Idle

A realistic, high-resolution photograph of an American woman, captured in natural daylight with soft, diffused lighting that enhances her features gently. She is positioned in a candid, relaxed pose—standing outdoors near a park bench, wearing casual, contemporary clothing: a light blue denim jacket, a white t-shirt, and dark jeans. Her long, wavy brown hair falls loosely over her shoulders, and she has a subtle, thoughtful expression as she looks slightly off-camera. The background is softly blurred (shallow depth of field), with hints of greenery, a distant streetlamp, and a few passing pedestrians. Shot on a full-frame DSLR with a 50mm prime lens, emphasizing natural textures, skin tones, and environmental detail. Cinematic composition, eye-level shot, natural color grading, and a subtle film grain texture for authentic photographic realism.

Your request will cost $0.005 per run.

For $1 you can run this model approximately 200 times.

Z-Image Turbo Image-to-Image

Z-Image Turbo Image-to-Image is a versatile image generation model that offers a spectrum of modifications — from subtle enhancement to dramatic reimagination. The key is the strength parameter: at low values, it preserves your original image while enhancing quality (similar to upscaling); at high values, it uses your image as loose inspiration for entirely new creations.

This is not a simple editing tool — it's a generation engine that lets you control exactly how much of the original image to preserve.

Why Choose This?

  • Flexible transformation spectrum From near-lossless enhancement to complete style overhaul — all controlled by a single strength slider.

  • Quality enhancement mode At low strength, improve image quality, add detail, and sharpen without changing content.

  • Creative reimagination mode At high strength, use your image as a reference while dramatically changing style, composition, or subject.

  • Custom output sizing Set exact width and height for your output, independent of input dimensions.

  • Prompt Enhancer Built-in tool to automatically improve your prompts for better results.

  • Fast and affordable Turbo-optimized for quick generation at just $0.005 per image.

Understanding Strength

The strength parameter is the core of this model. It controls how much the output differs from your input image:

StrengthEffectUse Case
0.0 - 0.3Minimal change — enhances quality, adds detail, sharpensUpscaling, quality improvement, subtle refinement
0.3 - 0.6Moderate change — preserves structure, adjusts styleStyle tweaks, color grading, texture enhancement
0.6 - 0.8Significant change — keeps composition, transforms contentStyle transfer, artistic reinterpretation
0.8 - 1.0Maximum change — uses image as loose reference onlyCreative reimagination, dramatic transformation

Parameters

ParameterRequiredDescription
promptYesText description guiding the transformation
imageYesSource image to transform (upload or URL)
widthNoOutput width in pixels (default: 1024)
heightNoOutput height in pixels (default: 1024)
strengthNoTransformation intensity 0-1 (default: 0.6)
seedNoRandom seed for reproducibility (-1 for random)

How to Use

  1. Upload your image — drag and drop or paste a public URL.
  2. Write your prompt — describe the desired output or transformation.
  3. Set strength — low for enhancement, high for reimagination.
  4. Adjust output size — set width and height as needed.
  5. Run — submit and download the transformed image.

Pricing

ItemCost
Per image$0.005

Simple flat-rate pricing regardless of image size or strength setting.

Best Use Cases

  • Image Enhancement (strength 0-0.3) — Improve quality, add sharpness, enhance details without changing content.
  • Style Transfer (strength 0.5-0.8) — Apply new artistic styles while preserving composition.
  • Creative Reimagination (strength 0.8-1.0) — Use images as inspiration for entirely new creations.
  • Batch Processing — Affordable pricing enables large-scale image transformation.
  • Iterative Design — Quickly explore variations with different strength levels.

Pro Tips

  • Start with strength 0.5 to understand how the model interprets your image, then adjust.
  • For quality enhancement without content change, use strength below 0.3 with a prompt describing the desired quality.
  • For dramatic transformations, use strength above 0.8 with a detailed prompt describing the new style.
  • The prompt matters more at higher strength values; at low strength, the image dominates.
  • Use the same seed to compare different strength levels on the same image.

Notes

  • Output dimensions can differ from input — set width and height to your target size.
  • At strength 0, output will be nearly identical to input (useful for testing).
  • At strength 1, output may differ significantly while retaining some compositional elements.
