What Is GLM Image?
GLM Image combines an autoregressive visual-token generator with a diffusion decoder. It is built for information-dense graphics, accurate text and knowledge-heavy prompts, while the matching edit operation accepts as many as four source images.
What Is GLM Image Best For?
- Infographics and knowledge-rich visuals
- Accurate in-image text
- Multi-subject editing
- Identity and object consistency
How to Use GLM Image
- Put exact words in quotation marks.
- Upload up to four ordered references when editing.
- Iterate at 1K.
- Use 2K for the selected information-dense final.
GLM Image Settings Explained
Guidance
The documented default is 1.5; higher values follow literal wording more strongly.
Steps
Start at 30 for drafts and use more only for a difficult final composition.
The panel above shows only the parameters GLM Image actually supports. Switch versions and unsupported controls disappear rather than sitting there doing nothing.
GLM Image Prompt Examples
Recipe infographic
Clean magazine infographic titled “RASPBERRY MOUSSE”, ingredient list on the left, four photographed steps on the right, cream and raspberry palette, exact readable labels
Multi-image edit

GLM Image Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for GLM Image, so this page shows no scores. We do not publish numbers we have not measured.
GLM Image Limitations
- The full model is slower than distilled generators
- 2K costs four times the 1K pixel tier
- Prompt expansion is disabled so pricing and wording stay predictable
GLM Image Pricing and Credits
Credits scale with resolution and image count. The Generate button always shows what this run costs.
1K

Frequently Asked Questions
Why is GLM Image useful for infographics?+
Its architecture is designed around dense knowledge and glyph fidelity rather than treating text as ordinary texture.
Does multi-reference use the same model?+
Yes. The integration selects GLM Image’s documented image-to-image companion and sends up to four images.
