GPT-4 was released in March 2023.

Which means the research that went into it would've been finalised quite some time prior.

Meaning that you're getting close to a 2 year head start.

While they still call it GPT-4, the one topping the rankings are newer iterations of it despite still retaining the same name. The latest one is from 2024-04-09. Sure that one probably finished training a few months ago but it is by no means a 2 year head start.
