How AI requests are billed by token, with cache prices and the monthly budget.

By token

Section titled “By token”

We bill all models by token, also the models that run on our own hardware. Prices are in Models and prices.

The token counts come from the usage field of each answer.

Cached prompt tokens

Section titled “Cached prompt tokens”

Some models cache the start of a prompt. Cached tokens bill at the cache read price, not the input price. Tokens written to the cache bill at the cache write price.

cost = (prompt_tokens - cached_tokens - cache_write_tokens) × input price
     + cached_tokens × cache read price
     + cache_write_tokens × cache write price
     + completion_tokens × output price

prompt_tokens includes cached_tokens and cache_write_tokens. They are in usage.prompt_tokens_details. Prices are for each 1M tokens.

Requests with no usage

Section titled “Requests with no usage”

A request with no usage in the answer bills nothing.

Budgets

Section titled “Budgets”
Budget Period
Account $5 for each calendar month (UTC). All keys together. It resets on the 1st of the month at 00:00 UTC.
Key You set it. It counts the total spend of the key, for all time.

When a budget is spent, requests fail with 402 budget_exceeded. Requests that started before can complete, so the spend can go a little over the budget.

See your spend

Section titled “See your spend”
  • Console: the AI tab shows the spend for each key.
  • API: GET /v1/projects/{project_id}/usage returns ai_spend_usd for this month.
