I have a question regarding the VRAM requirements for fine-tuning a 7B model.

Author: mangyeongCreated Jan 15, 2025Updated Dec 22, 2025

In the README on GitHub, it states: "Addressing OOM - Naively, fine-tuning a 7B model requires about 7 x 4 x 4 = 112 GB of VRAM." Could you please explain in detail how this calculation is derived?
