Local AI

Introduction

Local AI is a term used to describe the use of AI models on a local device, such as a smartphone or a computer. This is in contrast to cloud-based AI, where the AI model is hosted on a remote server and accessed over the internet. Local AI has several advantages, including improved privacy and reduced latency. However, it also has some limitations, such as limited processing power and storage space.

Install AMD drivers (ROCm)

sudo pacman -S --needed rocm-hip-sdk rocm-opencl-sdk rocm-hip-runtime hip-runtime-amd miopen-hip rocm-opencl-runtime

OpenCL Image support

The latest ROCm versions now includes OpenCL Image Support used by GPGPU accelerated software such as Darktable. ROCm with the AMDGPU open source graphics driver are all that is required. AMDGPU PRO is not required.

❯ /opt/rocm/bin/clinfo | grep -i "image support"
  Image support:				 Yes

LMStudio

LM Studio is a desktop application for running local LLMs on your computer. Install from AUR:

yay -S --needed lmstudio-appimage

Jan AI

Jan is a ChatGPT-alternative that runs 100% offline on your Desktop. Our goal is to make it easy for a person to download and run LLMs and use AI with full control and privacy. Install from AUR:

yay -S --needed jan-bin

Ollama

Ollama is a free and open-source AI assistant that runs locally on your device. It can perform a wide range of tasks, such as answering questions, setting reminders, and playing music.

Install from an official repository:

sudo pacman -S --needed ollama
sudo systemctl enable --now ollama.service

Install from script:

curl -fsSL https://ollama.com/install.sh | sh

Install from source:

Ollama is distributed as a self-contained binary. Download it to a directory in your PATH:

sudo curl -L https://ollama.com/download/ollama-linux-amd64 -o /usr/bin/ollama
sudo chmod +x /usr/bin/ollama

Adding Ollama as a startup service (recommended)

Create a user for Ollama:

sudo useradd -r -s /bin/false -m -d /usr/share/ollama ollama

Create a service file in /etc/systemd/system/ollama.service:

[Unit]
Description=Ollama Service
After=network-online.target

[Service]
ExecStart=/usr/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3

[Install]
WantedBy=default.target

Then start the service:

sudo systemctl daemon-reload
sudo systemctl enable --now ollama

AMD Radeon GPU support

While AMD has contributed the amdgpu driver upstream to the official linux kernel source, the version is older and may not support all ROCm features. We recommend you install the latest driver from AMD Official Website for best support of your Radeon GPU.

Update

Update ollama by running the install script again:

curl -fsSL https://ollama.com/install.sh | sh

Or by downloading the ollama binary:

sudo curl -L https://ollama.com/download/ollama-linux-amd64 -o /usr/bin/ollama
sudo chmod +x /usr/bin/ollama

Installing specific versions

Use OLLAMA_VERSION environment variable with the install script to install a specific version of Ollama, including pre-releases. You can find the version numbers in the releases page.

For example:

curl -fsSL https://ollama.com/install.sh | OLLAMA_VERSION=0.1.32 sh

Viewing logs

To view logs of Ollama running as a startup service, run:

journalctl -e -u ollama

Uninstall

Remove the ollama service:

sudo systemctl stop ollama
sudo systemctl disable ollama
sudo rm /etc/systemd/system/ollama.service

Remove the ollama binary from your bin directory (either /usr/local/bin, /usr/bin, or /bin):

sudo rm $(which ollama)

Remove the downloaded models and Ollama service user and group:

sudo rm -r /usr/share/ollama
sudo userdel ollama
sudo groupdel ollama
