ComfyUI Node: LayerUtility: PromptTagger(Advance)

LayerUtility: PromptTagger(Advance):

The LayerUtility: PromptTagger is a sophisticated tool designed to assist AI artists in generating refined text prompts for image generation using Stable Diffusion. This node leverages advanced generative AI models to transform image descriptions into coherent and grammatically correct prompts, enhancing the quality and relevance of the generated images. By allowing users to specify words to exclude or replace, the PromptTagger offers a high degree of customization, ensuring that the generated prompts align closely with the user's creative vision. The node's primary goal is to streamline the prompt creation process, making it more intuitive and efficient, while also providing the flexibility to adjust the prompt's content dynamically based on user input.

LayerUtility: PromptTagger(Advance) Input Parameters:

image

This parameter accepts an image input, which serves as the basis for generating the text prompt. The image is processed to extract descriptive elements that are then translated into a textual format. The quality and content of the image directly influence the resulting prompt.

api

The api parameter allows you to select the generative AI model to be used for prompt generation. Available options include gemini-1.5-flash and gemini-pro-vision. Each model may offer different capabilities or performance characteristics, so choosing the right one can impact the quality and style of the generated prompt.

token_limit

This integer parameter sets the maximum number of tokens allowed in the generated prompt. It has a default value of 80, with a minimum of 2 and a maximum of 1024. Adjusting this limit can help control the length and detail of the prompt, ensuring it remains concise or allowing for more elaborate descriptions as needed.

exclude_word

A string parameter that specifies words to be excluded from the generated prompt. This allows for greater control over the content, ensuring that certain terms or phrases are omitted from the final output. By default, this is an empty string, meaning no words are excluded unless specified.

replace_with_word

This string parameter is used to replace specified words in the generated prompt. It provides a mechanism to substitute certain terms with preferred alternatives, enhancing the prompt's alignment with your creative intent. By default, this is an empty string, indicating no replacements unless specified.

LayerUtility: PromptTagger(Advance) Output Parameters:

text

The output parameter text is a string that contains the generated prompt. This prompt is crafted based on the input image and any specified parameters, such as excluded or replaced words. The output is designed to be a coherent and grammatically correct prompt suitable for use in image generation tasks with Stable Diffusion.

LayerUtility: PromptTagger(Advance) Usage Tips:

• Experiment with different api options to find the model that best suits your style and needs, as each may produce slightly different results.
• Use the token_limit parameter to control the verbosity of the prompt. A lower limit can help keep prompts concise, while a higher limit allows for more detailed descriptions.
• Take advantage of the exclude_word and replace_with_word parameters to fine-tune the prompt content, ensuring it aligns with your specific requirements or creative vision.

LayerUtility: PromptTagger(Advance) Common Errors and Solutions:

"Invalid API Key"

• Explanation: This error occurs when the API key used for accessing the generative model is incorrect or expired.
• Solution: Verify that the API key is correct and active. Update the key if necessary by obtaining a new one from the service provider.

"Token Limit Exceeded"

• Explanation: The generated prompt exceeds the specified token limit, which can happen if the input image is complex or the token limit is set too low.
• Solution: Increase the token_limit parameter to accommodate a longer prompt or simplify the input image to reduce the complexity of the generated text.

"Model Not Available"

• Explanation: The selected generative model is not available, possibly due to service downtime or incorrect API selection.
• Solution: Check the availability of the model and ensure the correct api option is selected. If the issue persists, try using an alternative model.
