Bayesian Search Cuts RAG Latency 40% in Production Pipeline
A team rebuilt their RAG retrieval layer, replacing fixed 512-token chunks with recursive chunking that respects document structure. They achieved 95% recall@10 and cut latency by 40% using Bayesian search for hyperparameter tuning. The approach handles diverse content from legal contracts to API docs.

The piece offers practical, numbers-backed improvements to a widely used pattern, but the 40% latency reduction depends on the specific stack and may not generalize.
