How to Run Llama 2 Locally on Your Mac or PC Using Llama.cpp

Llama.cpp is a C/C++ port of Llama that makes it possible on how to run Llama 2 locally with 4-bit integer quantization on Macs, Windows, and Linux machines using 4-bit integer quantization. Created by Gerganov Gerganov – an AI enthusiast and software engineer. Llama uses Metal API computation on GPU to improve performance while decreasing memory usage; supporting both Llama 2, as well as Llama 1 GPT-3 Neo.

To use Llama.cpp on either Mac or PC devices, a compatible device and basic knowledge of terminal commands are necessary for the installation and usage of this program. Here are steps for doing just this on either platform:

Step 1: Check the System Requirements

Before you install Llama.cpp, you need to make sure that your device meets the minimum system requirements. Here are the system requirements for different operating systems:

Mac: Any Mac with an Apple M1 or M2 chip, or a 2nd generation Intel Core or newer with support for Hypervisor Framework. You also need to have Xcode installed.
Windows: Any Windows machine with a x86_64 CPU architecture, a 2nd generation Intel Core or newer, or an AMD CPU with support for a Windows Hypervisor Framework. You also need to have Visual Studio 2019 installed.
Linux: Any Linux machine with a x86_64 CPU architecture, a 2nd generation Intel Core or newer, or an AMD processor with support for AMD Virtualization (AMD-V) and SSSE3. You also need to have GCC 10 or newer installed.

Step 2: Download and Build Llama.cpp

Step two is downloading and building Llama.cpp from its GitHub repository, using one or both of these commands in either terminal or command prompt, depending on your operating system:

Mac: curl -L "https://replicate.fyi/install-llama-cpp" | bash
Windows: curl -L "https://replicate.fyi/windows-install-llama-cpp" | bash
Linux: curl -L "https://replicate.fyi/install-llama-cpp-cpu" | bash

These commands will clone and build the Llama.cpp repository, build its executable file, and download its Llama 2 model – approximately 7.3GB in size – although downloading may take some time depending on internet speeds and whether or not a different MODEL file exists (you can change this variable via command-line options). You may also select your model file by changing MODEL variable within commands.

Step 3: Run Llama.cpp and Chat with Llama 2

The final step is to run Llama.cpp and chat with Llama 2. You can use the following command in your terminal or command prompt:

./main -m ./models/llama-2-13b-chat.ggmlv3.q4_0.bin --color --ctx_size 2048 -n -1 -ins -b 256 --top_k 10000 --temp 0.2 --repeat_penalty 1.1 -t 8

This command will launch Llama.cpp interactively using the Llama 2 chat model and allow you to adjust its parameters according to your personal tastes; for instance, by changing temperature, top_k, and repeat_penalty you can control randomness, diversity, and repetition in generated texts as well as set length of context window by altering ctx_size value. For more details on the parameters, you can check the Llama.cpp README file.

Once Llama.cpp is running, simply type your message and press Enter to send it directly to Llama 2. Llama 2 will respond with its generated text; converse with him about topics like concepts, poems, code puzzles or pet names (here’s an example conversation between humans and Llama 2) Here is an example dialogue with Llama 2:

>>> Hi, Llama 2!
Hello! I'm Llama 2, a large language model that can generate natural language, code, images, and more. How can I help you today?
>>> Can you write a poem about llamas?
Sure, I can try to write a poem about llamas. Here is what I came up with:

Llamas are amazing creatures
They have long necks and funny features
They live in the mountains of South America
And they can spit when they feel panica

Llamas are gentle and friendly animals
They like to graze on grass and minerals
They can carry heavy loads on their backs
And they can protect themselves from attacks

Llamas are smart and curious beings
They have expressive eyes and ears
They can communicate with humming sounds
And they can bond with humans and hounds

Llamas are wonderful and majestic
They are fluffy and fantastic
They are more than just a meme
They are a poet's dream
