Remember when comparing Google’s Gemini to ChatGPT just how much faster Gemini was? OpenAI clearly didn’t like that, because GPT-4o is so much faster than GPT-4 ever was that it makes GPT-4 look archaic in comparison. We’ve been testing out GPT-4o for a little while since it launched, and the difference is staggering. As you can see even in the above video, asking GPT-4o to generate a CSV took less than a minute, whereas GPT-4 took nearly as long to just generate the cities being used in the example.
