Questions
Generation is asynchronous
A generation call returns an id, not an image. Poll the generation until it completes — a flow step that sleeps and re-reads is the usual shape.
Generating costs tokens
Every image draws on your API token balance, which is separate from the web app's credits.
Is my key stored on the hub?
Never. It lives only in your own Windmill workspace, encrypted at rest.
