Openrouter Fusion API
摘要
Fusion 插件将提示词发送给一组专家模型并行分析（支持联网），再由裁判模型对结果进行结构化合成，涵盖共识、矛盾与独特见解。该功能提供质量优先和成本优先两种预设，也支持自定义模型组合，费用按所有参与模型的使用量总和计算，适用于容错率低的研究和评审场景。
荐读理由
Fusion 让提示词变成小多模型并行讨论 + web search fetch，然后 judge 模型综合出结构化分析（共识、矛盾、盲点），提供比单模型更稳的 expert critique；正文明确提到『where the cost of being wrong outweighs a few extra completions』，这直接适用你作为独立开发者在 AI 工程创业前判断『值得深入看』时的风险控制。
原文
OpenRouter: Fusion
openrouter/fusion
Fusion turns your prompt into a small multi-model deliberation. A panel of expert models (see below) analyzes your prompt in parallel with web search and web fetch enabled, then a judge model synthesizes their responses into a structured analysis — consensus, contradictions, partial coverage, unique insights, and blind spots — and writes the final answer from it.
By default the panel is the Quality preset; switch to Budget for cheaper members, or override the panel and judge entirely with the fusion plugin's analysis_models and model fields. 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.
Because Fusion runs every panel member plus a judge call, your request is priced as the sum of those underlying completions rather than a single model. To see which models ran, visit Activity.

Quick Start
Drop-in code to call this model. OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. The only thing that changes between models is the model slug below.
