Everything GPT-2: 0. Intro

Why GPT-2?

What is Generative Pre-trained Transformer (GPT)-2?
GPT-2 is a state-of-the-art machine learning architecture for Natural Language Processing (NLP) released by OpenAI in 2019.

OpenAI just released GPT-3 as an API for a closed beta and has committed to public release by the end of 2020. So why bother with its predecessor, GPT-2?
The current closed beta prevents everyone but Silicon Valley insiders, well-known internet bloggers, and published researchers from accessing GPT-3. Based on the manner of release for GPT-3, OpenAI will probably never release the core code. Unlike with GPT-3, OpenAI has open sourced the full model for GPT-2.

How much of what you learn about GPT-2 will apply to GPT-3?
Almost everything. The architecture for GPT-3 is a scaled-up GPT-2. All the underlying design theory remains the same.

Why should you continue reading?
Over the past three months, I have read everything I can find about GPT-2. I am going to provide you with a comprehensive overview. I will point you to the best existing resources and create new ones where necessary. All you have to do is read, think until your brain hurts, take a break, and repeat. I will use Google Colab Notebooks so you can learn by running the code.

(aside) OpenAI does not seem so open.
Indeed. They just sold Microsoft the exclusive rights to GPT-3. Let’s go down the rabbit hole. Who has funded OpenAI to the tune of over 1 billion dollars? Microsoft. To balance my bias, a perspective from VOX. Something seems amuck but the study of nepotism, big business concerns, and tech monopolies will have to wait for another blog series.
