Question 1

Perplexity vs Serper — which is better for AI agents?

Accepted Answer

It depends on the query class. Perplexity is strong at cited answer synthesis; Serper is strong at cheap web and news links. On plain web/news, a cheaper engine often matches both — which is why GroundRoute routes per query instead of betting on one.

Question 2

Is Perplexity or Serper cheaper?

Accepted Answer

$5.00 vs $1.00 on list pricing (verify at publish).

Question 3

Can I use both Perplexity and Serper?

Accepted Answer

Yes — GroundRoute routes each query to whichever clears the quality bar for less, caches repeats, and gives you one schema across both. You keep half the cache savings and never pay more than direct.
