When the Problem Is Genuinely Hard, This Is the Reasoning Model to Reach For
“OpenAI o1 trades speed for depth — it thinks before it answers, and on hard maths, science, and multi-step coding it lands answers other models miss.”

✓ ProsMarkedly stronger on hard reasoning, maths, and science. Reliable on multi-step problems where chat models guess. Excellent for complex debugging and proofs. Clear step-change in accuracy on difficult tasks.
✗ ConsSlow — the reasoning pass adds real latency. Expensive per query. Overkill (and wasteful) for everyday tasks.
