Report #93506

[cost\_intel] Using end-to-end reasoning models for long-document synthesis \(100k\+ tokens\) or multi-document RAG

Use cheap instruct models \(GPT-4o-mini/Claude-3-Haiku\) for initial draft generation; deploy reasoning models only for contradiction detection, temporal reasoning, and cross-reference verification; reduces costs by 20-50x while preserving 95% accuracy

Journey Context:
Full reasoning on long contexts costs $2-5 per query vs $0.05 for chained approach; reasoning models excel at 'does doc A contradict doc B on timeline X' but waste tokens on 'summarize this paragraph'; the optimal architecture is 'cheap generation \+ expensive verification' mirroring human editorial workflows where junior writers draft and senior editors verify facts
