Input Image URL or file reference. Use a recognizable sign for editing text.
Describes what to edit in the image. Be clear about text changes or other edits needed.
Defines the precision of editing. Use 8 for balanced speed and quality.
min : 1,
max : 20
Controls adherence to prompt. Set 4 for stronger influence on changes.
min : 1,
max : 25
Ensures reproducibility of edits. Use -1 for random creative results.
min : -1,
max : 999999999999999
Choose format for image storage. 'jpeg' for compact files, 'png' for clarity.
Allowed values:
Sets image detail level. Use 80 for web content, 100 for high-quality prints.
min : 10,
max : 100
Outputs image as text. Set true if integration with text-based systems needed.
To keep track of your credit usage, you can inspect the response headers of each API call. The x-remaining-credits property will indicate the number of remaining credits in your account. Ensure you monitor this value to avoid any disruptions in your API usage.

Qwen Image Edit Guide
This guide outlines best practices and parameter recommendations for using the Qwen Image Edit model on Segmind. By adjusting key settings—steps, guidance, seed, and base64—you can optimize for speed, quality, creativity, or reproducibility.
1. Core Inputs
- •image (required): URL or file reference of the source image.
- •prompt (required): A clear, concise description of edits. E.g., “replace the text on sign board with ‘Welcome to Qwen Image Edit on Segmind’.”
2. Key Parameters
- •
steps (int, 1–20)
- •Controls the number of diffusion iterations.
- •Default: 8 for balanced speed & quality.
- •Lower (1–4): Fast, but rough results.
- •Higher (12–20): Finer details at the cost of longer runtime.
- •
guidance (float, 1–25)
- •Adjusts how strictly the model follows your prompt.
- •Default: 1 (light guidance).
- •Increase to ~4–8 for stronger adherence to text or precise edits.
- •Values above 12 can produce overfitting or artifacts.
- •
seed (int, –1 or [0 to 1e15])
- •Controls randomness and reproducibility.
- •Set
seed = –1for entirely random, creative outputs each run. - •Use a fixed positive seed (e.g., 760941192) to replicate the same result.
- •
base64 (boolean)
- •If
true, returns the edited image as a Base64 string. - •Ideal for text-based workflows or APIs that embed images in payloads.
- •Default:
falsedelivers a standard image file link.
- •If
3. Recommended Settings by Use Case
| Use Case | steps | guidance | seed | base64 |
|---|---|---|---|---|
| Quick Mockups | 4 | 1 | –1 | false |
| Precise Text Replacements | 8 | 4 | 123456789 | false |
| High-Fidelity Edits | 15 | 6 | 987654321 | false |
| Creative Variations | 12 | 2 | –1 | false |
| API/Text Integration | 8 | 4 | 555000444 | true |
4. Tips for Best Results
- •Be explicit in the prompt: mention exact wording, font style, or color when editing text.
- •Preview with low
stepsbefore scaling up. - •Lock down the seed for consistent A/B testing.
- •Gradually increase guidance to avoid unnatural artifacts.
- •Use base64 when embedding images in JSON responses.
By tailoring these parameters, you can harness Qwen Image Edit’s full power—whether you need rapid mockups, precise signboard updates, or imaginative transformations. Happy editing!
