ComfyUI Extension: Comfyui_MiniCPMv2_6-prompt-generator

Comfyui_MiniCPMv2_6-prompt-generator Introduction

The Comfyui_MiniCPMv2_6-prompt-generator is an extension designed to automatically generate image labels or prompts, which can be particularly useful for AI artists working with LoRA (Low-Rank Adaptation) or DreamBooth training on flux series models. This extension leverages a fine-tuned model, MiniCPMv2_6-prompt-generator, to create natural language descriptions for images. These descriptions can be short or long prompts, making it easier to generate training data for various AI art projects.

How Comfyui_MiniCPMv2_6-prompt-generator Works

The extension works by using a fine-tuned version of the MiniCPM-V 2.6 model, which has been trained on a dataset of MidJourney prompts. This model can generate captions and prompts for images in a natural language style. The process involves uploading an image and selecting the desired caption method (single-image caption, short prompt, or long prompt). The model then processes the image and generates the corresponding text output.

Basic Workflow for Image Caption or Prompt Generation

1. Single-Image Caption: Upload an image and set the caption_method to "caption". The model will generate a descriptive caption for the image. single image caption

2. Short Prompt Generation: Upload an image and set the caption_method to "short_prompt". The model will generate a concise prompt for the image. short_prompt

3. Long Prompt Generation: Upload an image and set the caption_method to "long_prompt". The model will generate a detailed prompt for the image. long_prompt

4. Image Regeneration: Use the generated prompt as input to a CLIP node to regenerate the image through a text-to-image (t2i) model. Image regenerate

Comfyui_MiniCPMv2_6-prompt-generator Features

Single-Image Caption

• Description: Generates a descriptive caption for a single image.
• Customization: Set the caption_method to "caption".
• Example: Upload an image of a sunset, and the model might generate a caption like "A beautiful sunset over the ocean."

Short Prompt Generation

• Description: Generates a short, concise prompt for an image.
• Customization: Set the caption_method to "short_prompt".
• Example: Upload an image of a cat, and the model might generate a prompt like "A cute cat sitting on a windowsill."

Long Prompt Generation

• Description: Generates a detailed, descriptive prompt for an image.
• Customization: Set the caption_method to "long_prompt".
• Example: Upload an image of a forest, and the model might generate a prompt like "A dense forest with tall trees and a narrow path winding through it."

Batch Image Caption

• Description: Generates captions for multiple images in a folder.
• Customization: Indicate the image folder path, and the system will read all images in the folder and generate captions for each image.
• Example: Upload a folder of vacation photos, and the model will generate captions for each photo, saving them as text files with the same names as the images. Batch image caption

Comfyui_MiniCPMv2_6-prompt-generator Models

The extension uses the MiniCPMv2_6-prompt-generator model, which is fine-tuned on a MidJourney prompt dataset. This model can generate both short and long prompts for images in a natural language style. The model is trained with over 3000 samples, including images and prompts sourced from MidJourney, and it operates efficiently with lower GPU memory usage (about 7GB) when using the int4 quantized version.

Troubleshooting Comfyui_MiniCPMv2_6-prompt-generator

Common Issues and Solutions

1. Model Not Downloading Automatically

• Solution: Ensure that the model is placed in the ComfyUI\models\LLM\ directory. If not, download it manually from MiniCPMv2_6-prompt-generator.

2. High GPU Memory Usage

• Solution: Use the int4 quantized version of the model to reduce GPU memory usage to about 7GB.

3. Incorrect Captions or Prompts

• Solution: Verify that the correct caption_method is set. Experiment with different images to see if the issue persists.

Frequently Asked Questions

• Q: Can I use this extension for batch processing?
• A: Yes, you can process multiple images by indicating the image folder path for batch captioning.
• Q: What types of prompts can the model generate?
• A: The model can generate short prompts, long prompts, and descriptive captions for images.
