Differences between GPT-4 and GPT-3 and their training data

GPT-4 is compared to GPT-3, highlighting the difference in scale. GPT-3 is trained on data from the internet, but this can include unreliable information. GPT-4, however, has no specialized medical training but is able to accurately summarize and analyze medical research papers. It can even speculate on the effectiveness of drugs for different genetic mutations. Despite being trained on the common crawl, GPT-4 performs impressively in scientific tasks.
