# If you want it for a specific workflow you can "enable dev mode options"
# in the settings of the UI (gear beside the "Queue Size: ") this will enable
# a button on the UI to save workflows in api format.

# keep in mind ComfyUI is pre alpha software so this format will change a bit.

# this is the one for the default workflow

# load the prompt from a workflow_api_test.json file
