/ FAQ

Lumen Image XL · FAQ

Does changing the prompt change the sample picture?

No. Demo assets are fixed illustrations. Loading a prompt explores the form and request structure, not live image quality.

Can I generate real media here today?

No. These are fictional preview models. The isolated demo returns fixed sample assets and does not call a provider or change your real balance.

Does trying the page cost credits?

This demo does not charge real credits. A free allowance for future live calls has not been announced.

What does official fallback do?

It is off by default. The demo can illustrate a second channel; live fallback needs compatible inputs, an approved quote and a verified provider integration.

Can I use outputs commercially?

Check the terms of the specific model and the rights to all source material. This template makes no blanket commercial-use promise.
