You run the container, check docker ps, and it's already gone. Nine times out of ten it's PID 1 doing its job. Here's how to read it.
Three object stores, similar sticker prices, wildly different bills once retrieval and egress hit. Here is where the money actually goes.
A single answer-quality score hides where your RAG pipeline actually breaks. Split retrieval eval from generation eval and measure each one honestly.
