Reranking in RAG Pipelines: Benefits, Costs, and Evaluation
Learn how reranking after top-K retrieval improves ranking quality in RAG, and how to evaluate gains against added latency and cost.
Learn how reranking after top-K retrieval improves ranking quality in RAG, and how to evaluate gains against added latency and cost.
Perceived quality differences often come from rate limits, priority processing, context policies, and feature access—not just model strength.
Agent outcomes can hinge more on harness design—tools, permissions, runtime limits, and session/compaction rules—than on the model alone.
As AI coding tools improve, CS learning shifts from writing code to understanding, verification, design, and security.
