What are tokens?
Tokens are the units AI uses to measure text. One token is roughly 3/4 of a word. So 1M tokens translates to about 750,000 words, or 1,500 pages of text. In practical terms, that means you can paste an entire textbook, a full codebase, or a dozen research papers into a single conversation.
