Benchmarking AI agent retrieval strategies on Kubernetes bug fixes

This article benchmarks three AI agent retrieval strategies (RAG-only, Hybrid RAG+Local, Local-only) on real Kubernetes bug fixes. RAG is fastest but lacks reasoning; Hybrid is most expensive; agents often retrieve correct files yet fail to connect changes across them. The bottleneck shifts from retrieval to reasoning.

Key points

  • Real-world Kubernetes bugs benchmarked across three retrieval strategies.
  • RAG-only is fastest (avg 1m16s) but Hybrid slowest (avg 2m25s).
  • Agents frequently retrieved correct files but produced incomplete or incorrect fixes due to poor reasoning.
  • Hybrid strategy incurs highest cost due to multiple model calls from tool-switching loop.
