The per-token price never tells the full story. A typical task (1K input + 500 output tokens) on OpenAI o1 costs about $0.0450 — roughly $45.00 per 1,000 runs. But if it needs 3x the tokens of a cheaper model to match quality on YOUR task, the economics flip. The only way to know is to benchmark it on your actual workload.
