There is an NLP section in Jeremy Howard's "Practical Deep Learning for Coders" course (free): https://course.fast.ai/Lessons/lesson4.html

The whole course is fantastic. I recommend it frequently to folks who want to start with DL basics and ramp up quickly to more advanced material.

I took the Deep Learning course [1] by deeplearning.ai in the past, and their resources where incredibly good IMHO. Hence, I would suggest to take a look at their NLP specialization [2].

+1000 to "Neural networks: zero to hero" already mentioned as well.

There's the series this material references - "Neural networks: zero to hero" that has GPT related parts.
