Editorial note

Perplexity is an answer engine rather than a model maker: as of September 2026, the paid Pro tier lets you choose between third-party models from labs such as OpenAI, Google and Anthropic and adds Deep Research, while the much pricier Max tier raises the limits. Its strength is that answers arrive with sources you can open and check, and developers get web-grounded, cited answers through the Agent API. The trade-off is dependence on other labs' models and on what the web returns; where no good public source exists, a citation does not make an answer correct.
