How to explain LLM architecture to your mom and dad

The article explains that a modern large language model like GPT-3 is built from 577 spreadsheets—tensors—containing about 175 billion parameters. It describes the first spreadsheet as a dictionary mapping words to numbers and notes the fixed size of 50,257 rows by 12,288 columns, with the other 576 layers following a repeating pattern, all of which drive the model’s outputs. It also discusses how, despite being labeled a black box, researchers can inspect internal structure and that understanding these internals is considered important for safety and responsible AI development.
