[cost\_intel] Which task categories see >20% gains from reasoning models

Use reasoning models for competition math, formal logic, graduate-level science, competitive programming, and complex multi-step planning. OpenAI's reported benchmarks show AIME 2024 pass@1 of 74.4% for o1 vs 9.3% for GPT-4o; CodeForces percentile 89.0% vs 11.0%; GPQA Diamond 77.3% vs 50.6%. These are the categories where the 10-60x cost premium is routinely justified.

Journey Context:
On knowledge and recall tasks such as MMLU, reasoning models gain only a few percentage points and are not worth the latency/cost. The big wins come from tasks that require search, backtracking, error correction, and planning over many steps. Treat reasoning models as specialists for hard problems, not as a default replacement for instruct models.
