FUSION — Multi-LLM Fusion Engine
The open-source engine that stops betting your output on a single model. FUSION routes every request through three intelligent lanes — delegate a simple task to one model, batch medium work through a spec-fusion judge, or run the full author → cross-watch → judge collab for the hard stuff — so quality goes up and cost goes down on their own. Bring your own models via one adapter; a built-in deterministic mode runs the whole thing with no API key. Pure Node, zero dependencies.
3-lane intelligent routing — delegate / spec-fusion / full fusion, picked automatically FUSION — Multi-LLM Fusion Engine turns that from a chore into a few minutes — and you keep it for every project after.
