For unloading specific models or all models within ComfyUI, this tool leverages existing memory management features to optimize VRAM usage. It provides two dedicated nodes that facilitate manual model unloading during workflows to enhance performance.
- This tool includes "Unload Model" and "Unload All Models" nodes, designed as passthroughs for efficient memory management.
- It is particularly beneficial for users experiencing slow generation speeds, as it allows for unloading models when they are no longer needed.
- The primary use case involves unloading the CLIP model after obtaining embeddings, which conserves VRAM during sampling, especially when using the Flux diffusion model.
Context
This tool functions as an extension within ComfyUI, aimed at improving memory management by allowing users to unload models at specific points in their workflows. By using this functionality, users can optimize their system's performance, particularly when working with large models that consume significant VRAM.
Key Features & Benefits
The primary features of this tool are the "Unload Model" and "Unload All Models" nodes, which enable users to manually control memory usage. This capability is crucial for maintaining optimal performance, especially in scenarios where multiple models are loaded simultaneously, as it allows users to free up VRAM when certain models are no longer necessary.
Advanced Functionalities
The tool's advanced functionality lies in its ability to unload specific models based on user-defined steps within a workflow. This is particularly useful for users who wish to manage VRAM allocation actively, such as unloading the CLIP model after embedding extraction to make room for other resource-intensive models like the Flux diffusion model.
Practical Benefits
By implementing this tool, users can significantly enhance their workflow efficiency, maintain control over memory usage, and improve generation speeds. It allows for a more streamlined process when switching between models or managing resources, ultimately leading to better performance in ComfyUI.
