Verdict
Pros
  • Real-time web search overcomes the training data cutoff limitation for current information
  • OpenAI-compatible API enables straightforward integration for existing OpenAI users
  • Cited sources improve answer verifiability for research applications
  • $1/1000 requests is accessible for development and moderate-traffic production
  • Integrated real-time search with LLM reasoning reduces engineering complexity of search-augmented AI pipelines
  • Entry pricing from $5/1M tokens accessible for developer experimentation and early-stage products
  • Consumer product validation at scale provides confidence in underlying search-LLM integration quality
  • Citation tracking provides source attribution required for trustworthy AI-generated responses
Cons
  • Real-time search adds latency compared to direct LLM inference
  • Search quality depends on Perplexity's web indexing coverage
  • More expensive than direct LLM inference for applications without current information needs
  • API ecosystem maturity is growing but less developed than established providers like OpenAI
  • Online model web search adds latency — not suitable for millisecond-sensitive applications
  • Competing with Bing AI Search API, Brave Search API, and custom search-augmented LLM pipelines
