How Transformers Power AI- A Short Guide to LLMs, GPT, and ChatGPT

Описание: The YouTube video "AI: The Transformers," explains the core components and functionality of Transformer neural networks, which are fundamental to modern AI advancements like Large Language Models (LLMs) such as ChatGPT. It details how GPT (Generative Pretrained Transformer) models work, focusing on text generation through repeated prediction and sampling of subsequent tokens. The video further describes the architectural steps within a Transformer, including tokenization, embedding words into high-dimensional vectors that capture semantic meaning, and the role of attention blocks and multi-layer perceptrons in refining these embeddings to incorporate context. Finally, it touches on the unembedding process and the softmax function used to generate probability distributions for the next predicted token, highlighting how temperature parameters can influence the creativity of the generated output.
