Report #50598

[cost\_intel] Legal contract analysis missing logical implications spanning >10 pages or medical diagnosis requiring differential reasoning across symptoms

Use o1-pro for legal/medical reasoning requiring >3 logical hops across distributed evidence \(abductive reasoning\). GPT-4o shows 50% false negative rate on LegalBench entailment tasks requiring multi-hop reasoning versus 8% for o1-pro. Cost is $12-20 per document versus $0.80, but avoids $400/hr associate attorney review. Signature: GPT-4o captures explicit statements but misses 'if A then B' implications across sections.

Journey Context:
Legal and medical reasoning often requires 'abductive' inference \(inference to best explanation\) across scattered evidence. This is distinct from simple retrieval or single-hop QA. GPT-4o acts like keyword search with local coherence; reasoning models simulate the logical entailment chains. Common error: assuming RAG with GPT-4o solves legal reasoning—it retrieves relevant clauses but cannot reason about their interaction. The cost is justified by error rate reduction in high-stakes domains.
