Image Generation in HallianAI

Available in HallianAI v6.5.0 and later

HallianAI now supports AI image generation directly within the platform using advanced models like GPT Image 1.5 and Nano Banana 2. All images are generated within your private AI environment —no external tools, no data exposure.

This article covers guidelines for two primary audiences: Marketers and Engineers.

Image Generation for Marketers

Marketing teams can use HallianAI to generate on-brand visuals, social content, presentation assets, and creative concepts—faster and without leaving the platform.

Getting Started

Navigate to the Assistant tab, select a vision-capable model (GPT Image 1.5 or Nano Banana 2), and describe the image you want to generate in your prompt.

Writing Effective Image Prompts

The quality of your output depends on the specificity of your prompt. Think of it as briefing a designer—the more context you provide, the better the result.

Include in every prompt:

• Subject: What is the main focus of the image?
• Style: Photorealistic, illustrated, flat design, abstract, etc.
• Mood/Tone: Professional, energetic, calm, bold, minimal
• Composition: Wide shot, close-up, overhead, centered
• Format/Ratio: Square (social), landscape (banner), portrait (print)

Example prompt:

"Generate a professional, photorealistic image of a modern open-plan office with natural lighting. The mood should be collaborative and energetic. Wide landscape format suitable for a website hero banner."
