{
    if [ $# -ne 3 ]; then
        echo "ERROR: Expected 3 arguments, but only got $#" 1>&2
        return 1

### Podman Volume Locations

`~/.local/share/containers/storage/volumes/`

### List of Internal Links

- llama-cpp
- llama-embed
- llama-instruct
- image-gen
- image-edit
- openwebui

## Quick Install

### Text Stack

```bash
ansible-playbook \
-i ansible/inventory.yaml \
active/software_ai_stack/install_ai_text_stack.yaml
```

### Image Stack

```bash
ansible-playbook \
-i ansible/inventory.yaml \
active/software_ai_stack/install_ai_image_stack.yaml
```

## Setup

### Create the AI user

```bash
# Create your local ai user. This will be the user you launch podman processes from.
useradd -m ai
loginctl enable-linger ai
su -l ai
mkdir -p /home/ai/.config/containers/systemd/
mkdir -p /home/ai/.ssh
```

Models are big. You'll want some tools to help find large files quickly when space runs out.

### Helper aliases

Add these to your .bashrc:

```bash
# Calculate all folder sizes in current dir 
alias {dudir,dud}='du -h --max-depth 1 | sort -h'

# Calculate all file sizes in current dir
alias {dufile,duf}='ls -lhSr'

# Restart llama-server / follow logs
alias llama-reload="systemctl --user daemon-reload && systemctl --user restart llama-server.service"
alias llama-logs="journalctl --user -fu llama-server"

# Restart stable diffusion gen and edit server / follow logs
alias sd-gen-reload='systemctl --user daemon-reload && systemctl --user restart stable-diffusion-gen-server'
alias sd-gen-logs='journalctl --user -xeu stable-diffusion-gen-server'
alias sd-edit-reload='systemctl --user daemon-reload && systemctl --user restart stable-diffusion-edit-server'
alias sd-edit-logs='journalctl --user -xeu stable-diffusion-edit-server'
```

### Create the models dir

```bash
mkdir -p /home/ai/models/{text,image,video,embedding,tts,stt}
```

### Install the Hugging Face CLI

<https://huggingface.co/docs/huggingface_hub/en/guides/cli#getting-started>

```bash
# Install
curl -LsSf https://hf.co/cli/install.sh | bash

# Login
hf auth login
```

### Samba Model Storage

I recommend adding network storage for keeping models offloaded. This mounts a samba share at `/srv/models`.

```bash
dnf install -y cifs-utils

# Add this to /etc/fstab
//driveripper.reeselink.com/smb_models /srv/models cifs _netdev,nofail,uid=1001,gid=1001,credentials=/etc/samba/credentials 0 0

# Then mount
systemctl daemon-reload
mount -a --mkdir
```

Here are some sync commands that I use to keep the samba share in sync with the home directory:

```bash
# Sync models from home dir to the samba share
rsync -av --progress /home/ai/models/ /srv/models/
```

### Download models

In general I try to run 8 bit quantized minimum.

```bash

## Install Services with Quadlets

### Internal and External Pods

These will be used to restrict internet access to our llama.cpp and
stable-diffusion.cpp services while allowing the frontend services to
communicate with those containers.

```bash
scp -r active/software_ai_stack/quadlets_pods/* deskwork-ai:.config/containers/systemd/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user start ai-internal-pod.service ai-external-pod.service
```

### Llama CPP Server (Port 8000)

Installs the llama.cpp server to run our text models.

```bash
scp -r active/software_ai_stack/quadlets_llama_think/* deskwork-ai:.config/containers/systemd/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user restart ai-internal-pod.service
```

### Llama CPP Embedding Server (Port 8001)

Installs the llama.cpp server to run our embedding models

```bash
scp -r active/software_ai_stack/quadlets_llama_embed/* deskwork-ai:.config/containers/systemd/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user restart ai-internal-pod.service
```

### Llama CPP Instruct Server (Port 8002)

Installs the llama.cpp server to run a constant instruct (no thinking) model for quick replies

```bash
scp -r active/software_ai_stack/quadlets_llama_instruct/* deskwork-ai:.config/containers/systemd/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user restart ai-internal-pod.service
```

### Stable Diffusion CPP (Port 1234 and 1235)

Installs the stable-diffusion.cpp server to run our image models.

```bash
scp -r active/software_ai_stack/quadlets_stable_diffusion/* deskwork-ai:.config/containers/systemd/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user restart ai-internal-pod.service
```

### Open Webui (Port 8080)

Installs the open webui frontend.

```bash
scp -r active/software_ai_stack/quadlets_openwebui/* deskwork-ai:.config/containers/systemd/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user restart ai-external-pod.service
```

Note, all services will be available at `host.containers.internal`. So llama.cpp
will be up at `http://host.containers.internal:8000`.

### Install the update script

```bash
# 1. Builds the latest llama.cpp and stable-diffusion.cpp
# 2. Pulls the latest open-webui
# 3. Restarts all services
scp active/software_ai_stack/update-script.sh deskwork-ai:
ssh deskwork-ai
chmod +x update-script.sh
./update-script.sh
```

### Install Guest Open Webui with Start/Stop Services

Optionally install a guest openwebui service.

```bash
scp -r active/software_ai_stack/systemd/. deskwork-ai:.config/systemd/user/
ssh deskwork-ai
systemctl --user daemon-reload
systemctl --user enable open-webui-guest-start.timer
systemctl --user enable open-webui-guest-stop.timer
```

## VLLM

### Run VLLM with Podman

```bash
# 'latest' and 'nightly' are both viable tags
podman run --rm \
--device /dev/kfd \
--device /dev/dri \
-v ~/.cache/huggingface:/root/.cache/huggingface:z \
--env "HF_TOKEN=$HF_TOKEN" \
-p 8010:8000 \
--ipc=host \
docker.io/vllm/vllm-openai-rocm:nightly \
--enable-offline-docs \

# Pick your model

```

## Misc

### Quantizing your own Models

```bash
# Create a scratch dir for downloading models
mkdir scratch && cd scratch

# qwen 3.5 35b
mkdir qwen3.5-35b-a3b && cd qwen3.5-35b-a3b
hf download --local-dir . Qwen/Qwen3.5-35B-A3B

# nemotron cascade
mkdir nemotron-cascade-2-30b-a3b && cd nemotron-cascade-2-30b-a3b
hf download --local-dir . nvidia/Nemotron-Cascade-2-30B-A3B

# Run the full 
podman run -it --rm \
--device=/dev/kfd \

-v $(pwd):/models:z \
--entrypoint /bin/bash \

# Run ./llama-quantize to see available quants
# 7 = q_8
# 18 = q_6_k
# 17 = q_5_k
# 15 = q_4_k

### Qwen3.5 Settings

> We recommend using the following set of sampling parameters for generation

- Non-thinking mode for text tasks: temperature=1.0, top_p=1.00, top_k=20, min_p=0.0, presence_penalty=2.0, repetition_penalty=1.0
- Non-thinking mode for VL tasks: temperature=0.7, top_p=0.80, top_k=20, min_p=0.0, presence_penalty=1.5, repetition_penalty=1.0
- Thinking mode for text tasks: temperature=1.0, top_p=0.95, top_k=20, min_p=0.0, presence_penalty=1.5, repetition_penalty=1.0
- Thinking mode for VL or precise coding (e.g. WebDev) tasks : temperature=0.6, top_p=0.95, top_k=20, min_p=0.0, presence_penalty=0.0, repetition_penalty=1.0

> Please note that the support for sampling parameters varies according to inference frameworks.
