Top up
Open Billing. The amount you type is the dollars you send.
Balance is dollars. Tokens are what those dollars buy
The account ledger is USD. Each request deducts dollars at the live rate. Beside it, Tokens today lists that dollar balance at each model's list price. The counts move when prices move, even if you have not spent anything, and they can differ by model.
Where the x2 shows up
GNK is an x2 bonus. Pay with GNK (native) or WGNK (wrapped) and the dollars you type buy twice the tokens of card or other crypto.
The bonus lands with that top-up. It is not a cheaper rate later.
On the top-up page, the two cards are the check: same dollars in, and the GNK / WGNK card shows the x2. WGNK quotes include a small network-fee buffer so the transfer still covers the intended USD.
Rate / 1M is not the bonus
On the dashboard, List is today's published price per million tokens. Charged is what was actually deducted. They can differ when a request is billed from an estimate, or when the Gonka price moved.
Neither number includes the GNK x2 bonus. The bonus was the extra tokens from that top-up. You will not see a separate "50% off" on Rate / 1M.
Free grant
New accounts start with 1,000,000 tokens. That grant is usage, not a USD wallet. After it is gone, completions need a USD balance.
When credit lands
On-chain GNK/WGNK credits after the deposit is seen. Card / other crypto credits after the invoice is confirmed. You can leave the page — the credit still applies.
