# Downloading Models
The `llama` CLI tool helps you setup and use the Llama Stack. It should be available on your path after installing the `llama-stack` package.
## Installation
You have two ways to install Llama Stack:
1. **Install as a package**:
You can install the repository directly from [PyPI](https://pypi.org/project/llama-stack/) by running the following command:
```bash
pip install llama-stack
```
2. **Install from source**:
If you prefer to install from the source code, follow these steps:
```bash
mkdir -p ~/local
cd ~/local
git clone git@github.com:meta-llama/llama-stack.git
conda create -n myenv python=3.10
conda activate myenv
cd llama-stack
$CONDA_PREFIX/bin/pip install -e .
## Downloading models via CLI
You first need to have models downloaded locally.
To download any model you need the **Model Descriptor**.
This can be obtained by running the command
```
llama model list
```
You should see a table like this:
```
+----------------------------------+------------------------------------------+----------------+

```
To download models, you can use the llama download command.
#### Downloading from [Meta](https://llama.meta.com/llama-downloads/)
Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/)
Download the required checkpoints using the following commands:
```bash
# download the 8B model, this can be run on a single GPU
llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL
# you can also get the 70B model, this will require 8 GPUs however
llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL
# llama-agents have safety enabled by default. For this, you will need
# safety models -- Llama-Guard and Prompt-Guard
llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL
llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL
```
#### Downloading from [Hugging Face](https://huggingface.co/meta-llama)
Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`.
```bash
llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original*
llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original*
```
**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored.
