A lot of the video points are plain wrong in numbers and experientially. I don't know how they feel comfortable claiming benchmark numbers didn't improve much from 3.5 to 4
Going off the GP's points alone, they said GPT-3.5T vs. GPT-4, where T I assume stands for "Turbo". If that's the case, then the video must have its timelines wrong - GPT-3.5 Turbo came out with GPT-4 Turbo, which was some time after GPT-4, and OpenAI put a lot of work in making GPT-3.5 Turbo work much better than 3.5. I can sort of buy that someone could find the difference between 3.5 Turbo and 4 to be not that big, but they're making the wrong comparison. The real jump was from 3.5 to 4; 3.5 Turbo came out much later.
