Sonar Reasoning Pro
Pricing & Specs
Perplexity · $2 input / $8 output per 1M tokens · 128K context window
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.
