Perplexity Reliability Patterns

Overview

Production reliability patterns for Perplexity Sonar API integrations. Perplexity performs live web searches per request, making response times variable and dependent on search complexity -- unlike static LLM inference.

Prerequisites

• Perplexity API key configured
• Caching layer (Redis recommended)
• Understanding of search-augmented generation latency

Instructions

Step 1: Cache Identical Queries

Perplexity's web search is expensive per call. Cache results for repeated queries within a time window.
