I've been thinking how Sydney can be so different from ChatGPT. Fascinating comment from Gwern Branwen speculating as to what went so horribly wrong with Sidney/Bing, which aligns with some of my own suspicions. Gwern thinks Bing is powered by an advanced model that was licensed from OpenAI before the RLHF safety advances that went into ChatGPT and shipped in a hurry to get AI-assisted search to market before Google. “What if Sydney wasn’t trained on OA RLHF at all, because OA wouldn’t share the crown jewels of years of user feedback and its very expensive hired freelance programmers & whatnot generating data to train on?”
