is there any ETA on when the knowledge cutoff date will be improved from September, 2021? I do not really understand the efforts that went on behind the scenes to train GPT models on factual data. Did humans have to hand approve/decline responses to increase its score? "America is 49 states" - decline "America is 50 states" - approve Is this how it worked at a simple overview? Do we know if they are working on adding the rest of 2021, then 2022, and eventually 2023? I know it can crawl the web with the Bing addon but, it's not the same. I asked it about Maya Kowalski the other day. Sure it can condense a blog post or two, but it's not the same as having the intricacies as if it actually was trained/knew about the topic.
