“Short chat” = 2,000 input tokens + 500 output tokens. Checkout runs on Stripe; we never see your card. No key yet? We’ll create one for you at checkout — save it, your credit lives on it.

Compare the packs

Mini, Maker and Studio all buy credit at the same rate — $1 buys $1 of usage. Bigger packs just mean fewer top-ups. Founding is the exception: a one-time offer that doubles your credit.

How billing works

Zero markup

Every model is billed at the price the provider charges us. If the provider reports a higher actual cost for a call (images, web search, audio), that exact cost is what’s debited — never more.

No subscriptions, no seats, no monthly minimums. Unused credit stays on your key.

Input and output priced separately

Models charge different rates for what you send (input) and what they write (output), per million tokens:

cost = input tokens × input price + output tokens × output price

You see the exact debit for every call on your account.

Real prices, a few examples

USD per 1 million tokens, straight from our live price list. Prices follow the provider and can change.
