FAQ

Questions about Generate Leonardo Image.

What does the Generate Leonardo Image action do in Leonardo AI?

Text-to-image with model and style selection from Leonardo's curated catalog. Returns generation ID; poll Get Generation for the finished image URLs. Strong for stylised consistent batches.

What inputs does Generate Leonardo Image require?

Required: Prompt. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Leonardo AI returns an error?

The run history shows the failed step with its input and the error message Leonardo AI returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Generate Leonardo Image support batch operations?

Run Generate Leonardo Image inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Leonardo AI's rate limits.
