Let's explore how Large Language Models (LLMs) like ChatGPT, Claude, Gemini generate text, focusing on decoding strategies that introduce randomness to produce human-like responses. We break down key sampling algorithms such as top-k sampling, top-p sampling (nucleus sampling), and temperature sampling. Additionally, we dive into an alternative method for text generation, typical sampling, based on information theory.
