Plans & billing
Plans: a monthly allowance of decisions
A decision is one answered question — a request with three questions uses three. Each decision covers up to 4,000 tokens of state (about 3,000 words); longer states count once more per started block. Your plan's exact allowance, what you have used and a projection are in the console under Billing, and in the x-plan-usage header of every answer.
The allowance renews every month — also on yearly plans. For every full month you stay subscribed it grows by 5 %, up to +50 %. The bonus carries over when you change plans and resets only when you cancel.
Pay as you go: a prepaid balance
Top up from €10 and pay €0.12 per million input tokens; output is free. Billable tokens are the state once plus every question with its options once. Every answer reports your remaining balance in x-balance-remaining (in euros).
Which one pays
| Situation | Paid by |
|---|---|
| Allowance left | the plan |
| Free plan, allowance used up, balance available | the balance, automatically |
| Paid plan, allowance used up, “continue on my balance” on | the balance |
| Paid plan, allowance used up, the option off | nobody — the request is refused with 402 |
The header x-billed-to tells you which one paid for an answer: plan or balance.
