Run a 70B FP16 Model on a Single 16 GB GPU with PyTorch Meta Device

This article explains how to overcome GPU memory limits by using PyTorch 1.9's meta device to create an empty model, load large‑scale model weights layer‑by‑layer, move each part to a 16 GB GPU for inference, and release memory, enabling a 70B FP16 model to run on a single consumer‑grade GPU.
