Qwen Image 2.1 is an image generation and editing series from Qwen, Alibaba's model family. One model takes a prompt alone, or a prompt with reference images when you want to edit a photo or compose from several. It ships in two tiers with identical settings: Qwen Image 2.1 Pro, the higher quality tier, and Qwen Image 2.1 Turbo, the faster tier at a lower price per image.

On Treza both sit in the Image Generation node's model picker, and you can ask for either one by name in chat. Pick 1K or 2K and one of thirteen aspect ratios, attach up to 4 references, and wire the finished still into the rest of the pipeline, which publishes as one API.

Two tiers, one spec sheet

Pro and Turbo take the same inputs and settings, so a node can switch tiers without touching anything else.

Generate and edit in one model

Write a prompt to start fresh, or attach a photo and describe the change. The same node does both.

Tall and wide formats

Thirteen aspect ratios from 1:4 to 4:1, for vertical stories, banner strips, and everything in between.

Up to 4 references

Combine a product, a setting, and a style reference in one request and compose a single image from them.

What to make with Qwen Image 2.1

Prompts to try, and what to expect back. Each runs on an Image Generation node with Qwen Image 2.1 Pro or Turbo picked in the model menu.

Qwen Image 2.1 is one node on a canvas

Chain it with language, image, and video models, then publish the whole pipeline as an API. See how a full AI video pipeline fits together.

Step 01
Draft the brief
A language model node expands a one-line idea into a detailed, on-brand prompt before it ever reaches the model.
Step 02
Generate with Qwen Image 2.1
Run variants in parallel, compare against other models on the same prompt, and keep every result in run history.
Step 03
Publish it as an API
The pipeline becomes a versioned endpoint. Your product calls it with the typed /invoke API or any OpenAI SDK.

Qwen Image 2.1 as an API, priced per image

The Qwen Image 2.1 API

Build a pipeline with Qwen Image 2.1 on a node and publish it. It becomes a versioned HTTP endpoint: the typed /invoke route enqueues a run and returns a run id to poll, and an OpenAI-compatible route works with SDKs you already use. Agents connect over MCP the same way. Your prompt engineering ships inside the pipeline, so every caller gets your quality, and swapping the model later does not change the API your product calls.

Qwen Image 2.1 pricing

Prepaid credits, no subscription. Each image is charged at Qwen Image 2.1's own rate from your balance, shown before you run, and a failed generation costs nothing. Credit packs start at $5 and never expire, which suits spiky production schedules. Run history records the cost of every generation, per node, so spend is auditable rather than a surprise.

Qwen Image 2.1, answered

What is the difference between Qwen Image 2.1 Pro and Turbo?

They take the same inputs: a prompt, up to 4 reference images, 1K or 2K output, and thirteen aspect ratios. Pro is the higher quality tier; Turbo is the faster tier at a lower price per image. Run one prompt through both on two nodes and let the output decide.

How is Qwen Image 2.1 different from Qwen Image 3?

Both generate and edit, at 1K or 2K, with the same thirteen aspect ratios and up to 4 references. Qwen Image 3 is built for precise small text, down to 10 pixels. Qwen Image 2.1 renders faster, which makes it the one to use in chat when you want a still back quickly.

Can I use Qwen Image 2.1 in Treza chat?

Yes. Ask for Qwen Image 2.1 Pro or Qwen Image 2.1 Turbo by name and chat renders the image in the conversation. On the canvas, both are in the Image Generation node's model picker.

How much does Qwen Image 2.1 cost on Treza?

Treza uses prepaid credits with no subscription. Each image is charged at Qwen Image 2.1's rate from your balance, and only successful generations are charged. Credit packs start at $5 and never expire.

Can I call Qwen Image 2.1 through an API?

Yes. Build a pipeline that uses Qwen Image 2.1 and publish it as a versioned HTTP endpoint. Call the typed /invoke API from your product, or point any OpenAI SDK at the OpenAI-compatible endpoint. If a better model ships later, swap it on the node without changing the API your product calls.
