Qwen-Image-3.0 is the third generation of Alibaba's Qwen image model, and like the 2.0 series it folds generation and instruction-based editing into a single model id rather than splitting them across endpoints.

One prompt, measured through the gateway
qwen-image-3.0
Model returned 1024×1024 latency 68 s
One prompt, one request per model, no retries and no cherry-picking - the first result each model returned. Neither size nor duration was pinned: each model used its own default, because a request shaped to fit all of them would flatter none. Files here are re-encoded for the web, so judge composition and prompt adherence, not compression.

- The official documentation describes a synchronous request carrying a prompt and, for editing, one to three reference images; when no size is supplied the model recommends a resolution itself.
- Total output pixels are documented from 512x512 to 2048x2048 with aspect ratios from 1:8 to 8:1, results come back as PNG, and a single call returns one to six images.
- One billing detail is new to this generation and worth planning around: reference images passed in for editing are metered separately from the images the model generates, so an edit carrying three references costs more than a plain text-to-image call at the same output count.
- Synthorai serves it through the OpenAI-compatible image generation endpoint.
FAQ
Is the qwen-image-3.0 API free to try?
Yes: new accounts get 10 trial calls and up to $1 in free credit, no card required. That's enough to try qwen-image-3.0 against your real workload before adding a payment method.
What is qwen-image-3.0 best at?
Generation and instruction editing under one model id; 1-3 reference images for guided edits; PNG output, 1-6 images per request. See the About section for the full picture from the vendor's own release notes.
How much does qwen-image-3.0 cost?
qwen-image-3.0 costs $0.03 per generated image on Synthorai: pay-as-you-go, no platform markup, no subscription.
How do I generate images with the qwen-image-3.0 API?
POST to /v1/images/generations on Synthorai with model="qwen-image-3.0". It follows the OpenAI images API shape, so no vendor SDK is needed. Supported sizes: custom WxH (total pixels 512x512 - 2048x2048), aspect ratio 1:8 - 8:1, resolution auto-recommended when size is omitted.
How do I get access to qwen-image-3.0?
Point your existing OpenAI SDK at base_url="https://synthorai.io/v1", set model="qwen-image-3.0", and you're done. One API key covers every model on the gateway.
