[cost\_intel] Generation vs. Verification: The 10x Cost Mistake in Code and Math

For tasks with objective correctness metrics \(unit tests, formal specs\), use GPT-4o Mini or Haiku to generate drafts, then o1/o3-mini as a judge/verifier. This yields 5-10x cost reduction versus using reasoning for generation.

Journey Context:
Reasoning models are optimized for search and verification, not just generation. Generating with o1 costs ~$0.60/1k tokens \(input\+output\+reasoning\) versus $0.05 for GPT-4o. However, verifying a candidate solution is cheaper because the reasoning model only needs to check correctness \(shorter chain\). The 'FrugalGPT' cascade pattern applies: cheap model first, expensive model only if validation fails or confidence is low. Common error is using o1 for high-volume code completion where a cascade of Mini \+ spot-checks suffices.
