In corporate environments, Z Image API can support internal knowledge sharing by generating visuals for onboarding materials, training decks, and documentation. Its lightweight design allows teams to produce multiple diagrams or explainer visuals efficiently across internal systems and platforms.

Product Documentation & Explainer Content

Z-Image Turbo API integrates naturally into product and developer documentation workflows, where visuals are used to reinforce written explanations. It is particularly useful for generating diagrams and explanatory graphics that help users understand features, processes, or system behaviour without overwhelming them visually.

Z-Image API Examples

Below are text-to-image examples that demonstrate how Z Image Turbo API can be used across educational and informational scenarios. These prompts are designed to produce clear, structured and readable visuals.

Example 1: Educational Poster

In this first example, we’ll craft a prompt for a clean, educational ready diagram.

AI Generated Image of Educational Poster by Z Image API — Prompt: Create a simple educational diagram showing the life cycle of a plant arranged from left to right with three stages, and add a centered title at the top in both English and Chinese reading “Plant Life Cycle / 植物生长周期”. Stage 1 is labeled “Seed / 种子” and shows a small seed planted in soil, Stage 2 is labeled “Young Plant / 幼苗” and shows a small green plant with several leaves growing from the soil, and Stage 3 is labeled “Mature Plant / 成熟植物” and shows a fully grown plant with a strong stem, multiple leaves, and visible flowers. Connect each stage with clear arrows to indicate progression, and use a flat illustration style with soft natural colors, a white background, consistent icon and illustration style, and clear, readable bilingual labels placed under each stage.

We prompted the model to generate a simple plant life cycle diagram with clear stages and bilingual labels. This reflects how educational teams create structured visuals for lessons and worksheets, where clarity and progression are key.

Example 2: Informational Poster

This example demonstrates how Z Image Turbo API can be used to generate a public-facing informational poster, where layout clarity and message hierarchy are essential.

AI Generated Image of Informational Poster by Z Image API — Prompt: Design an informational fire safety poster with three vertically stacked sections. Design an informational fire safety poster with three vertically stacked sections on a white background. The first section has the title “Emergency Exit” with the description “Follow exit signs to leave the building safely” and a simple flat safety icon showing a person running toward an exit door with an arrow. The second section has the title “Fire Extinguisher” with the description “Use only if the fire is small and you are trained” and a flat vector icon of a fire extinguisher next to a small flame. The third section has the title “Do Not Use Lift” with the description “Use stairs instead” and a flat warning icon showing an elevator with a fire symbol and a diagonal prohibition line. Use high-contrast safety colors such as red, white, and black, large readable sans-serif text, consistent flat icon style, clear spacing between sections, and a clean public-safety poster layout. Use high-contrast safety colors (red, white, and black), large readable sans-serif text, consistent flat icon style, clear spacing between sections, white background, and a clean public-safety poster layout.

Here, we ask for a fire safety poster with high-contrast sections, clear icons, and concise instructions. This mirrors real-world public information design, where messages need to be understood quickly at a glance.

Example 3: Corporate Training Visual

Here, the prompt targets internal training and onboarding materials, where visuals support structured explanations and need to remain consistent across documents.

AI Generated Image of Training Visuals by Z Image API — Prompt: Create a corporate compliance training visual about data privacy responsibilities using a clean 2×2 grid layout on a white background. Add a centered top title reading “Data Policy” in bold sans-serif typography. Create four equal rectangular panels with subtle rounded corners, consistent padding, and uniform spacing. Each panel contains an icon at the top, a bold heading, and very short bullet-style text lines. The panels are: “Data Collection” with the line “Collect only necessary data” and a clipboard icon; “Data Storage” with the line “Store in secure systems” and a locked database icon; “Data Access” with the line “Role-based access only” and a key or ID badge icon; and “Data Sharing” with the line “Use approved channels” and a shield or share-with-lock icon. Use a professional color palette with navy or blue accents, dark gray text, light gray panel backgrounds, crisp readable typography, and no gradients, shadows, or decorative backgrounds.

In this case, the prompt focuses on a grid-based data privacy training visual. This aligns with how organizations present compliance information internally in a clear, scannable format for onboarding and training.

Example 4: Product Documentation & Explainer

In this final example, the prompt is designed for product documentation, where visuals are used to reinforce written explanations without adding unnecessary complexity.

AI Generated Image of Product Explainer by Z Image API — Prompt: Create a product explainer diagram for an ergonomic office chair designed for long working hours using a centered layout on a white background with a title at the top reading “Ergonomic Chair Key Features.” Display a front-facing illustration of the chair in the center of the layout. Around the chair, place four labeled callout boxes with thin connector lines pointing to specific parts of the chair. The callouts are: “Adjustable Headrest” with the sub-label “Neck Support,” “Lumbar Support” with the sub-label “Lower Back Comfort,” “Seat Height Control” with the sub-label “Maintain Posture,” and “Flexible Armrests” with the sub-label “Reduced Arm Strain.” Use a flat vector illustration style, neutral professional colors, clear readable labels, consistent icon style, minimal visual noise, and a layout that resembles a product manual or brochure explainer.

For this example, we generate a product explainer highlighting key ergonomic chair features using labeled callouts. This matches how product teams design documentation visuals that support manuals.
