Unified image generation and editing with 2K resolution

Qwen Image 2.0 Pro is an image generation and editing model developed by Alibaba's Qwen team and released in February 2026. It uses an 8B Qwen3-VL encoder paired with a 7B diffusion decoder to produce images natively at 2048×2048 resolution. A single model handles both text-to-image generation and image editing tasks, and it accepts prompts up to 1,000 tokens for detailed scene descriptions. It holds the number one position on AI Arena's blind human evaluation leaderboard for both text-to-image generation and image editing.

One of the model's defining characteristics is its ability to render accurately spelled, properly positioned text within generated images, making it suitable for infographics, presentation slides, movie posters, comics, and bilingual Chinese and English content. Its 7 billion parameter footprint is smaller than its predecessor, which used 20 billion parameters, enabling faster inference. The model is well suited for marketing teams, content creators, and designers who need production-ready visuals where accurate text rendering, high native resolution, or iterative editing workflows are priorities.

What Qwen 2 Pro supports

Text-to-Image Generation

Generates images from text prompts at native 2048×2048 resolution, accepting prompts up to 1,000 tokens for detailed layout and style descriptions.

Image Editing

Edits existing images using the same model used for generation, avoiding quality loss from chaining separate tools.

Accurate Text Rendering

Renders correctly spelled and properly positioned text inside generated images, supporting bilingual Chinese and English content without post-processing.

Native 2K Resolution

Outputs images natively at 2048×2048 pixels, rendering fine details such as skin texture and fabric weave during generation rather than via upscaling.

Seed-Based Reproducibility

Accepts a seed input to produce reproducible image outputs, enabling consistent results across repeated generation runs.

Long Prompt Support

Supports prompts up to 1,000 tokens, allowing complex descriptions of multiple visual elements, text content, and stylistic details in a single request.
