[cost\_intel] When does paying 50x for o3-mini vs GPT-4o-mini actually improve math accuracy?

Use reasoning models only when the math requires >2 step symbolic manipulation or novel proof construction; for template-based calculation, instruct models with tool-use \(Python\) are 10x cheaper with equal accuracy.

Journey Context:
People assume 'math = reasoning = expensive model'. But competition math \(AIME/AMC\) shows 60% accuracy gaps between o1 and GPT-4o, while grade-school word problems show <5% gaps. The cliff is at 'novel algorithm design' vs 'executing known algorithms'. Using o3 for 'what is 234\*567' is waste; using it for 'prove this inequality with no obvious AM-GM path' is essential.
