for quick, low-risk calls.
