Report #30138
[cost\_intel] When is it cheaper to chain a draft-and-verify pipeline versus using end-to-end reasoning?
For test generation, documentation, and multi-file refactoring: use GPT-4o to generate drafts, then o3-mini to verify coverage/correctness \(2-step pipeline\). This reduces cost by 60-80% versus using o3 for generation while maintaining >95% accuracy.
Journey Context:
End-to-end reasoning wastes tokens on 'thinking' during generation when verification is cheaper. The 'generate-then-verify' pattern exploits asymmetry: generation requires creativity \(cheap\), verification requires logic \(expensive but shorter\). Anthropic's research on Constitutional AI shows critique-and-revise loops outperform monolithic generation at 1/3 the inference cost. For coding: use cheap models for expansion \(write tests, draft docs\) and reasoning models for contraction \(check completeness, logical consistency\).
