gputaskman
See what's actually using your GPU memory
gputaskman is a free, open-source GPU task manager that shows what's really using your VRAM. Monitor memory and GPU activity by process, identify local AI models, and inspect estimated model weights, KV cache, and runtime buffers. See when GPU workloads use system RAM, compare usage snapshots, or export JSON for scripting. Built for developers running local LLMs, training models, or debugging GPU performance across Windows, Linux, WSL, and experimental macOS support.

Scott Hanselman from Microsoft just released a pretty useful little open-source tool.
Windows Task Manager can tell you how much GPU memory is being used, but figuring out exactly what's using it isn't always easy.
gputaskman gives you an htop-style view of your GPU, including memory usage by process and insights into which local AI models are loaded, their weights, and estimated KV cache.
It also supports Linux, WSL, and early macOS monitoring.
Worth checking out if you run local LLMs and constantly wonder where all your VRAM went.
