When to use it

• Use it when you want grounded, up-to-date answers with citations instead of the model's stale training data.
• Use it when you need a quick ranked list of web results to feed into an agent (perplexity_search).
• Use it when you need a long, sourced research report on a topic (perplexity_research / sonar-deep-research).
• Use it when a task needs structured multi-step reasoning rather than a simple lookup (perplexity_reason).
• Use it when you want to strip chain-of-thought tags from responses to save context tokens (strip_thinking).

4. 4Optionally configure PERPLEXITY_TIMEOUT_MS and PERPLEXITY_PROXY for long research calls or corporate networks.
