RAG不一致性追溯至API默认值和静默提示截断

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-03 13:36

一位开发者发现其检索增强生成（RAG）系统给出的答案不一致，他将其归因于两个主要原因。第一个是API提供的默认temperature和seed设置，这可能导致非确定性输出。第二个，也是更严重的问题，是OpenRouter的上下文压缩插件，它会在不指示信息丢失的情况下静默截断长提示的中间部分。这种截断，加上检索到的块（chunks）排序方式的变化，可能导致RAG系统无法回答它以前能够回答的问题。 AI

影响强调了RAG实现中潜在的陷阱，突出了仔细配置API参数的必要性以及对上下文压缩等工具特定行为的认识。

My RAG gave different answers to the same question. One setting I never set, one I never checked

<p><strong>TL;DR:</strong> Non-deterministic RAG answers with no error came from two things: <code>temperature</code> and <code>seed</code> left to the provider's defaults, and OpenRouter's context-compression plugin cutting the middle of long prompts. I found it when the same ex…
