By using this node, you can expect to produce images with improved clarity and detail, making it an essential tool for advanced AI art creation.

Mikey Sampler Base Only Advanced Input Parameters:

base_model

This parameter specifies the model to be used for the sampling process. It is crucial as it determines the underlying architecture and capabilities of the sampler. The model should be chosen based on the desired output quality and the specific requirements of your project.

positive_cond_base

This parameter allows you to input positive conditioning data, which helps guide the sampler towards generating desired features in the output image. It is essential for emphasizing specific characteristics or styles in the generated art.

negative_cond_base

This parameter is used to input negative conditioning data, which helps the sampler avoid certain features or styles in the output image. It is useful for refining the output by excluding unwanted elements.

samples

This parameter represents the latent samples that the node will process. These samples are the initial data points that the sampler will refine to produce the final image.

vae

This parameter specifies the Variational Autoencoder (VAE) to be used in the sampling process. The VAE plays a critical role in encoding and decoding the latent samples, impacting the overall quality of the generated image.

add_noise

This parameter allows you to enable or disable the addition of noise during the sampling process. Adding noise can help in generating more diverse and creative outputs. The default value is "enable".

denoise

This parameter controls the level of denoising applied to the samples. It ranges from 0.0 to 1.0, with a default value of 1.0. Higher values result in smoother images, while lower values retain more detail.

steps

This parameter sets the number of steps for the sampling process. It ranges from 1 to 1000, with a default value of 31. More steps generally lead to higher quality images but require more computational resources.

smooth_step

This parameter controls the smoothness of the steps in the sampling process. It ranges from -1 to 100, with a default value of 0. Adjusting this can help in achieving a balance between smoothness and detail.

cfg_1

This parameter is a configuration setting that influences the sampling process. It ranges from 0.1 to 100.0, with a default value of 5.0. It allows for fine-tuning of the sampler's behavior to achieve the desired output.

cfg_2

This parameter is another configuration setting that impacts the sampling process. It ranges from 0.1 to 100.0, with a default value of 9.5. It provides additional control over the sampler's performance.

sampler_name

This parameter allows you to select the specific sampler algorithm to be used. The default value is "dpmpp_3m_sde_gpu". Different algorithms can produce varying results, so choosing the right one is important for your project.

scheduler

This parameter specifies the scheduler to be used in the sampling process. The default value is "exponential". The scheduler influences the timing and sequence of the sampling steps.

upscale_model

This parameter allows you to specify the model to be used for upscaling the generated image. Upscaling can enhance the resolution and detail of the final output.

seed

This parameter sets the seed value for the random number generator used in the sampling process. It ranges from 0 to 0xffffffffffffffff, with a default value of 0. Setting a specific seed can help in reproducing the same results.

upscale_by

This parameter controls the factor by which the generated image is upscaled. It ranges from 0.0 to 10.0, with a default value of 1.0. Higher values result in larger images with more detail.

hires_denoise

This parameter sets the level of denoising applied during the high-resolution phase of the sampling process. It ranges from 0.0 to 1.0, with a default value of 0.4. Adjusting this can help in achieving a balance between detail and smoothness in high-resolution images.

Mikey Sampler Base Only Advanced Output Parameters:

samples

The output parameter "samples" represents the refined latent samples that have been processed by the node. These samples are the final data points that can be decoded to produce the high-quality generated image. The quality and detail of these samples are influenced by the input parameters and the specific settings used during the sampling process.

Mikey Sampler Base Only Advanced Usage Tips:

• Experiment with different values for the denoise parameter to find the right balance between smoothness and detail in your images.
• Use the add_noise parameter to introduce variability and creativity in your outputs, especially when generating multiple images.
• Adjust the steps parameter to control the quality of the final image; more steps generally lead to better results but require more computational power.
• Fine-tune the cfg_1 and cfg_2 parameters to optimize the sampler's performance for your specific project needs.

Mikey Sampler Base Only Advanced Common Errors and Solutions:

"Invalid model specified"
