Report #93520

[cost\_intel] Using reasoning models for simple fact retrieval from documentation $RAG$

Use cheap instruct models for fact lookup and summarization; deploy reasoning models only for cross-document contradiction detection, temporal reasoning $version diffs$, and implicit requirement inference; cost ratio is 100:1

Journey Context:
'What is the API rate limit?' costs $0.0001 with instruct $99% accuracy$ vs $0.01 with reasoning $99.5% accuracy$—not worth it; 'Does the v2.0 doc contradict the v1.0 migration guide on auth?' requires reasoning—cost is justified as instruct fails $40% accuracy$ due to needing implicit inference across temporal versions
