Image Generation

Configure AI-powered cover page images for your VET learning packs. Our image generator creates stunning, professional backgrounds that reflect your industry context.

🎨

How It Works

  • Images are generated using Google Imagen 4.0 Ultra
  • Prompts combine your master template with stream-specific scenes
  • Each unit gets a unique, contextual cover image
  • Fallback to Gemini 2.0 Flash if needed

📎 Connected to Runs

  • Cover images are generated in the Run Detail page
  • Use the Image Intensity slider when creating a run
  • Higher intensity = more detailed, professional images
  • Images are included in your ZIP download

🛠 Customisation

  • Edit the Master Prompt below to change style
  • Each Stream has its own scene description
  • Colour grades set the overall tone
  • Equipment keywords add industry-specific details

🌟 Best Practices

  • Keep prompts descriptive but concise
  • Use Australian industry terminology
  • Mention specific equipment for realism
  • Set intensity to 8-10 for best quality

Tip: The image is generated during the content creation pipeline. Go to the Dashboard and click on any run to see the cover image section with preview and regeneration options.
Generate New Prompt: On the Run Detail page, use the "Generate New Prompt" button to create an AI-powered prompt tailored to the specific unit and stream. The AI uses your stream context (equipment, materials, processes) to generate accurate, industry-specific descriptions.

Master Prompt Template Global Settings

This template is used for all cover images. Placeholders are replaced with unit and stream-specific values.

Available Placeholders:
{stream_scene} {unit_code} {unit_title}

Stream Scene Templates Per-Stream

Each industry stream has its own scene description, colour grade, and equipment keywords that make images contextually relevant.

Note: Changes here affect all future image generations for that stream. Existing images won't change until you regenerate them.

Section Banner Generation 8-Banner System

Generate 16:9 section banners for your learning materials. Each stream gets 8 banners: 2 cycles (A/B variants) x 4 sections, providing visual variety.

Note: Banner generation may take 5-10 minutes per stream (8 banners). Each slot can retry up to 3 times if validation fails. Generated banners are saved as drafts and require approval before use.

House Style Guide & Prompt Templates

Download the guide to learn how to create custom banner prompts using ChatGPT. All prompts must follow the house style rules for consistent, high-quality images.

  • No identifiable faces (people from behind/blur)
  • 16:9 banner with negative space on left
  • Photorealistic industrial scenes
Creating Custom Prompts: Use the guide to ask ChatGPT to generate prompts for new streams or variations. Include the stream name, section type (orientation/process/WHS/troubleshooting), workplace context, and all house style rules.

⚙️ Pipeline Configuration
Feature Flag
course_builder — must be enabled per organisation via feature flags
Generation Pipeline
Course Builder runs skip Stage A/B. The blueprint is pre-built by the adapter, then goes straight to Stage C content generation.
AI Routing Stages
course_design — conversation AI for outline design
course_design_research — TGA-specific research framework for industry/regulatory context
Cost Tracking
All AI calls use cost_category="setup" and track via the unified AiUsageEvent system.
Adapter
app/services/course_builder_adapter.py converts CourseOutline → UnitBlueprint format for Stage C compatibility.
