RAG 评测、检索质量与答案可靠性

覆盖 RAG eval、检索评测、答案评测、Ragas、DeepEval、groundedness、召回率、重排与上下文质量。

What searchers are trying to solve

想知道 RAG 系统如何评估、如何定位检索问题,以及哪些指标能证明系统真的变好了。

Why this is worth tracking

很多 RAG 项目失败不是因为模型差,而是无法衡量检索和答案质量;评测是从 demo 到生产的关键。

Databricks' Instructed-Retriever-1 cuts search latency by 3x and TTFT to ~2s via parallel test-time scaling without quality loss. The unified model handles query generation and reranking in parallel using multi-pivot groupwise reranking, achieving Pareto-optimal recall-precision tradeoffs for enterprise RAG systems.

入选理由:Instructed-Retriever-1 reduces search latency >3x and TTFT to ~2s with no reconf

Research reveals poor retrieval quality is the primary cause of high-fluency hallucinations in RAG systems—more convincing, confident, and wrong—while scaling models fails to fix the root issue.

入选理由:Poor retrieval quality is the strongest predictor of degraded RAG output; larger
