The per-token price never tells the full story. A typical task (1K input + 500 output tokens) on Grok 3 Mini costs about $0.0005 — roughly $0.55 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.
