# Dall-E 3 (image generation) Node

### Overview 

The DALL-E 3 Node enables your flow to generate high-quality images using OpenAI's DALL-E 3 model. This advanced image generation node offers enhanced capabilities including better prompt interpretation, more detailed outputs, and additional customization options compared to its predecessor. The node supports both **OpenAI** and **Azure OpenAI** providers.

Usage cost: 2 credits

Configuration Settings

1. **Model Selection**
   * Model\*: Select DALL-E 3 model from available providers
   * Supported Providers:
     * OpenAI
     * Azure OpenAI
2. **Image Generation**
   * Prompt\*: Text description of the image to generate
   * Quality\*: Image quality setting
     * Standard: Regular quality, faster generation
     * HD: Higher detail and clarity, longer generation time
   * Size\*: Output resolution options
     * 1024x1024: Square format
     * 1792x1024: Landscape format
     * 1024x1792: Portrait format
   * Style\*: Image rendering style
     * Vivid: Enhanced colors and contrast

### Outputs

* `image` (Image): Generated image object for use in subsequent nodes
* `base64_image` (string): Base64-encoded image data

### Best Practices

1. **Prompt Engineering**
   * Provide detailed, clear descriptions
   * Include specific visual elements:
     * Subject matter and composition
     * Art style and medium
     * Lighting and atmosphere
     * Color palette and mood
   * Use natural language rather than keyword lists
   * Specify important details first
   * Example prompt structure:
     * "A professional photograph of \[subject] in \[setting], \[lighting], \[style]"
2. **Quality Selection**
   * Use Standard quality for:
     * Rapid prototyping
     * Draft versions
