Using Image Generation in elvex

Understand how to setup and use image generation in elvex

Updated over 2 weeks ago

This guide covers the setup, usage, and best practices for image generation in elvex. It's organized using the Diataxis framework to cater to different user needs.

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:

  1. Go to Settings > Apps

  2. Under Image generation provider, select a provider from the dropdown

  3. Press the Save button

Step 2: Enable Image Generation for an Assistant

By default, assistants don't have image generation enabled. To enable it:

  1. Go to your assistant settings screen

  2. Expand the Tools section

  3. 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:

  1. Open a conversation with your assistant

  2. Type a request like: "Create an image of a dog chasing a cat in a sunny, summer mountain landscape"

  3. Specify the model you want to use (e.g., "using GPT Image 1" or "using DALL-E 3")

Note: If you encounter an error when using GPT Image 1, you may need to verify your OpenAI account. Follow the provided link to complete the verification process.

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

Image Generation Parameters

elvex supports multiple image generation models, each with its own capabilities:

Models

GPT Image 1

  • size: Options include "1024x1024" (default), "1536x1024" (landscape), "1024x1536" (portrait), or "auto"

  • background: Options are "transparent", "opaque", or "auto" (default)

DALL-E 3

  • size: Options are "1024x1024", "1792x1024", or "1024x1792"

  • style: Options are "vivid" (default, for hyper-real and dramatic images) or "natural" (for more natural-looking images)

DALL-E 2

  • size: Options are "256x256", "512x512", or "1024x1024"

Note: When using "auto" for size with GPT Image 1, it defaults to "1024x1024".

Conclusion

Image generation in elvex now offers more flexibility and power with support for multiple AI models. By understanding how to set up, use, and optimize your prompts across different models, you can harness the full potential of this advanced image generation capability. Remember to choose the appropriate model and parameters for your specific needs, and don't hesitate to experiment with different settings to achieve the best results.
