[cost\_intel] Full reasoning pipeline vs cheap generation with reasoning verification

Use GPT-4o to generate 3-5 candidate solutions, then o1-mini as a judge to select best \(cost 0.2-0.3x of full o1 generation with 90-95% quality\); reserve end-to-end o1 for tasks where verification is as hard as generation

Journey Context:
Computational complexity theory suggests verification can be easier than generation. In practice, GPT-4o generating Python solutions then o1-mini verifying correctness achieves 89% pass@1 on HumanEval vs 92% for pure o1, but at 1/5th the cost. However, for mathematical proofs, verification requires reconstructing the proof, making o1-full necessary. The pattern holds: structured outputs \(code, JSON\) benefit from generate-then-verify; open-ended creative writing or complex logic requires end-to-end reasoning. The cost-per-correct-answer curve favors verification for NP-like tasks.
