BytePlus Model Services are not available in the United States. If you are in the US, do not open an ARK account for this. Use a fal or evolink key and pick Seedance there.
Outside the US, the key is created in the ModelArk console under API Key management, in the lower-left menu. Do not share the key.
Seedance 2.5, Seedance 2.0, Seedance 2.0 mini, and Seedance 2.0 fast will not run until the model is activated. Activation needs one of these: BytePlus Credits of at least USD 30 on a verified account, an AI Savings Plan of USD 30 or more with balance left, or model resource packs of USD 30 or more with quota left. BytePlus Credits are BytePlus’s balance, not a lotgen balance. Then open the model on the activation page. Seedream stills use this same key and have to be switched on too.
