Visual intro to Transformers by 3Blue1Brown’

Introduction:
In the rapidly evolving field of artificial intelligence, understanding the inner workings of Large Language Models (LLMs) like GPT (Generative Pre-trained Transformers) is essential for both developers and enthusiasts. This blog post highlights three insightful videos that break down core concepts behind these models: the fundamentals of transformers, the critical role of attention mechanisms, and how LLMs store and retrieve facts. These videos by 3Blue1Brow provide a visual and accessible way to grasp the complex processes that power today’s most advanced AI systems, offering valuable insights into their design, functionality, and potential applications.

But what is a GPT? Visual intro to transformers 

This video provides a clear, visual introduction to the concept of Generative Pre-trained Transformers (GPTs) and how they revolutionized natural language processing. It explains the foundational concepts of transformers, including tokenization, self-attention, and the overall architecture that allows these models to understand and generate human-like text.
Importance: Understanding GPTs is crucial for anyone interested in AI and NLP as they form the backbone of today’s most powerful language models.

Attention in transformers, visually explained 

This video dives deeper into the “attention” mechanism that is central to the power of transformers. It breaks down how attention works, how it helps the model focus on different parts of an input sequence, and why it is essential for handling complex language tasks.
Importance: Attention mechanisms are key to improving model performance and efficiency, making this concept fundamental for developing more advanced AI systems.

How might LLMs store facts

This video explores how Large Language Models (LLMs) like GPTs store and retrieve information or “facts.” It discusses the underlying mechanisms by which LLMs encode knowledge and how they can generate responses based on their training data.
Importance: Understanding how LLMs store and use information is vital for improving their factual accuracy and reliability in real-world applications.
