GLM-Image is an AI image generation platform that transforms text-heavy prompts into high-fidelity visuals with precise text rendering, built for posters, infographics, and commercial graphics.
What is GLM-Image?
GLM-Image is a generative AI model that takes text prompts (and optionally up to four reference images in 300×300 to 2048×2048 pixel range, ≤10MB each) and outputs sharp, layout-stable images with readable text. It runs entirely in the cloud, requiring no local hardware. The model is developed by Z.ai and is available as open-source on View on GitHub and Model on Hugging Face, with supporting Read research from Z.ai.

How does GLM-Image work?
Start by writing a detailed prompt describing the desired visual and text content. Optionally upload up to four reference images. Select image size (square 1:1) and number of outputs (1–4). Click generate; the autoregressive model interprets the instruction, then the diffusion decoder produces the final image. Built-in editing and style transfer allow further refinement.
