1/ So I spent a day trying to understand GPT-3: what it is and how it works, from the pov of a layperson.
Compiling my learnings here.
Hope it helps a few to get a basic understanding of GPT-3 and how it works.
It's time for a
GPT-3 MEGATHREAD!

2/ Disclaimers:
I've dabbled with basic linear/logistic regression and Bayesian models earlier in my career. My knowledge is still pretty amateurish, and this thread isn't meant to be *precise* as much as its meant to layperson-friendly peek into the blackbox that's GPT-3.

3/ Having said that, if you find any grievious mistakes, please reply to the thread and I'll add the corrections to the thread.

4/ To start off with, let's see how any deep learning ML model "learns."
5/ There are essentially two components to a machine learning model: PARAMETERS and DATA.
The model identifies a set of PARAMETERS that help it to identify and predict the nature of any given data. It learns these parameters this using the DATA it is trained on.

6/ A analogy, we identify a cat by using parameters like
does it have the shape of a cat?
features of a cat?
color of a cat?
do others call it a cat?
etc.
And we can do this based on our training dataset — what we already know about cats from our past.

7/ For most of us, that would be something we learned as kids:
that this is a cat and this isn't a cat.
We often don't feel this parametric-reasoning happening everytime we see a cat because it happens subconsciously, in realtime.
