# Z-Image Turbo Online - Steps, Guidance, and Seed Controls

> Canonical: https://stable-diffusion-web.com/z-image

## Z-Image Turbo - text-to-image controls

The current form is text-only and exposes a required prompt, ten ratios, 1-49 inference steps, guidance 0-20, seed, output count, and paid-model access.

## Z-Image Turbo step and guidance examples

The gallery illustrates concept, portrait, product, style, illustration, and social directions; it is not a speed benchmark or output guarantee.

## Why Z-Image Turbo

The live form owns the current prompt, ratio, inference-step, guidance, seed, and output-count controls. Review every returned image instead of transferring external speed or quality claims.

### Text-only input

The current route accepts a required text prompt and does not expose reference-image input. The prompt limit is 1,800 characters.

### Ten aspect ratios

Choose 16:9, 5:4, 4:3, 3:2, 1:1, 2:3, 3:4, 4:5, 9:16, or 21:9.

### Inference steps from 1 to 49

The step control exposes 1, 8, 10, 15, 20, 25, 30, 35, 40, 45, and 49. More steps are not a universal quality guarantee.

### Guidance from 0 to 20

The guidance control exposes integer values across that range. Compare results with one variable changed at a time.

### Seed and output count

Seed supports controlled comparisons and output count requests multiple images. Neither guarantees consistency, and count can change the debit.

### Paid access with configured estimates

The catalogue requires paid-model access; metadata starts at 3 credits and estimates about 60 seconds. Confirm the live form before each run.

## Who uses this text-only model, and for what?

Designers, marketers, illustrators, and concept teams can use these candidate workflows to compare ratio, step, guidance, seed, and output-count behavior; every result still needs review.

### Creative-direction comparisons

Hold the prompt constant while changing one control, then compare composition, artifacts, detail, and debit.

### Pitch and moodboard drafts

Generate visual placeholders for internal discussion, then replace or verify assets before external publication.

### Prompt refinement

Test a focused subject, setting, light, and treatment, recording which wording produces the most usable candidate.

### Social-layout concepts

Compare horizontal, square, and vertical ratios while checking crop, text, logos, and disclosure requirements.

### Style explorations

Use the same prompt and seed to examine how guidance or steps affects a chosen visual direction.

### Output-count evaluations

Request multiple candidates only when the updated debit is acceptable, then reject weak or duplicate outputs individually.

## Z-Image Turbo steps, guidance and seed FAQ

Answers about text-only input, prompt length, ratios, inference steps, guidance, seed, output count, paid access, credits, time, rights, and review limits.

### What is Z-Image Turbo?

Z-Image Turbo is a selectable paid-access, text-only image workflow in this app. The live form defines its ratio, inference-step, guidance, seed, and output-count controls.

### Does this route accept reference images?

No. The current form exposes text input only. Choose an image-capable model when a source image must condition the result.

### How long can the prompt be?

The required prompt field allows up to 1,800 characters. A shorter, focused description is often easier to evaluate than several competing instructions.

### Which aspect ratios can I choose?

The form offers 16:9, 5:4, 4:3, 3:2, 1:1, 2:3, 3:4, 4:5, 9:16, and 21:9.

### Which inference-step values are available?

The form exposes 1, 8, 10, 15, 20, 25, 30, 35, 40, 45, and 49. Compare returned images rather than assuming more steps always win.

### Which guidance values are available?

The guidance field offers integer values from 0 through 20. Change one value at a time and compare prompt adherence with artifacts.

### How much does a run cost, and what access is required?

The catalogue marks the model as paid access and metadata starts at 3 credits with an estimated 60 seconds. Confirm the live estimate before submitting.

### Can paid-plan output be used commercially?

Paid plans include this app's commercial license. You remain responsible for prompt rights, applicable terms, and final use.

### What should I review before using an image?

Review prompt adherence, identity, anatomy, text, geometry, crop, artifacts, and delivered files. Generated images are candidates rather than verified final assets.

### What limits should I check before using Z-Image Turbo?

Generated output from Z-Image Turbo can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use.

### What happens to what I generate with Z-Image Turbo?

A result is stored against your own account, not pooled with other people’s. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure covers the generation records and the stored files it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what Z-Image Turbo makes commercially?

Every paid plan includes a commercial licence for what Z-Image Turbo makes; the free tier is for personal use.

### How does Z-Image Turbo compare, and what alternatives fit a different workflow?

Choose by the required input, delivered output, controls, limits, current availability, and credit cost; the related-tools section links each canonical page.
