Pick Exa if… pick Tavily if… or route both
Pick Exa when your queries are academic, semantic, and page-content retrieval. 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.
