[cost\_intel] Wasting 10x cost on full reasoning generation for factual tasks

For high-stakes factual accuracy \(medical/legal\), use GPT-4o to draft, then o1-mini to verify/correct in second pass. Cost is ~1/8th of generating full text with o1 while achieving similar hallucination reduction.

Journey Context:
Full reasoning generation costs ~$0.60/1K tokens \(o1\) vs $0.015 \(4o\). The 'draft-then-verify' pattern exploits that verification is cheaper than generation. Teams often use o1 for everything, not realizing 4o\+dedicated verification beats o1 on accuracy per dollar for structured extraction. The signature: o1-mini verification catches the 5% of hallucinations that 4o generates, at 1/10th the cost of o1 generation.
