+Perplexity exposes its Sonar models through an OpenAI-compatible chat
+completions API. Sonar models include built-in web search, which is useful
+for coding agents that need to research up-to-date documentation or APIs
+while answering.
+
+Available models include:

+- `sonar`
+- `sonar-pro`
+- `sonar-reasoning`
