Pick Perplexity if… pick Tavily if… or route both

Pick Perplexity when your queries are cited answer synthesis. Pick Tavily when your queries are RAG (search + scrape + rank in one call). On plain web/news lookups, a cheaper engine usually matches both — so don't hard-code one.

Don't pick one — route to the cheapest that clears your bar.

GroundRoute sends each query to the best-value engine and caches the result. You keep half of what the cache saves you, never more than going direct.
