Introduction

Hello, this is Easygoing.

Today, I’d like to introduce Alibaba’s latest image generation AI model, Qwen-Image-2.1.

What is Qwen-Image-2.1?

Qwen-Image-2.1 is a new image generation AI model released by China’s Alibaba on September 20, 2026.

Alibaba has previously released two image generation AI series—Qwen-Image and Z-Image. While Qwen-Image-2.1 is the latest addition to the Qwen-Image lineup, it is in fact a completely new image generation AI model built from the ground up, with a newly developed VAE.

Architecture of Qwen-Image-2.1

Let’s take a look at the architecture of the Qwen-Image-2.1 model.

Architecture of Qwen-Image-2.1

Qwen-Image-2.1 Developer Model License
Text Encoder Alibaba Qwen3-VL (8B) Apache-2.0
Transformer Alibaba Qwen-Image-2.1_transformer Qwen Research License
VAE Alibaba Qwen-Image-2.1_vae Qwen Research License

Qwen-Image-2.1 uses Alibaba’s own Qwen3-VL as the text encoder, Qwen-Image-2.1_transformer as the Transformer, and Qwen-Image-2.1_vae as the VAE. In other words, it is a fully in-house developed model by Alibaba.

Comparison of Flux.2_vae and Qwen-Image-2.1_vae

The characteristics of an image generation AI model are largely determined by the VAE it uses.

About VAEs in Image Generation AI Models

Comparison of 3rd-Generation and 4th-Generation VAEs

Generation 3rd Generation 4th Generation
Original Resolution 1024 x 1024 x 3 1024 x 1024 x 3 1024 x 1024 x 3 1024 x 1024 x 3

Representative Models Flux.1

Flux.2
ERNIE-Image
Qwen-Image-2.1

The Qwen-Image-2.1_vae installed in Qwen-Image-2.1 belongs to the same 4th generation as Flux.2_vae. However, unlike the 3rd-generation VAEs that had very similar structures, the 4th-generation VAEs from Black Forest Labs and Alibaba differ significantly in architecture.

Qwen-Image-2.1_vae has twice the compression rate of Flux.2_vae. In theory, this means latent-space processing can be twice as fast as Flux.2. In practice, however, actual generation time also depends on model size and the number of steps, so a simple comparison is not possible.

Illustrations Generated with Qwen-Image-2.1_clear

For this article, I created Qwen-Image-2.1_clear, a fine-tuned version of Qwen-Image-2.1 optimized primarily for anime-style illustrations.

Below, I compare outputs from Qwen-Image-2.1_clear and the original Qwen-Image-2.1 side by side.

Autumn Leaves Path

Qwen-Image-2.1_clear has been adjusted to suppress residual noise and to increase saturation and contrast compared with the original.

When the two are compared, the left-side Qwen-Image-2.1_clear produces a cleaner, clearer illustration with noticeably less residual noise.

More Sample Images

Here are additional examples generated with Qwen-Image-2.1_clear.

Although the text encoder of Qwen-Image-2.1 (Qwen3-VL) is officially recommended for use with natural-language prompts, in my environment tag-style prompts consistently produced higher-quality illustrations.

Qwen-Image-2.1 Comes with a Strict Non-Commercial License

Previous Alibaba image generation AI models were released under the open Apache-2.0 license. In contrast, Qwen-Image-2.1 is distributed under Alibaba’s proprietary Qwen Research License.

About the Qwen Research License

  • Non-commercial research license only
  • Derivative models must clearly state that they are derived from Qwen
  • Users of the model assume an indemnification obligation toward Alibaba

In short, Qwen-Image-2.1 is a research-only license that explicitly prohibits commercial use.

Any derivative model of Qwen-Image-2.1 must, upon release, clearly indicate that it is a derivative of Qwen.

Users of Qwen-Image-2.1 assume an indemnification obligation toward Alibaba

Furthermore, if Alibaba suffers any damage (for example, being sued) as a result of the use of Qwen-Image-2.1, the user is obligated to cover the litigation costs and compensate Alibaba for the damage.

Like the Anima model I previously introduced, the Qwen Research License is designed to minimize risk for the rights holder and is therefore quite strict for end users.

About the Dual License of NVIDIA and the Anima Model

To reiterate: Qwen-Image-2.1 is not only non-commercial; in the event of any trouble, users also bear an indemnification obligation toward Alibaba. Please keep this firmly in mind.

Qwen-Image-2.1_clear Workflow

Because of the license restrictions above, I will not release the Qwen-Image-2.1_clear model on Civitai or Hugging Face.

Instead, I am sharing the ComfyUI workflow I used when creating Qwen-Image-2.1_clear.

Summary: Qwen-Image-2.1 Is a State-of-the-Art Image Generation AI Model

  • Qwen-Image-2.1 is a cutting-edge image generation AI
  • Qwen-Image-2.1_clear produces clean, vivid results
  • It comes with a strict non-commercial license

In this article, I introduced the Qwen-Image-2.1_clear model.

Qwen-Image-2.1 is a fascinating model that lets you experience the latest image-generation technology. At the same time, compared with previous Alibaba models, the more restrictive license undeniably makes it harder to use.

  • Bold text indicates Alibaba AI models & components

As of October 2026, many of the core components of image and video generation AI are now dominated by Chinese models. The only companies capable of developing fully open models entirely in-house are Alibaba and Tencent.

The shift of Qwen-Image-2.1 to a proprietary license may turn out to be a symbolic moment—Chinese AI models that have taken the technical lead are now beginning to move toward closed strategies.
