Connection
Default is Asia Pacific (Johor): https://ark.ap-southeast.bytepluses.com/api/v3
The app refuses new jobs that could push you over this. 0 = no limit. Keep the token limits you set in the ModelArk console too — they're the hard stop.
Create it in the BytePlus console: account menu (top right) → API Access Keys. It is a different key from the ModelArk API key above. Needs the free “Premium Creation Benefit Package Entry” (Model activation → Advanced Creation Rights).
Team
Everyone signs in with their own account. Editors can generate and download, but can't see keys or settings. Budget 0 = no personal limit (the overall budget above still applies).
Characters (asset library)
Characters registered in the ModelArk asset library. Paste the asset ID (not the group ID), with or without asset://. They appear under “Add a saved character” and in every Library picker.
“Sync from BytePlus” pulls in every character in your asset library, including ones you uploaded in the console, with their pictures.
Models & prices
Copy each Model ID exactly from the ModelArk console (Model activation → Model details). Prices are USD per million tokens (video) or per image, from the console; adjust if yours differ.
