IPAdapter Unified Loader FaceID V2 Input Parameters:

model

The model parameter specifies the model to be used for face identification. It is a required input and serves as the foundation for the node's operations. The model determines the underlying architecture and capabilities of the face identification process, influencing the accuracy and efficiency of the results.

preset

The preset parameter allows you to choose from a selection of predefined configurations tailored for different face identification tasks. Options include FACEID, `FACEID PLUS

• SD1.5 only, FACEID PLUS V2, FACEID PORTRAIT (style transfer), and FACEID PORTRAIT UNNORM - SDXL only (strong)`. Each preset is optimized for specific scenarios, such as standard face ID, enhanced face ID for certain Stable Diffusion versions, or style transfer applications. This parameter helps streamline the setup process by providing configurations that are ready to use for specific tasks.

lora_strength

The lora_strength parameter controls the strength of the LoRA (Low-Rank Adaptation) applied to the model. It is a float value with a default of 0.6, a minimum of 0, and a maximum of 1, adjustable in steps of 0.01. This parameter influences the degree of adaptation applied to the model, affecting the balance between the original model's characteristics and the adapted features. Adjusting this value allows for fine-tuning the model's performance to better suit specific face identification tasks.

provider

The provider parameter specifies the computational provider to be used for executing the model. Options include CPU, CUDA, ROCM, DirectML, OpenVINO, and CoreML. This parameter determines the hardware on which the model will run, impacting the speed and efficiency of the face identification process. Selecting the appropriate provider ensures optimal performance based on the available hardware resources.

ipadapter

The ipadapter parameter is an optional input that allows you to specify an IPAdapter instance to be used in conjunction with the model. This parameter provides additional flexibility by enabling the integration of custom IPAdapter configurations, which can enhance the model's capabilities or tailor its performance to specific requirements.
