ComfyUI VRAM Tracker: Visualizes Model Memory Lifecycle
Puppet_Master_1337 · reddit · 2026-08-02
A developer has open-sourced a ComfyUI VRAM Tracker node that tracks the full memory lifecycle during a ComfyUI run. It logs when weights are reserved, paged into VRAM, computed on, evicted, and freed.
The tool renders an interactive HTML report featuring a timeline and search functionality for specific layers. This allows developers to visually inspect model allocation, identify VRAM-saturating layers, and fine-tune quantization strategies. It supports both AMD and NVIDIA GPUs, working best with ComfyUI's memory manager enabled.
