About Qwen Image 3.0
Qwen Image 3.0 is the standard tier of Alibaba's Qwen Image 3.0 series, a closed model that handles text-to-image generation and image editing in one endpoint and balances quality against speed and cost.
It reads prompts up to 4,500 tokens, renders text in 12 languages, and can reason about the prompt before rendering. It takes up to three input images for edits and composition, outputs any size from 512x512 to 2048x2048 total pixels at one flat price, and picks a resolution from the prompt when none is set. Use the Pro tier when small text or complex layouts need the extra fidelity.
Weights are not published.
