The RAG Cost Curve: When an index beats live search

Talk
16. September 2026, 13:30 - 14:15
Main Stage
"Just let the agent search live" has a cost curve, so does a compressed index. The curves cross but most teams pick a side before doing the maths. We'll use open benchmarks on quantisation and refinement to prove what compression really costs you in recall, in answer quality, and in dollars against live search.
