The per-token price never tells the full story. A typical task (1K input + 500 output tokens) on Sonar Reasoning Pro costs about $0.0060 — roughly $6.00 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.

What that means in practice

1x One typical task (1K input + 500 output tokens): $0.0060
1K 1,000 runs of that task: $6.00
💡 Real cost depends on how verbose the model is on YOUR prompts — benchmark to measure actual tokens, not estimates.
