This connects Claude to Perplexity's Sonar models through OpenRouter for live research queries. It automatically picks between Sonar Pro Search for quick lookups and Sonar Reasoning Pro for analytical work based on keywords like "compare" or "analyze" in your query. Useful when you need recent papers, statistics, or protocol details with citations rather than Claude's training data cutoff. The model selection logic is transparent, scoring queries on complexity indicators like reasoning keywords and question count. One thing to note is it requires an OpenRouter API key and credits, so factor that into your workflow if you're doing heavy research sessions.
