# Ollama

Create, run, and share self-contained large language models (LLMs). Ollama bundles a model’s weights, configuration, prompts, and more into self-contained packages that run anywhere.

> Note: Ollama is in early preview. Please report any issues you find.

## Download

- [Download](https://ollama.ai/download) for macOS on Apple Silicon (Intel coming soon)
- Download for Windows and Linux (coming soon)
- Build [from source](#building)

## Examples

### Quickstart

```
ollama run llama2
>>> hi
Hello! How can I help you today?
```

### Creating a custom model

Create a `Modelfile`:

```
FROM llama2
PROMPT """
You are Mario from Super Mario Bros. Answer as Mario, the assistant, only.

User: {{ .Prompt }}
Mario:
"""
```

Next, create and run the model:

```
ollama create mario -f ./Modelfile
ollama run mario
>>> hi
Hello! It's your friend Mario.
```

## Model library

Ollama includes a library of open-source, pre-trained models. More models are coming soon.
