> GPT is great until you realize 50% of its output is a totally manufactured confabulation with zero connection to reality.<p>GPT-4 might not be as smart as people but it's performing as well as humans on many kinds of AP tests, medical certification tests, bar exams, SATs, GREs, etc. You can see it on the tech report and the sparks of agi papers. I guess the author thinks those tests are bad, or he didn't read about those results, or he thinks those papers lied about the results, or he is being willfully misleading, I don't know which one.<p>I don't know of the author (maybe he is famous or not idk) but it looks like maybe he is promoting some competitor to GPTs "I’m proposing a new machine learning meta-architecture for learning forward models. The architecture is called Predictive Vision Model (PVM)."
