What is a token?

A token is the basic unit of text that the model processes. Tokens are not the same as characters or words — they are text fragments determined by the model’s own tokenizer.
Text ExampleApprox. CharactersApprox. Tokens
English word4–5 characters~1 token
Chinese character1 character~1.5–2 tokens
1,000-word English article~5,000 characters~750 tokens
1,000-character Chinese article~1,000 characters~1,500–2,000 tokens
These are estimates. Different providers such as OpenAI, Google, and Anthropic have slightly different token calculation rules.

Token Types and Billing Rules (Claude Opus 4.7)

Input Tokens (Prompt) — $5.5 / million

Everything you send to the model — system prompt, conversation history, user messages, uploaded documents — all counts as input tokens.

Output Tokens (Completion) — $27.5 / million

The text the model generates in response. Output tokens cost 5× more than input tokens, so keeping responses concise has a meaningful impact on cost.

Cached Tokens — Billed at 0.25× input rate

Prompt content served from cache is charged at only 25% of the normal price. Useful for long system prompts or repeated context, and can significantly reduce costs.
