ComfyUI Node: Attn2 Prompt Injection

Attn2 Prompt Injection:

The PromptInjection node is designed to enhance the capabilities of AI models by injecting specific prompts into the model's attention mechanism. This process allows for more precise control over the model's behavior and output, enabling you to fine-tune the model's responses to better align with your creative vision. By leveraging this node, you can manipulate the model's attention weights and conditioning, resulting in more targeted and refined outputs. This is particularly useful for AI artists who want to achieve specific artistic effects or ensure that the model adheres to particular stylistic guidelines.

Attn2 Prompt Injection Input Parameters:

model

This parameter specifies the AI model that will be used for prompt injection. It is a required parameter and ensures that the node knows which model to apply the prompt injection to.

block

This optional parameter allows you to select specific blocks within the model where the prompt injection will be applied. The available options are input:4, input:5, input:7, input:8, middle:0, output:0, output:1, output:2, output:3, output:4, and output:5. By selecting a block, you can target specific layers of the model for more granular control.

conditioning

This optional parameter allows you to provide additional conditioning to the model. Conditioning can be used to influence the model's behavior and output based on specific criteria or context.

weight

This optional parameter controls the weight of the prompt injection. It has a default value of 1.0, with a minimum value of -2.0 and a maximum value of 5.0. The weight determines the strength of the prompt injection's influence on the model.

start_at

This optional parameter specifies the starting point of the prompt injection as a percentage of the model's processing timeline. It has a default value of 0.0, with a minimum value of 0.0 and a maximum value of 1.0. This allows you to control when the prompt injection begins to take effect.

end_at

This optional parameter specifies the ending point of the prompt injection as a percentage of the model's processing timeline. It has a default value of 1.0, with a minimum value of 0.0 and a maximum value of 1.0. This allows you to control when the prompt injection stops taking effect.

Attn2 Prompt Injection Output Parameters:

model

The output parameter is the modified AI model after the prompt injection has been applied. This model will have the specified prompts injected into its attention mechanism, resulting in altered behavior and output that aligns with the provided conditioning and parameters.

Attn2 Prompt Injection Usage Tips:

• Experiment with different block options to find the most effective layers for your specific artistic goals.
• Adjust the weight parameter to fine-tune the influence of the prompt injection. Higher weights will have a stronger impact, while lower weights will be more subtle.
• Use the start_at and end_at parameters to control the timing of the prompt injection, allowing for dynamic changes in the model's behavior throughout the processing timeline.

Attn2 Prompt Injection Common Errors and Solutions:

Cannot execute because a node is missing the class_type property.

• Explanation: This error occurs when a required property class_type is missing from a node in the prompt.
• Solution: Ensure that all nodes in the prompt have the class_type property correctly defined.

Cannot execute because node {class_type} does not exist.

• Explanation: This error indicates that the specified node class type does not exist in the NODE_CLASS_MAPPINGS.
• Solution: Verify that the node class type is correctly spelled and exists in the NODE_CLASS_MAPPINGS.

Prompt has no outputs

• Explanation: This error occurs when the prompt does not produce any outputs.
• Solution: Ensure that at least one node in the prompt is configured to produce an output.
