Web-grounded reasoning model for multi-step research and cited answers
Perplexity Sonar Reasoning is currently listed from a single provider. Its reference price is $1.00 per 1M input tokens and $5.00 per 1M output tokens.
Artificial Analysis rates it 8.7 on the Intelligence Index. Against its lowest blended price of $2.00 per 1M, that is roughly 4 index points per dollar, which is the value ratio the leaderboards rank on.
The context window is 127,000 tokens, with an output limit of 4,096 tokens. It supports reasoning. Its training knowledge cuts off at 2025-01.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
