Good to know

What is Grade?

One word in the model name. Add it and that request is billed at half of list.

Is it the exact model I name?

When the vault is funded, yes: the vault pays the other half. Otherwise a model matched to the one you name answers. Batch always runs the exact model.

What if a request fails?

It is free. Errors, timeouts and empty answers are never charged.

Can I pay more than list?

No. The list price is a ceiling on every request.

How do I pay?

USDG from your wallet. 1 USDG is $1 of usage. No fee, no subscription.

What does the token do?

Stakers get half price on every model and a daily rebate. Part of Bestex's margin on every paid request is also set aside to buy $BESTEX for stakers. Each buy is listed on the Stake page.

Do you keep my prompts?

No. Only billing data: model asked for, tokens, cost, time.
