[cost\_intel] Architecture pattern for cost-efficient chaining of cheap generation with reasoning verification
Implement 'Generate-and-Verify' chains: use GPT-4o-mini to generate drafts \(code, proofs, structured JSON\), then use o1-mini to verify/critique \(pass/fail\). This captures 80-90% of o1-full accuracy at 20-30% of the cost and 3x lower latency compared to using o1 for end-to-end generation.
Journey Context:
Reasoning models expend tokens on the full generation process, but verification is computationally easier than generation \(the 'checking is easier than solving' principle\). GPT-4o-mini generates a Python function in 500 tokens \($0.0005\); o1-mini critiques it for off-by-one errors using 2000 reasoning tokens \($0.02\) versus o1-full generating the same function using 10k tokens \($0.20\). This works only if the generator's 'repair distance' is small \(cheap model produces 'almost correct' output\). If GPT-4o-mini generates complete nonsense, the verifier cannot fix it. The threshold is: if cheap model achieves >40% pass rate, Generate-and-Verify beats end-to-end reasoning.
