🔧 Node Descriptions

1. Text Node (EigenAITextNode)

Purpose: Text prompt processing and formatting Input: Text prompt Output: Processed prompt (PROMPT type) Usage:

• Add text prompt in the textarea
• Connect output to any generator node
• Supports multiline text up to 2000 characters

2. LoRA Node (EigenAILoraNode)

Purpose: LoRA model configuration and management Input: LoRA file paths and weights Output: LoRA configuration (LORA_CONFIG type) Usage:

• Set up to 3 LoRA models simultaneously
• Configure LoRA weights (0.0 to 2.0)
• Connect to generator nodes for LoRA-enhanced generation

3. Qwen Generator (EigenAIQwenGeneratorNode)

Purpose: Image generation using Qwen-compatible model Input: Prompt + LoRA config + generation parameters Output: Generated image Usage:

• Connect prompt from Text Node
• Connect LoRA config from LoRA Node
• Adjust width, height, guidance scale, and seed
• Default API: http://74.81.65.108:8010

4. Schnell Generator (EigenAISchnellGeneratorNode)

Purpose: Fast image generation using Schnell model Input: Prompt + LoRA config + generation parameters Output: Generated image Usage:

• Similar to Qwen Generator but optimized for speed
• Ideal for batch processing
• Same parameter controls as Qwen Generator

5. Kontext Generator (EigenAIKontextGeneratorNode)

Purpose: Image-to-image generation using Kontext model Input: Input image + Prompt + LoRA config + parameters Output: Generated image Usage:

• Upload or connect an input image
• Add text prompt for guidance
• Connect LoRA config for style enhancement
• Adjust generation parameters as needed

6. Upscaler (EigenAIUpscalerNode)

Purpose: Image upscaling and enhancement Input: Image + upscaling parameters Output: Upscaled image Usage:

• Connect input image from generator nodes
• Choose upscaling factor (2x or 4x)
• Apply ESRGAN upscaling for better quality

🆘 Troubleshooting

• Error: "This action is not allowed with this security level configuration." Solution: Edit:

  ComfyUI/user/default/ComfyUI-Manager/config.ini
  

  Change:

  security_level = normal
  

  to:

  security_level = weak
  

  Then restart ComfyUI.
