It is a bit worrying to hear that Deep research still spews out hallucinations. I wonder if the Perplexity Deep Research has a double check reasoning function...? If so, it would seem to still fall prey to the stochastic whims of LLMs.

In your experience, does Gemini's Deep Research also hallucinate? I haven't give it a real test drive yet.

And since you have played around with both, do you have a sense of the level of quality of the sources they draw on and cite?

I remember about a year ago playing with Perplexity to do some initial research ... it gave me subreddits and even a LinkedIn article I wrote! I was hoping for more higher quality and vetted sources.

I haven't seen the hallucination problem with Gemini's Deep Research, but I need to check more carefully. Overall, I'm pretty impressed with Gemini's Deep Research, although I use it primarily for background info rather than for specific citations. With Perplexity, I almost always limit the search to academic sources. Before the deep research debacle, Perplexity has been pretty solid. Hopefully, it will improve soon.
