How to Fine-Tune Llama 3 on an NVIDIA A100 GPU Server




Meta’s Llama 3 is one of the most powerful open-source Large Language Models (LLMs) available today. However, out of the box, it is a general-purpose model. To make it perform specific enterprise tasks — such as generating accurate medical reports, coding in a proprietary language, or acting as a highly specialized customer support agent — you need to fine-tune it on your own dataset.

Fine-tuning an LLM requires massive computational power and high-bandwidth memory. The NVIDIA A100 (80GB VRAM) is the industry-standard GPU for this task. Deploying this on a bare-metal dedicated server ensures you don’t face the throttling or hidden egress fees common with shared cloud GPUs.

In this tutorial, we will show you how to fine-tune the Llama 3 (8B) model using QLoRA (Quantized Low-Rank Adaptation) on an Ubuntu 24.04 LTS bare-metal NVIDIA A100 server
