Image generation on elvex is only available to customers who have configured an image generation provider. Users must use an agent 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 agent, 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
Note: elvex supports multiple image generation providers, including OpenAI and Google AI.
Step 2: Enable Image Generation for an Agent
By default, agents don't have image generation enabled. To enable it:
Go to your agent settings screen
Expand the Actions section
Enable the Image Generation action
Step 3: Generate Your First Image
Once enabled, you can generate images by asking your agent and providing a description:
Open a conversation with your agent
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 gemini-2.5-flash-image"). If you do not specify a model, the system will use the default model for your configured provider
Note for OpenAI users: 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. Note that it may take up to 15 minutes for the changes to propagate.
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 gpt-image-1"
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 OpenAI's GPT Image 1, you can create images with transparent backgrounds by specifying it in your prompt
Experiment with different image sizes (OpenAI only) and styles
Google AI models offer fast generation with competitive quality
