Understand AI token usage and cost.

AI models process text in tokens, which are pieces of words. About 100 English words is roughly 133 tokens, though the exact amount varies by model and tokenizer. You pay for input sent to the model and output it writes back; repeated conversation context can be billed again. That is metered API usage, not a flat consumer subscription.

Technically they charge by the token, a chunk of a word, about three quarters of one. 100 words is roughly 133 tokens. That's the only jargon you need today.
