That one website that shows how ChatGPT-style AI works on the inside

Why it's the pick

Type a sentence and watch a real GPT-2 model, running in your browser, split it into tokens, decide which words matter and pick the next one, with a temperature slider to play with. It's made by Georgia Tech researchers and uses an older, small model, so it shows the mechanics rather than what today's chatbots can do.
