Features

Z.AI GLM-Image Image-Edit

GLM-Image Image-Edit is Z.AI’s powerful image transformation model that modifies images based on text prompts. Upload up to 4 reference images and describe the changes you want — the model reimagines your images while preserving key elements and applying your requested modifications.

Why Choose This?

• Multi-image reference Upload up to 4 reference images to guide the transformation with richer context.

• Text-guided transformation Describe changes in natural language — lighting, style, time of day, environment, and more.

• Flexible output sizing Custom width and height from 256 to 1536 pixels for any aspect ratio.

• Prompt Enhancer Built-in tool to automatically improve your prompts for better results.

• LLM-powered prompt expansion Optional feature to automatically enhance short prompts with more detail.

Parameters

Output Format Options

• jpeg — Smaller file size, good for photos and web use (default)
• png — Lossless quality, supports transparency, best for graphics

How to Use

1. Write your prompt — describe the transformation you want (e.g., “change to daytime”, “add snow”, “make it cyberpunk style”).
2. Upload reference images — add 1-4 images using ”+ Add Item” button.
3. Set size — adjust width and height (256-1536 pixels).
4. Set seed — use -1 for random results, or specify a number for reproducibility.
5. Choose output format — jpeg for smaller files, png for lossless quality.
6. Enable prompt expansion (optional) — check this to let LLM enhance your prompt.
7. Run — click Run, preview the result, and iterate if needed.

Pricing

Simple flat-rate pricing regardless of image size or number of reference images.

Best Use Cases

• Lighting Changes — Transform day to night, add golden hour, change weather conditions.
• Style Transfer — Apply artistic styles while preserving composition.
• Scene Modification — Add or remove elements, change seasons, modify environments.
• Creative Reimagining — Generate variations based on multiple reference images.
• Content Adaptation — Adjust images for different moods or contexts.

Pro Tips

• Be specific in your transformation prompt — describe exactly what should change.
• Use multiple reference images when you want to blend styles or elements from different sources.
• Enable prompt expansion for short prompts; disable it for precise control.
• Start with default 1024x1024 size, then adjust for specific aspect ratios.
• Use the same seed to compare different prompts on the same reference images.

Notes

• Maximum 4 reference images per generation.
• Size range: 256-1536 pixels for both width and height.
• enable_sync_mode is only available through the API.
• Please ensure your prompts comply with content guidelines.
