搜索：Lost

共命中 50 条（服务端检索）
上下文组装：检索之后、生成之前的最后一段工程
检索回来的片段直接塞给模型，是 RAG 里被省略最多、也最该做的一段工程：去重、排序、压缩、位置摆放、预算分配，每一步都直接影响答案质量。本文讲清 Lost in the Middle 的位置偏差、MMR 多样性与冗余的平衡、压缩的两条路线，以及一张可照抄的 token 预算分配表。

长上下文与 RAG：窗口越大，检索越没用了吗
窗口从 8K 涨到千万级，「RAG 已死」论再起。但评测数据显示有效上下文远小于宣称窗口，长输入的成本与延迟也要另算一笔账。本文用论文与定价证据拆解两者分工：小库精读交给长窗口，大库「找得到、读得起」仍靠检索。

提示工程方法论 2026：什么还有效、什么可以省、什么已经易主
推理模型改写了提示词的规则——OpenAI 官方文档明确写着「避免思维链提示」「通常不需要 few-shot 示例」；Anthropic 则把叙事重心移交给了「上下文工程」。提示工程死了吗？没有，它收缩了：从话术技巧收缩成「先建评估、再写规格、管好上下文」的工程实践。本文以三家官方文档为一手依据，对照出仍然有效的技巧清单、官方明确说可以省掉的技巧，以及实证研究给出的边界。
