Frequently asked questions

For production workloads and commercial products, pay as you go: no extra quota limits, cost scales linearly with usage, and every dollar is attributable down to the token. For individual development, learning or exploration, a subscription will be simpler once it ships — a flat fee, no per-call accounting. Subscriptions aren't live yet, so everyone is on pay as you go today.

No. Inference settles at the provider's own list price, we add nothing on top, and top-ups carry no fee. Our revenue comes from the gap between the wholesale discount we negotiate upstream and the discount we pass on to you.

Credits are prepaid balance on your account, used only to pay for inference. They can't be withdrawn. Top-ups land immediately and are drawn down by actual usage.

Yes. Every successful top-up produces a receipt, viewable and downloadable from the billing page in your console.
