No winner has been declared. Run Perplexity Search API and Exa Search API against the same frozen task and publish the raw scores before recommending either one.
Has WhichAI declared which product is better for AI research?
No. This page records narrowly sourced vendor facts and a test protocol. WhichAI has not run both products on the same frozen task, so there is no published winner.

| Decision question | Does Perplexity Search API produce the accepted output with fewer corrections, lower observed cost, or a better control fit on your frozen task? | Does Exa Search API produce the accepted output with fewer corrections, lower observed cost, or a better control fit on your frozen task? |
Freeze one task, its inputs, acceptance criteria, account state, model settings, and evaluator before the first run. Use the same number of trials for both products.
Declare a winner only when the run and a predeclared decision rule are published. A tie or a split decision by task is valid.
