Overview

Description:

Qwen-Image is an image-generation foundation model in the Qwen series. It achieves significant advances in complex text rendering (supporting alphabetic scripts such as English and logographic scripts such as Chinese) and precise image editing (for example, style transfer, object addition/removal, and pose manipulation). It adopts a multi-module architecture that integrates vision-language encoding and diffusion-based generation, and delivers strong performance in general image generation, text-in-image integration, and classical computer vision tasks (for example, depth estimation and novel-view synthesis).

Qwen-Image was developed by the Qwen Team.
This model is ready for commercial and non-commercial use.

Model Architecture:

Architecture Type:

Qwen-Image adopts a three-core module architecture:

1. Multimodal Large Language Model (MLLM): Qwen2.5-VL (frozen) for text/image feature extraction and semantic alignment.
2. Variational AutoEncoder (VAE): Single-encoder (frozen, adapted from Wan2.1-VAE) + dual-decoder (image-specific decoder fine-tuned) for image tokenization and reconstruction.
3. Multimodal Diffusion Transformer (MMDiT): Backbone diffusion model with novel Multimodal Scalable RoPE (MSRoPE) for joint text-image positional encoding.

Network Architecture:

• Key Components:
  • MSRoPE: Balances image resolution scaling and text positional encoding by mapping text to the diagonal of image grids.
  • Dual-Encoding Mechanism: Combines semantic features (from Qwen2.5-VL) and reconstructive features (from VAE) for editing consistency.
  • Multi-Task Training: Integrates T2I (text-to-image), TI2I (text-image-to-image), and I2I (image-to-image reconstruction) tasks.

Number of Model Parameters:

Input:

Input Type(s):

[Text]

Input Format(s):

• Text: String (supports English and Chinese).

Input Parameters:

• Text: One-Dimensional (1D), sequence of tokens.
• Context: Native support for text prompts (unlimited length in practice, optimized for paragraph-level text).

Other Properties Related to Input:

• Pre-processing:
  • Text: Tokenization via Qwen2.5-VL’s tokenizer; system prompts for task alignment (e.g., T2I: detail-rich description guidance).
• Context Length: No strict token limit for text prompts.

Output:

Output Type(s):

[Image]

Output Format:

Raster image formats (e.g., png, jpg, jpeg) via VAE decoding.

Output Parameters:

Two-Dimensional (2D), with configurable resolution (supports aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3).

Other Properties Related to Output:

• Resolution: Up to 1328×1328 (default) for high-fidelity generation; supports ultra-high resolution via multi-scale training.
• Text Fidelity: Preserves font, layout, and language coherence for text-in-image outputs (e.g., Chinese characters, English paragraphs).

Our AI models are designed and/or optimized to run on NVIDIA GPU-accelerated systems. By leveraging NVIDIA’s hardware (e.g. GPU cores) and software frameworks (e.g., CUDA libraries), the model achieves faster training and inference times compared to CPU-only solutions.

Software Integration:

The integration of foundation and fine-tuned models into AI systems requires additional testing using use-case-specific data to ensure safe and effective deployment. Following the V-model methodology, iterative testing and validation at both unit and system levels are essential to mitigate risks, meet technical and functional requirements, and ensure compliance with safety and ethical standards before deployment.

Key Considerations:

This model can generate synthetic images and may produce content that is inaccurate, offensive, or otherwise inappropriate. Users should implement robust safety guardrails — including content filtering, abuse monitoring, and access controls— to reduce the risk of harmful outputs. Users are responsible for ensuring that their use of the model complies with all applicable laws and regulations, and for regularly reviewing and updating their guardrails as risks evolve.

For more information about the implementation of Cosmos pre and post guardrails to improve model safety, please see the Cosmos-1.0 Guardrail Model.
