Using Lora Models in Prompts

To use a Lora model, include it directly in your image generation prompt using the following syntax: <lora:model_name:weight>. For instance, if you're using a Lora model named “fantasy_style” and want a moderate influence, your prompt might look like this:

A dragon soaring over a castle <lora:fantasy_style:0.5>

Using Lora Models in Negative Prompts

Similarly, Lora models can be used in negative prompts to avoid certain styles or elements. The syntax remains the same, but you place it in the negative prompt field: <lora:model_name:weight>. For example, to avoid a cartoonish look, you might use: 


Adjusting Weight and Multiplier for Desired Effects

The weight and multiplier are crucial parameters for controlling the influence of Lora models on the generated images. Here are some tips for adjusting these parameters:

  1. Weight: The weight determines the overall influence of the Lora model on the generated image. Higher weights will result in a stronger effect, while lower weights will have a more subtle impact. Experiment with different weight values to achieve the desired balance between the base model and the Lora model.
  2. Multiplier: The multiplier is used to control the strength of the Lora model's effect on specific layers of the base model. Higher multiplier values will amplify the effect on the corresponding layers, while lower values will reduce it. Adjusting the multiplier can help you fine-tune the Lora model's influence on different aspects of the generated image.

By following these tips and experimenting with different weight and multiplier values, you can effectively utilize Lora models in image generation to achieve the desired styles and features in your AI-generated images.
