The Speed fun-facts page has a live exhibit just below its cards. A short answer streams onto the screen one token at a time, each token a colored chip of text. Below it are four buttons, from human reading pace up to a specialised chip.

Try these three, slowest first:

• Human reading. About 5 tokens a second, roughly how fast you read silently.
• Cloud model. About 80 tokens a second, typical for a large model in the cloud. Notice it is already far ahead of your eyes.
• The fastest button. The answer lands almost at once.

Then read the cards above it. Look for the one that explains the speed limit: each new token means reading all the weights from memory. Next, find the card where 4-bit weights raise that limit four times. Finish with the quiz card about serving many chats at once. It shows how one chip keeps many people’s replies flowing at once.
