I decided to give perplexity another try a few days ago, and it still seems to hallucinate things. Given the same exact tasks/prompts both Claude and Chatgpt got the facts correct.

Perplexity uses those same models without "deep research" on, don't see how the result would be any different. I haven't gotten have any problem with it. Claude should be good but they rate limit too much their desktop and site it's almost unusable every time I tried.
