Perplexity Cost Tuning

Overview

Reduce Perplexity Sonar API costs. Perplexity charges per-token (input + output) plus a per-request fee that varies by search context size. The biggest cost lever is model selection: sonar-pro costs 3-15x more than sonar per request.

Pricing Reference

Model	Input $/M tokens	Output $/M tokens	Request Fee
sonar	$1	$1	$5 per 1K requests
sonar-pro	$3	$15	$5 per 1K requests
sonar-reasoning-pro	$3	$15	$5 per 1K requests
sonar-deep-research	$2	$8	$5 per 1K searches

Search context size (Low/Medium/High) affects the request fee. More context = higher fee.

Prerequisites

• Perplexity API account with usage dashboard
• Understanding of query patterns in your application
• Cache infrastructure for search results

Instructions

Step 1: Route Queries to the Right Model

// 60-70% of queries can use sonar, saving 3-15x per query
function selectModel(query: string): "sonar" | "sonar-pro" {
  const simplePatterns = [
    /^what is/i, /^define/i, /^who is/i, /^when did/i,
    /current price/i, /^how many/i, /^is it true/i,
  ];
  if (simplePatterns.some((p) => p.test(query))) return ;

   complexPatterns = [
    , , ,
    , , ,
  ];
   (complexPatterns.( p.(query)))  ;

   ; 
}
