What is the credit policy for workflow?
A workflow consists of several single steps. Each step costs 0.2 credit when processing an image, and downloading the final result generated by workflow will cost 1 credit.
For example, if you created a 5-step workflow, then processing the image and downloading the final output will cost 2 credits in total (0.2x5+1).
Without Workflow, processing one image with 5 features and downloading the final result will spend 6 credits in total. That is why workflow not only improves work efficiency by simplifying your work procedure, but also saves credits to a great degree.
