ComfyUI Prompt Expansion is a custom node designed to enhance image generation by dynamically expanding prompts using GPT-2 directly on your device. It analyzes the original positive prompt and seed to incorporate additional keywords, which can significantly improve the quality of the generated images.
- Utilizes GPT-2 to automatically generate relevant keywords that enhance prompts.
- Outputs an expanded prompt that combines the original and newly generated keywords for improved image quality.
- Simple integration within ComfyUI allows for seamless usage in existing workflows.
Context
This tool serves as a custom node within ComfyUI, focusing on the enhancement of image prompts. Its primary function is to analyze and expand prompts using a local instance of the GPT-2 model, thereby enriching the input for better image generation.
Key Features & Benefits
The main feature of this tool is its ability to automatically enrich prompts with relevant keywords, which are generated based on the original input. This can lead to more detailed and higher-quality images, as it introduces additional context and specificity that may not have been present in the initial prompt.
Advanced Functionalities
The tool can log the expanded prompts to the console, providing users with visibility into how the original prompt has been modified. This transparency can help users understand the impact of the added keywords on the resulting images.
Practical Benefits
By automating the prompt expansion process, this tool streamlines the workflow within ComfyUI, reducing the manual effort required to enhance prompts. This results in improved control over image quality and efficiency, allowing users to focus on creative aspects rather than prompt engineering.
