- Choose Perplexity Free: If your usage consists primarily of everyday quick lookups and standard fact-checking.
- Choose Perplexity Pro ($20/mo): If you conduct in-depth engineering research, need access to multiple frontier models (Claude 3.7 Sonnet, DeepSeek R1, GPT-4o) under one subscription, or analyze large codebases and PDFs daily.
- Choose Sonar API: If you are developing customer-facing AI agents, market research bots, or financial intelligence pipelines that require verifiable URL sources.
