[cost\_intel] When do reasoning models justify 10x cost for math tasks?

Use o3/o1 for AIME/AMC/Olympiad problems where accuracy >90% is required; use GPT-4o/Claude 3.5 Sonnet for standard engineering math where ~70% accuracy suffices and latency matters.

Journey Context:
On AIME 2024, o1-preview scored 83% vs GPT-4o's 13%. The cost is roughly $15-30 per million tokens vs $2.50 for 4o—a 6-12x premium. For competition math, there is no viable alternative; however, for 'calculate the standard deviation of this dataset' tasks, instruct models produce identical outputs at 1/10th the cost and 10x the speed. The breakpoint is task rarity: standardized test problems need reasoning, calculator-style problems do not.
