Image generation on elvex is only available to customers who also have an OpenAI account. Users must use an assistant to generate images and are blocked from doing so on the Home App.
Step 1: Set up an Image Generation Provider
Before using image generation in any assistant, an Owner or Admin must configure an image generation model:
Go to Settings > Apps
Under Image generation provider, select a provider from the dropdown
Press the Save button
Step 2: Enable Image Generation for an Assistant
By default, assistants don't have image generation enabled. To enable it:
Go to your assistant settings screen
Expand the Tools section
Enable the the Image Generation tool
Step 3: Generate Your First Image
Once enabled, you can generate images by asking your assistant and providing a description:
Open a conversation with your assistant
Type a request like: "Create an image of a dog chasing a cat in a sunny, summer mountain landscape"
Specify the model you want to use (e.g., "using GPT Image 1" or "using DALL-E 3"). If you do not specify a model, the default will be GPT Image 1.
Note: If you encounter an error when using GPT Image 1, your administrator may need to verify your OpenAI account. Please go to: https://platform.openai.com/settings/organization/general and click on Verify Organization.
Crafting Effective Prompts
To get the best results from image generation:
Be specific in your descriptions
Include details about style, lighting, and composition
Use adjectives to convey mood and atmosphere
Example: "Generate an image of a futuristic cityscape at sunset, with flying cars and neon signs, in a cyberpunk style, using DALL-E 3"
Iterate on Generated Images
If the first result isn't quite what you wanted:
Analyze what aspects of the image you'd like to change
Modify your prompt to address these aspects
Try generating the image with a different model
Generate a new image with the updated prompt
Use Advanced Features
For GPT Image 1, you can create images with transparent backgrounds by specifying it in your prompt
Experiment with different image sizes and styles, which may vary depending on the model used
