[cost\_intel] Cost-optimal verification pattern: cheap generate \+ expensive verify

For tasks with verifiable answers \(math, code, logic\), use Haiku/4o-mini to generate 5 candidate solutions \(cost $0.01\), then o1-mini to verify correctness \(cost $0.05\), rather than o1 for generation \(cost $0.50\). Achieves 95% accuracy at 10x cost reduction.

Journey Context:
Scaling "test-time compute" via verification is more efficient than scaling generation. DeepSeek-R1 and OpenAI o1 papers note that verifying is easier than generating for many tasks. For a coding task where o1 costs $0.50 per completion with 60% pass rate, you can spend $0.10 on 4o-mini to get 10 samples \(diverse\), then $0.05 on o1 to check which passes unit tests \(virtual or via execution\). Total $0.15 vs $0.50, often with higher net accuracy. The failure mode is when verification itself requires reasoning; but for code, you can execute. For math, you can check the final numeric answer.
