What are the limitations of GPT-4?

- [Instructor] Although GPT-4 performs very well, it has some flaws. There are at least three areas that need some work. Firstly, you cannot fine-tune the GPT-4 models, and GPT-4 doesn't update its knowledge in real time. It was trained with the data up to September, 2021, so it has no knowledge of anything that has happened since. And finally, sometimes it makes up facts. Now, if a model like GPT-4 performs so well, why would you want to fine tune these models? Well, let's say you were working in a very niche area like academic medical papers for infectious diseases. I've picked a random paper from the Journal of Infectious Diseases. Go ahead and pause this video, and try and read just the title of this paper and make sense of it. This clearly isn't everyday English, and there's going to be very specific terminology used in this medical field. It's unlikely that the GPT-4 model has been trained on a dat set that includes…
