[cost\_intel] Which hard STEM / math tasks justify a reasoning model?

Use reasoning models \(o3, o1, DeepSeek-R1\) for competition-level math, advanced physics/chemistry derivations, and novel research-grade problems. They solve AIME-level problems at 80-97% vs ~13-40% for fast instruct models. For routine arithmetic, one-line formulas, or calculator-style computations, use an instruct model plus a tool.

Journey Context:
Benchmarks like AIME 2024, GPQA Diamond, and FrontierMath show the clearest reasoning-model advantage. DeepSeek-R1 scores 79.8% on AIME 2024 and 71.5% on GPQA Diamond vs GPT-4o's 13% and 49.9% respectively; o3 reaches 96.7% / 87.7%. These tasks have verifiable answers and long solution horizons, so extra thinking tokens translate directly into accuracy. The signature that you need a reasoning model: the instruct model produces plausible-looking but wrong multi-step derivations, or its accuracy plateaus below your threshold despite few-shot prompting. The cost gap is 10-100x, so treat it like a specialist consult, not a default.
