Well, I've spent two days and half scouring PAI for models. It would seem that most models are prevented from downloading, which is kind of a dick move.
Furthermore, the website itself is either trying to mine crypto when opened or has some faulty scripts in it causing memory leaks. I had the misfortune of leaving a Firefox page open for one night. I woke up to the sound of my PC spinning its coolers at maximum. When I opened the Task manager, I've witnessed a Firefox process consuming 38 gigabytes of RAM for the first time in my entire life.

So yeah. Fuck PixAI.
