ComfyUI Node: Prompt Generator Options

Prompt Generator Options:

The PromptGenOptions node is designed to enhance your experience in generating creative and detailed prompts for text-to-image generation. It provides a flexible interface to control various parameters and models, allowing you to tailor the prompt generation process to your specific needs. This node is particularly beneficial for AI artists who wish to explore different modes of prompt enhancement and image analysis, offering options to enhance user prompts, analyze images, or combine both with custom instructions. By leveraging this node, you can seamlessly integrate local and HuggingFace models, customize instructions for language models, and choose from multiple operational modes to achieve the desired output. The PromptGenOptions node is an essential tool for those looking to optimize their creative workflows and produce high-quality, imaginative prompts.

Prompt Generator Options Input Parameters:

model

This parameter allows you to select the model to be used for prompt generation. You can choose from available local models or HuggingFace models, with local models listed first. The default value is the first available model, if any. Selecting the appropriate model can significantly impact the quality and style of the generated prompts, as different models may have varying capabilities and strengths.

image2

This parameter requires you to connect an image, which is necessary for the 'Analyze Image' and 'Analyze Image with Prompt' modes. By providing an image, the node can analyze visual content to generate more contextually relevant prompts.

image3

Similar to image2, this parameter requires an image connection for the 'Analyze Image' and 'Analyze Image with Prompt' modes. It ensures that the node has sufficient visual data to perform a comprehensive analysis.

image4

This parameter also requires an image connection for the 'Analyze Image' and 'Analyze Image with Prompt' modes, contributing to the node's ability to analyze and generate prompts based on visual input.

image5

Like the previous image parameters, image5 requires an image connection for the 'Analyze Image' and 'Analyze Image with Prompt' modes, further enhancing the node's analytical capabilities.

system_prompt

This parameter allows you to input custom instructions for the language model. It supports multiline text and has a default empty value, with a placeholder suggesting to replace LLM instructions. If left empty, the default instructions are used, which are designed to generate detailed and imaginative prompts for text-to-image generation. Customizing this parameter can help tailor the output to specific creative needs.

Prompt Generator Options Output Parameters:

options

The options output provides a structured set of parameters that control the model and its execution settings. This output is crucial for ensuring that the prompt generation process adheres to the specified configurations, allowing for consistent and predictable results.

Prompt Generator Options Usage Tips:

• To achieve the best results, carefully select the model that aligns with your creative goals, as different models may produce varying styles and qualities of prompts.
• Utilize the system_prompt parameter to customize instructions for the language model, which can help generate prompts that are more aligned with your specific artistic vision.
• When using the 'Analyze Image' modes, ensure that the connected images are of high quality and relevant to the desired prompt context to enhance the accuracy and relevance of the generated prompts.

Prompt Generator Options Common Errors and Solutions:

Model not selected

• Explanation: This error occurs when no model is selected for prompt generation.
• Solution: Ensure that you select a model from the available options before proceeding with the prompt generation process.

Image not connected

• Explanation: This error arises when an image is required for analysis, but none is connected to the node.
• Solution: Connect the necessary image(s) to the appropriate input parameters (image2, image3, image4, or image5) to enable image analysis.

Invalid system prompt

• Explanation: This error happens when the system_prompt contains invalid or unsupported instructions.
• Solution: Review and adjust the system_prompt to ensure it contains valid and supported instructions for the language model.
