Perplexity says its Deep Research “excels at a range of expert-level tasks — from finance and marketing to product research” and takes about 2-4 minutes to come up with an answer, during which it “performs dozens of searches, reads hundreds of sources, and reasons through the material.” Once finished, its reports can be shared or exported as a PDF. The company claims it outperforms competitors — like OpenAI’s o3-mini and o1, and DeepSeek-R1 — on the Humanity’s Last Exam benchmark, earning a 21.1 percent accuracy score (though this is lower than OpenAI’s Deep Research scored).
Free users will be limited to five queries per day, while Pro subscribers will get 500, according to a tweet from the company.
