FAQ
What is DuoMoHui?
DuoMoHui is a multi-model AI image generation website: enter a prompt once and get a version from each of four models — Jimeng, GPT Image, Gemini, and Kling — at the same time, making it easy to compare different styles, with continuous refinement across multi-turn conversations.
How many credits does one generation use?
Each image uses 1 credit. Running N models at once uses N credits (1 per image). Exception: the free first round — 1 image per model in that round is completely free.
Do failed generations consume credits?
Failed paid generations are automatically refunded. If all models fail in the free first round, that free round is refunded for retry.
How many free credits do I get?
New users get 1 free round on sign-up (1 image per selected model in that round). Free credits are tied to your account, so please avoid temporary emails to prevent issues.
Do the packs expire?
Yes. Paid credits are valid for 180 days from the purchase date — please use them within that period.
How do I refine across multiple turns?
Tap "Keep editing from this image" under any generated image, and this round will only let that model refine from that image.
How do I specify an aspect ratio?
Write "vertical / phone wallpaper / 16:9 / 1:1" and similar terms in your prompt, and the system will detect and adapt them to each model automatically.
Are refunds supported?
Virtual credits are non-refundable once successfully used. Unused paid credits can be used before they expire, subject to the Terms of Service.
How long are my works kept?
Works created with free credits are kept for 21 days, and those created with paid credits for 180 days; they are cleaned up automatically after that. We recommend downloading anything you want to keep.
Can I download or delete my works?
Yes. Open any work to find a Download button in the large view; the button at the top-right of each thumbnail deletes it. Deleted images are removed from our servers immediately and cannot be recovered.
