Perplexity Sonar is the developer API version of Perplexity's search-grounded AI, allowing developers to build applications that need current information rather than being limited by training data cutoffs. For applications where accuracy on current events, prices, news, or recent data matters, Sonar provides up-to-date answers with web citations. The API uses an OpenAI-compatible interface, making migration from OpenAI straightforward. The key capability difference is that Sonar searches the web in real time before generating a response. Common use cases include financial data queries, news summaries, product comparison research, and any application where the answer changes frequently.
Perplexity Sonar API runs as ai search software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api, with API access for teams that want to embed it into their own products.
