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.
