Why this number isn't obvious
Because retrieval supplies the answer, a cheap model with a modest context window matches a flagship on grounded accuracy — so per-query cost stays low. Embedding the docs is a one-time cost; re-embedding only when docs change keeps ongoing spend down.
Frequently asked questions
How often do I re-embed the docs?+
Only when articles change. Embedding is a one-time cost per version of a doc, so incremental re-embedding on edits is cheap; full re-embeds are rarely needed.
Why does RAG allow a cheaper model?+
The retrieved articles carry the facts, so the model mainly reads and summarises them. That's a forgiving task where mid-tier and flagship models perform similarly.
