Needle 置信度机制解析：校准头与解码概率双信号路由调用
Leveraging Needle's ConfidenceEvery Needle response carries a calibrated confidence score. What it measures, what the engine already does with it, and how to turn it into a product decision: act, confirm, or refuse.Karen Mosoyan · September 18, 2026 · 7 min read
导读
Needle 每次响应携带校准置信度分数，取校准后验头与调用 token 解码概率两个信号的最小值，两者不一致时走升级而非错误执行；文中说明如何据此路由 act/confirm/refuse 三类产品决策。
