GLM Image uniquely combines autoregressive generation with diffusion decoding, first creating compact 256-token encodings, then expanding to 1K-4K tokens for ultra-high-resolution outputs. This innovative hybrid approach delivers both the semantic understanding of autoregressive models and the visual quality of diffusion systems.
Explore the technical innovations and practical advantages that make GLM Image the professional choice for serious creators.
GLM Image goes far beyond basic text-to-image generation. This powerful AI image generator excels at complex multimodal operations including image editing, style transfer, identity-preserving generation, and multi-subject consistency. The autoregressive architecture allows GLM Image to understand relationships between visual elements and maintain coherence across transformations. Whether you need to preserve facial identity while changing backgrounds, transfer artistic styles while maintaining composition, or edit specific regions without affecting the whole image, GLM Image handles these sophisticated tasks with precision and reliability.
Edit with GLM Image
GLM Image's two-stage generation process delivers exceptional quality at scale. The 9B autoregressive model first creates a dense semantic representation with approximately 256 tokens, then the 7B DiT diffusion decoder expands this to 1K-4K tokens, producing stunning 1K-2K resolution images. This architecture ensures GLM Image maintains fine details, accurate colors, and sharp clarity even at large sizes. The AI image generator produces print-ready assets suitable for professional applications including advertising, publication, product photography, and large-format displays.

Expert answers about GLM Image's innovative technology, capabilities, and applications.
GLM Image is the world's first industrial-grade open-source discrete autoregressive AI image generator, developed by Z.ai. Combining a 9B autoregressive model with a 7B DiT diffusion decoder, GLM Image creates a powerful 16B parameter hybrid architecture. This unique design allows GLM Image to excel at text rendering, knowledge-intensive generation, and complex multimodal tasks while maintaining the visual quality associated with diffusion models. GLM Image ranks first among open-source models for text accuracy with LongText-Bench scores of 0.9524 in English and 0.9788 in Chinese.
GLM Image employs an innovative two-stage hybrid architecture. The 9B autoregressive generator, initialized from GLM-4-9B-0414 with expanded vocabulary for visual tokens, first creates a compact semantic encoding of approximately 256 tokens. This encoding is then expanded to 1K-4K tokens by the 7B DiT diffusion decoder, which produces the final high-resolution image output of 1K-2K pixels. This approach combines the semantic understanding and prompt adherence of autoregressive models with the visual fidelity of diffusion systems, giving GLM Image unique advantages in text rendering and contextual generation.
Beyond standard text-to-image generation, GLM Image excels at diverse image-to-image tasks including precise image editing, artistic style transfer, identity-preserving generation, multi-subject consistency maintenance, and complex compositional transformations.
