ComfyUI Node: GR Prompt HUB

GR Prompt HUB:

The GR Prompt HUB is a versatile node designed to streamline the process of selecting and managing prompts for AI art generation. It allows you to input multiple positive and negative prompts, dynamically select which prompt to use, and combine them with a consistent prompt to ensure coherence in your generated art. This node is particularly beneficial for artists who want to experiment with different prompt combinations without manually adjusting each one. By leveraging the power of the CLIP model, the GR Prompt HUB ensures that your prompts are effectively tokenized and encoded, providing high-quality conditioning for your AI models. This node simplifies the prompt management process, making it easier to achieve the desired artistic outcomes.

GR Prompt HUB Input Parameters:

clip

This parameter expects a CLIP model instance. The CLIP model is used to tokenize and encode the provided prompts, ensuring they are in a suitable format for conditioning the AI model. This parameter is essential for the node's operation as it leverages the CLIP model's capabilities to process the text inputs.

positive_a1

This is a positive prompt string that can include multiple lines and dynamic prompts. It is one of the six possible positive prompts you can provide. The prompt will be combined with the always_a1 prompt to create a comprehensive positive prompt for the AI model.

positive_a2

Similar to positive_a1, this is another positive prompt string that supports multiline and dynamic prompts. It provides an alternative positive prompt that can be selected based on the select_prompt parameter.

positive_a3

This parameter functions like positive_a1 and positive_a2, offering another positive prompt option. It supports multiline and dynamic prompts, allowing for diverse prompt inputs.

positive_a4

This is the fourth positive prompt string, supporting multiline and dynamic prompts. It provides additional flexibility in selecting positive prompts for the AI model.

positive_a5

This parameter is another positive prompt string, similar to the previous ones. It supports multiline and dynamic prompts, contributing to the variety of positive prompts available.

positive_a6

This is the sixth positive prompt string, supporting multiline and dynamic prompts. It completes the set of positive prompts you can provide to the node.

always_a1

This is a consistent positive prompt string that will always be included with the selected positive prompt. It supports multiline and dynamic prompts and ensures a level of coherence across different prompt selections.

negative_a1

This is a negative prompt string that can include multiple lines and dynamic prompts. It is used to provide negative conditioning to the AI model, helping to steer the generated art away from undesired elements.

select_prompt

This integer parameter allows you to select which positive prompt to use, ranging from 1 to 6. The default value is 1, and it ensures that the node uses the specified positive prompt in combination with always_a1.

GR Prompt HUB Output Parameters:

positive

This output provides the conditioned positive prompt, which is a combination of the selected positive prompt and the always_a1 prompt. It is encoded and ready to be used by the AI model for generating art.

negative

This output provides the conditioned negative prompt, derived from the negative_a1 prompt. It is encoded and helps the AI model avoid generating undesired elements.

prompts

This output is a string that includes both the positive and negative prompts in a readable format. It is useful for understanding the exact prompts being used for conditioning the AI model.

GR Prompt HUB Usage Tips:

• Experiment with different combinations of positive prompts and the always_a1 prompt to see how they influence the generated art.
• Use the select_prompt parameter to quickly switch between different positive prompts without manually changing the input strings.
• Ensure that your negative prompt (negative_a1) clearly defines what you want to avoid in the generated art to achieve better results.

GR Prompt HUB Common Errors and Solutions:

"clip model not provided"

• Explanation: The CLIP model instance is missing or not correctly passed to the node.
• Solution: Ensure that you provide a valid CLIP model instance as the clip parameter.

"invalid select_prompt value"

• Explanation: The select_prompt parameter is set to a value outside the range of 1 to 6. - Solution: Adjust the select_prompt parameter to a value between 1 and 6.

"missing positive prompt"

• Explanation: One or more of the positive prompt parameters (positive_a1 to positive_a6) are not provided.
• Solution: Ensure that you provide valid strings for all the positive prompt parameters you intend to use.
