Question 1

Should I pick pay as you go or a subscription?

Accepted Answer

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.

Question 2

Does Amux mark up model prices?

Accepted Answer

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.

Question 3

What are credits?

Accepted Answer

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 They can't be withdrawn.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.

Question 4

Can I get an invoice?

Accepted Answer

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