Question 1

How many input images can I send?

Accepted Answer

One to three reference images per request, as raw base64 strings in the image_b64s array. Multi-image input is how you compose subjects from separate photos, such as merging two portraits into one group shot.

Question 2

Why does the chute default to 4 steps when the model card uses 40?

Accepted Answer

The chute is configured as a low-latency serving profile: 4 inference steps with true_cfg_scale 1. The model card's example uses 40 steps with true_cfg_scale 4.0. Both fields are request parameters, so you can raise them for higher-fidelity edits at the cost of latency and compute.

Question 3

Does it keep the parts of the image I didn't ask to change?

Accepted Answer

That is the design goal, and the 2511 release specifically targets reduced image drift and improved consistency versus 2509. It is still a generative model, though: the whole frame is regenerated, so untouched regions are visually preserved rather than byte-identical.

Question 4

What license is Qwen-Image-Edit-2511 under?

Accepted Answer

Apache-2.0, per the model card's license section and the Hugging Face repo metadata. Commercial use, modification, and redistribution are permitted under standard Apache terms.

Question 5

Can I write edit instructions in Chinese?

Accepted Answer

Yes. The model is trained for English and Chinese instructions, and the model card demonstrates bilingual editing.

Question 6

How do I call it from code?

Accepted Answer

POST flat JSON to https://vonkaiser-qwen-image-edit-2511.chutes.ai/generate with an Authorization: Bearer header. Base64-encode your input image(s) into image_b64s, set prompt to the edit instruction, and save the response body as a JPEG.

Question 7

Is this a text-to-image model?

Accepted Answer

No, it is an editing model: it expects at least one reference image and an instruction describing the change. For generation from scratch use a text-to-image chute such as Qwen-Image-2512 or Z-Image Turbo.
