Generation Parameters

Each parameter has its own "personality". Understanding them helps you avoid pitfalls and save credits.

Not a pro? No problem

If you're not familiar with these parameters, you don't need to actively tweak them — the defaults are already a strong combination, and the output will be good enough out of the box.

If you accidentally break things, head to Settings and tap "Reset to default" to restore the system defaults in one tap.

Width × Height

Determines aspect ratio and resolution.

Use caseRecommended sizeNotes
Portrait (character art, person)832 × 1216Best for single subject, natural composition
Landscape (scenery, scene)1216 × 832Best for environment, group shots
Square (avatar)1024 × 1024Universal size, ideal for social avatars

WARNING

Larger canvases cost more, and total pixel count drives cost more than dimensions per se. Unless you specifically need high resolution, the sizes above are recommended.

Count

How many candidate images to generate at once.

  • Want to save credits: pick 1
  • Want options to choose from: pick 2–4

Cost scales linearly with count — generating 4 costs roughly 4× as much.

TIP

When you're not sure whether your prompt is well-tuned, generate 1 first to test. Once stable, use 4 to get more compositions.

Steps

Number of sampling iterations the model runs. More steps mean finer details but higher cost.

Steps rangeBest forOutput traits
20–24Quick previews, composition testsOverall shape OK, details a bit rough
28–32Daily use (recommended)Sufficient detail, best value
40+Extreme detailDiminishing returns, often imperceptible

Prompt Guidance

The "guidance strength" of your prompt. Higher values make the AI follow your prompt more strictly; lower values let it improvise.

RangeBehavior
Below 3.0Too much improvisation — easily off-topic
5.0 – 6.0Natural, picture-like (default recommended)
7.0 – 8.0Strict to the prompt but tends to feel stiff
9.0+Overexposure, color saturation issues, increased risk of breakdown

Prompt Guidance Rescale

When Prompt Guidance is high (≥7.0), the output may suffer from overexposure or color distortion. Prompt Guidance Rescale is used to "soften" the over-strong guidance and produce more natural images.

  • 0.0 (default): no softening
  • 0.1 – 0.3: gentle softening, pairs with high Prompt Guidance
  • 0.5+: heavy softening, abstract feel

If you keep Prompt Guidance in the 5.0–6.0 sweet spot, leave Prompt Guidance Rescale at 0.

Sampler / Noise Schedule

Controls the algorithmic path during generation. The defaults handle the vast majority of cases; advanced users can experiment with different combinations for varied feel.

Different Samplers have different preferences:

  • Toward photoreal / stable → default Sampler + default Noise Schedule
  • Toward anime / stylized → try ancestral Samplers (those marked _a or ancestral)
  • For sharper detail → karras-family Noise Schedules typically perform better

TIP

If you're not familiar, don't change these two — many combinations are mismatched, and random tweaks may break the output.

Seed

The "password" that controls randomness.

  • Empty / random: every run produces a different result (recommended)
  • Specific number: same prompt + same Seed ≈ consistent output (reproducible)

Common technique

Lock the Seed + tweak the prompt: after finding an image you like, fix its Seed, then change just one keyword in your prompt (hair color, outfit, etc.) to get "the same character, different versions" series.

VarietyPlus

Increases diversity across multiple images in the same batch (composition, pose, viewpoint).

  • Off: similar outputs in the batch — easier to pick the most stable version
  • On: more variety in the batch — better for exploring compositions

When generating only 1 image, this toggle has no effect. For 2–4 images, turning it on prevents the "all 4 look identical" problem.

Tips

  • First time: keep all parameters default; tune the prompt first
  • Once stable: tweak canvas size and count
  • Don't change multiple at once: change one at a time to identify what's making the difference
