How ChatGPT is trained using a large dataset of text from the internet

ChatGPT is not a model trained from scratch but rather a refined version of GPT-3.5, which itself was a refined version of GPT-3. GPT-3 trained the initial model on a massive collection of internet-sourced data (570 gigabytes of text and 175 billion parameters), including material from Wikipedia, Twitter, and Reddit.

How ChatGPT is trained

So, if you input "write a poem about nature in the style of Rimbaud" into the ChatGPT website, it will produce a poem that closely resembles the work of Arthur Rimbaud. This is because the model has examples of Rombaud’s work in its storage. Let’s break it into more simple ideas. If you read an entire book about what IT is and what fields incorporate IT into their businesses, you are more likely to answer every single question others ask you. The brain stores and processes the information you read.

There is, however, a subtle distinction. You may read a few hundred books in a lifetime, but ChatGPT has devoured the internet's worth of material. That massive collection includes all sorts of data, including poetry by Arthur Rimbaud. Naturally, this chatbot has gone over each poem and found patterns in them.
