I'm super happy that these types of deep research applications are being released because it seems like such an obvious use case for LLMs.

I ran Perplexity through some of my test queries for these.

One query that it choked hard on was, "List the college majors of all of the Fortune 100 CEOs"

OpenAI and Gemini both handle this somewhat gracefully producing a table of results (though it takes a few follow ups to get a correct list). Perplexity just kind of rambles generally about the topic.

There are other examples I can give of similar failures.

Seems like generally it's good at summarizing a single question (Who are the current Fortune 100 CEOs) but as soon as you need to then look up a second list of data and marry the results it kind of falls apart.
