How Does ChatGPT Work?

ChatGPT works by predicting the next word in a sequence, enabling it to generate coherent and contextually relevant responses. It has been trained on a diverse dataset comprising text from the internet, books, and other sources up to its knowledge cutoff in October 2023. The model uses attention mechanisms to weigh the importance of different words in the input, allowing it to understand context and generate meaningful replies. During inference, it processes the input text, encodes it into numerical representations, and then decodes it to produce a response.
