In this course, you will learn how large language models work, what they are capable of, and where they are best applied. You will start with an introduction to LLM fundamentals, covering core components, basic architecture, model types, capabilities, limitations, and ethical considerations. You will then explore the inference and training journeys of LLMs. This includes how text is processed through tokenization, embeddings, positional encodings, and attention to produce outputs, as well as how models are trained for next-token prediction at scale. Finally, you will learn how to build with LLMs using a developer-focused toolkit. Topics include prompting, embeddings for semantic search, retrieval-augmented generation (RAG), tool and function calling, evaluation, and production considerations. By the end of this course, you will understand how LLMs actually work and apply them effectively in language-focused applications.

Frequently Asked Questions

What is the basic of LLM?

The basics of LLMs include understanding neural networks, transformers, large datasets, and the processes of pre-training and fine-tuning to enable the model to generate human-like text.

Is GPT an LLM?

Yes, GPT (Generative Pre-trained Transformer) is a type of LLM developed by OpenAI, known for its ability to generate coherent and contextually relevant text based on the input it receives.

What is the difference between LLM and AI?

AI (Artificial Intelligence) is a broad field encompassing the creation of intelligent systems, while LLM (Large Language Model) is a specific type of AI focused on understanding and generating human language; LLMs are a subset or tool within the broader field of AI.

What does LLM include?

LLMs include neural networks with millions or billions of parameters, trained on vast datasets of text, and include components for tokenization, embedding, attention mechanisms, and output generation to process and generate human-like language.
