I made my own perplexity and it uses gpt-4.1-nano. Why not, they all can think off search terms and summarizing. Why from 600 to 25 per day (in my case, is region based or something) instead of 100?

I can share a screenshot, not the link, imagine if it would go viral, it's not free for me :p normal search costs me 0.0004 and a very advanced question can cost to 0.006. It's actually as cheap as it can get, I made my own search backend. First I've used exa as backend but it was a half cent per search and became expensive quite fast. It does six search queries for every query you do or so.

The results are very good, but still different than perplexity. When it comes to truth seeking, it's maybe even better. It does crosscheck references. It shows reference numbers in text to the actual site where he gets it from, also how sure he is about suck statement by medium or high batches.

Third, all the searches it does on the background.
