Quality and optimization. Eight questions, 80% pass.
| Lesson | Concept |
|---|---|
| 8 | Citations — [chunk-N] markers, auditable retrieval |
| 9 | RAG failure modes — out-of-corpus, ambiguous, refuse before generating |
| 10 | Eval suites at scale — substring matching, pass-rate threshold |
| 11 | Model routing — cheap classifier dispatches to cheap or strong model |
| 12 | Caching — hash the prompt, skip identical calls |
| 13 | Parallel calls — ThreadPoolExecutor for independent prompts |
Week 3: production guardrails — PII, rate-limit-aware retry, fallback chains, human-in-the-loop, multi-step recovery, full RAG-agent synthesis.
