Dall-E 2 (image generation) Node

Overview

The DALL-E 2 Node enables your flow to generate images using OpenAI's DALL-E 2 model. This node transforms text descriptions into high-quality images, making it ideal for applications requiring automated image generation, creative content production, or visual asset creation.

Usage cost: 2 credits

Configuration Settings

1. Model Selection

   • Model*: Select OpenAI's DALL-E 2 model from available providers

   • Note: Only OpenAI provider is supported for DALL-E 2

2. Image Generation

   • Prompt*: Text description of the image to generate

   • Image Size*: Select output resolution

     • 256x256: Small size, faster generation

     • 512x512: Medium size, balanced option

     • 1024x1024: Large size, highest detail

Outputs

• image (Image): Generated image object for use in subsequent nodes

• base64_image (string): Base64-encoded image data

Best Practices

1. Prompt Engineering

   • Be specific and detailed in descriptions

   • Include key visual elements:

     • Style (e.g., "photorealistic", "oil painting", "3D render")

     • Composition (e.g., "close-up", "wide angle", "overhead view")

     • Lighting (e.g., "bright", "moody", "natural lighting")

     • Colors (e.g., "vibrant", "pastel", "monochromatic")

   • Maintain prompt clarity and coherence

2. Size Selection

   • Choose 256x256 for:

     • Thumbnails and previews

     • Quick iterations and testing

     • Resource-efficient generation

   • Choose 512x512 for:

     • Medium-quality assets

     • Social media content

     • Balance between quality and speed

   • Choose 1024x1024 for:

     • High-quality visuals

     • Detailed illustrations

     • Professional content

Common Issues

• API rate limiting

• Network timeouts during image fetching
