The Simplest Way to Understand How LLMs Actually Work!
SMRTR summary
Every word in a sentence is essentially having a conversation with every other word, and that's the revolutionary breakthrough powering today's artificial intelligence systems. Transformers, the technology behind ChatGPT and other language models, work by giving each word three different roles: a query asking "what information am I looking for?", a key announcing "what information can I provide?", and a value containing its actual meaning.
When processing a simple question like "What is the capital of France?", the word "capital" searches for relevant context and discovers a strong connection to "France" while largely ignoring words like "what" or "is." This happens simultaneously across multiple attention mechanisms, like several people reading the same sentence but focusing on different patterns.
Unlike older computer models that plodded through text one word at a time, transformers examine entire sentences at once, allowing distant words to influence each other's meaning. This parallel processing, combined with multiple layers of analysis, enables machines to understand language with unprecedented sophistication, transforming how computers comprehend and generate human communication.
