Common questions
What do I do when I run out of credits?
Request an upgrade on the Plans page. Upgrades are reviewed by a person, usually within one business day. Once approved the credit quota lands immediately, with no online payment. You can also simply wait for next month's automatic reset.
What does follow-up refinement mean?
After an image is generated you can just describe what to change — "make the sky warmer", say. Nystrel remembers the previous frame and its context, so you never re-describe the whole scene. Each conversation allows up to 20 rounds on the Creator plan.
Do failed generations cost credits?
No. Whether it is a timeout, a content review block, or a queue wait — if nothing was generated, no credits are deducted.
Can I change the aspect ratio mid-conversation?
No. The ratio is chosen on the first generation of a conversation and then locked, because follow-up refinement assumes the composition carries over. Start a new conversation to use a different ratio.
How are my reference images used?
Reference images are used only for that generation, as a basis for the AI to edit or extend. Please make sure you have the rights to any image you upload — no copyrighted works belonging to others, and no images containing other people's likenesses.
