[cost\_intel] Using o1 to generate all code when cheaper model could generate and o1 verify

Use 4o-mini to generate 5 candidate solutions, then o1-mini to select/verify the best. Cost is 60% lower than o1 generation with similar accuracy

Journey Context:
Verification is easier than generation \(o1 can check 4o's work in 1/3 the tokens of generation\). This exploits the asymmetry in reasoning difficulty. The 'LLM-as-a-judge' pattern works because discrimination requires less compute than generation. At $0.60 vs $15.00 per 1M tokens, the ensemble method dominates when the task allows for parallel candidate generation.
