The world of Large Language Models (LLMs) has seen rapid advancements, with models like GPT and LLaMA pushing the boundaries of what is possible in natural language understanding and generation. However, running these models efficiently often requires significant computational resources, typically in the form of high-performance GPUs. Yet, not everyone has access to such hardware, and there are scenarios where running LLMs on CPUs is not only feasible but also preferable. This blog provides a detailed, step-by-step guide on how to run LLaMA and other LLMs on CPUs using various libraries and optimization techniques.

1. Introduction

Running LLMs like LLaMA on CPUs presents both challenges and opportunities. CPUs are ubiquitous and offer a cost-effective alternative to GPUs, especially for development, testing, and certain production environments. While CPUs cannot match the raw processing power of GPUs, they can still be utilized effectively with the right optimizations.

In this guide, we’ll explore all the available options, tools, and libraries to help you run LLMs on CPUs, focusing on LLaMA as a case study.

2. Why Run LLMs on CPUs?
