GLM-Image targets a hard problem in image generation: clean layouts with readable text. This review runs six real prompts that force titles, labels, prices, UI strings, and dense tables into one frame.<\/p>\n

What GLM-Image does<\/h2>\n

GLM-Image is a text-to-image and image-to-image model built for high-fidelity visuals and information-dense designs. It targets posters, infographics, slides, menus, and any scene where text needs to stay legible.<\/p>\n

Model page: https:\/\/wiro.ai\/models\/zai-org\/glm-image<\/a><\/p>\n

Test setup: 6 prompts, 1024×1024 output, 30 inference steps, guidance scale 1.5. Each prompt includes exact strings to render.<\/p>\n

6 prompt tests<\/h2>\n

1) Streetwear poster (headline + sizes)<\/h3>\n

This prompt checks big display type and a short spec line. The headline stays crisp. The sizes line stays readable, but spacing turns a bit weird.<\/p>\n

\n \"Minimal
Prompt: Minimalist streetwear poster, white background, green accent, centered hoodie product photo. Add crisp typography. Top line text: GLM-IMAGE TEXT TEST. Subhead: DROP 04. Footer small text: SIZES XS S M L XL. Print-ready, clean grid, high contrast, realistic fabric texture.<\/figcaption><\/figure>\n

2) Heat pump infographic (labels + arrows)<\/h3>\n

Infographics show where most models crack. GLM-Image keeps the diagram clean and the component labels readable. One letter slips in the title. Heat becomes Heal.<\/p>\n

\n \"Heat
Prompt: Educational infographic on off-white paper texture. Topic: How a Heat Pump Moves Heat. Include a simple diagram with arrows and 5 labeled callouts: Evaporator, Compressor, Condenser, Expansion Valve, Indoor Air. Add a small legend box titled KEY. Flat vector style, sharp lines, readable labels.<\/figcaption><\/figure>\n

3) Chalkboard cafe menu (items + prices)<\/h3>\n

Price lists often drift into gibberish. Here the model keeps every item and price intact. The handwriting look stays legible.<\/p>\n

\n \"Chalkboard
Prompt: Chalkboard cafe menu photo, realistic lighting, handwritten chalk style but legible. Header text: WEEKDAY MENU. Items list with prices: Espresso 3.50, Latte 4.25, Matcha 4.75, Bagel 2.95, Cookie 1.80. Add small note: Oat milk +0.50.<\/figcaption><\/figure>\n

4) Three-panel comic (short captions + speech bubbles)<\/h3>\n

Speech bubbles act like a stress test for punctuation and line breaks. The bubble text lands clean. The third caption comes out as DAY 3\/ with a stray slash.<\/p>\n

\n \"Three-panel
Prompt: Three-panel comic strip, clean ink lines, soft colors. Panel 1 caption text: DAY 1. Speech bubble: Can this model write text? Panel 2 caption: DAY 2. Speech bubble: Yes, but keep prompts structured. Panel 3 caption: DAY 3. Speech bubble: Now try a long menu. Consistent character, simple background.<\/figcaption><\/figure>\n

5) Airport departures board (dense table + status)<\/h3>\n

This prompt pushes alignment, repeated tokens, and table structure. The board looks believable. Column headers read correctly. The red DELAYED stands out. A few times show minor spacing quirks around the colon.<\/p>\n

\n \"Airport
Prompt: Airport departures board, wide shot, realistic LED matrix. Title text: DEPARTURES. Include 8 rows with columns FLIGHT, TO, GATE, TIME, STATUS. Fill with plausible entries, include at least one delayed row that says DELAYED. Keep text aligned and readable.<\/figcaption><\/figure>\n

6) Dark mode app settings UI (small text + numbers)<\/h3>\n

UI text needs crisp edges. GLM-Image renders the screen cleanly, including the timer values and version string.<\/p>\n

\n \"Dark
Prompt: Photorealistic smartphone settings screen screenshot on dark mode. App name at top: Focus Timer. Menu items with toggles: Vibration, Sound, Auto start, Break length 05:00, Session length 25:00. Small footer text: Version 2.6.1. Crisp UI, anti-aliased text.<\/figcaption><\/figure>\n

What worked (and what slipped)<\/h2>\n
