API Parameters

Full parameter reference for the qwen-image-edit-2511 model endpoint.

ParameterTypeDescription
promptstringNatural language instruction describing the edit. Examples: 'change the background to a beach', 'make the lighting warmer'.
image_urlsarray[string]URLs of the source images to edit. Accepts 1–3 images for reference-based or multi-image editing.
negative_promptstringDescribe what to avoid in the edited output — artifacts, unwanted styles, or quality issues.
accelerationstringSpeed/quality tradeoff. 'none' for maximum quality, 'regular' for balanced, 'high' for fastest editing.
image_sizeobject | stringOutput dimensions. Defaults to input image dimensions if not specified.
num_imagesintegerNumber of edited variations to generate per request. Range: 1–4.
num_inference_stepsintegerNumber of denoising steps. 20 for fast edits, 28 for balanced, 35–50 for max fidelity. Default: 28.
guidance_scalenumberControls how closely the model follows the edit instruction. 3–5 for subtle, 6–10 for dramatic. Default: 4.5.
seedintegerReproducibility seed. Same seed + same inputs = identical output.
output_formatstringOutput image format. Options: "jpeg", "png", "webp". Default: "png".
enable_safety_checkerbooleanIf set to true, the safety checker will be enabled.
sync_modebooleanIf true, returns the image as a data URI.

Why run Qwen Image Edit 2511 on the Runflow API

Flux AI models are available on many platforms. Here's what makes the Runflow image generation API different.

Dual-path architecture

Unique two-stream design: Qwen2.5-VL captures semantic meaning (what to change), while a VAE encoder preserves appearance fidelity (what to keep).

Multi-image composition

Accepts 1–3 input images for person+person group photos, person+product placement, person+scene integration, and style transfer between images.

Bilingual text editing

Add, remove, or modify text within images in both English and Chinese with natural typography — spacing, alignment, and style consistency maintained.

Identity-preserving edits

Maintains facial identity and character consistency across edits — critical for portrait retouching, pose changes, and multi-person group photo fusion.

Open-source at 20B

Apache 2.0 licensed with full weights on HuggingFace. The largest open-source image editing model, self-hostable and customizable via LoRA fine-tuning.
