[cost\_intel] Assuming reasoning models always outperform on math/coding

Deploy o3/o1 only for competition-level math $AIME/USACO$ or >100 line code generation; use GPT-4o/Claude 3.5 Sonnet for LeetCode easy/medium and debugging

Journey Context:
Reasoning models show 50%\+ accuracy gains on AIME $o1: 83% vs GPT-4o: 13%$ but only 3-5% on standard coding interviews. The cost-per-correct-answer for LeetCode easy is $0.02 $instruct$ vs $0.40 $reasoning$. Worse, o1 occasionally overcomplicates simple array problems with unnecessary abstraction layers due to over-optimization for competition problems. The cliff: when problem difficulty drops below USACO silver, reasoning effort yields negative ROI.
