FAQ

Questions about Generate Image.

What does the Generate Image action do in xAI?

Generates an image using Grok's image models with looser content filters than the OpenAI defaults. Useful for branding, social posts, and creative work where Grok's style fits.

What inputs does Generate Image require?

Required: Model, 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 xAI returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Generate Image support batch operations?

Yes. Run Generate Image inside a Loop node to process arrays. Tiny Command handles xAI's rate limits automatically so you don't have to throttle manually.
