# Ollama

[![Discord](https://dcbadge.vercel.app/api/server/ollama?style=flat&compact=true)](https://discord.gg/ollama)

Get up and running with large language models locally.

### macOS

[Download](https://ollama.ai/download/Ollama-darwin.zip)

### Windows

Coming soon!

### Linux & WSL2

```
curl https://ollama.ai/install.sh | sh
```

[Manual install instructions](https://github.com/jmorganca/ollama/blob/main/docs/linux.md)

### Docker

See the official [Docker image](https://hub.docker.com/r/ollama/ollama).

## Quickstart

To run and chat with [Llama 2](https://ollama.ai/library/llama2):

```
ollama run llama2
```

## Model library

Ollama supports a list of open-source models available on [ollama.ai/library](https://ollama.ai/library 'ollama model library')

Here are some example open-source models that can be downloaded:

| Model              | Parameters | Size  | Download                       |
| ------------------ | ---------- | ----- | ------------------------------ |
| Mistral            | 7B         | 4.1GB | `ollama run mistral`           |
| Llama 2            | 7B         | 3.8GB | `ollama run llama2`            |
| Code Llama         | 7B         | 3.8GB | `ollama run codellama`         |
| Llama 2 Uncensored | 7B         | 3.8GB | `ollama run llama2-uncensored` |
| Llama 2 13B        | 13B        | 7.3GB | `ollama run llama2:13b`        |
| Llama 2 70B        | 70B        | 39GB  | `ollama run llama2:70b`        |
| Orca Mini          | 3B         | 1.9GB | `ollama run orca-mini`         |
| Vicuna             | 7B         | 3.8GB | `ollama run vicuna`            |

> Note: You should have at least 8 GB of RAM to run the 3B models, 16 GB to run the 7B models, and 32 GB to run the 13B models.

## Customize your own model

### Import from GGUF

Ollama supports importing GGUF models in the Modelfile:

1. Create a file named `Modelfile`, with a `FROM` instruction with the local filepath to the model you want to import.

   ```
   FROM ./vicuna-33b.Q4_0.gguf
   ```

2. Create the model in Ollama

   ```
   ollama create example -f Modelfile
   ```

3. Run the model

   ```
   ollama run example
   ```

### Import from PyTorch or Safetensors

See the [guide](docs/import.md) on importing models for more information.

### Customize a prompt

Models from the Ollama library can be customized with a prompt. The example

```
ollama pull llama2
```

Create a `Modelfile`:

```
FROM llama2

# set the temperature to 1 [higher is more creative, lower is more coherent]
PARAMETER temperature 1

# set the system prompt
SYSTEM """
You are Mario from Super Mario Bros. Answer as Mario, the assistant, only.
"""
```

Next, create and run the model:

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

For more examples, see the [examples](examples) directory. For more information on working with a Modelfile, see the [Modelfile](docs/modelfile.md) documentation.

## CLI Reference

### Create a model

`ollama create` is used to create a model from a Modelfile.

### Pull a model

```
ollama pull llama2
```

> This command can also be used to update a local model. Only the diff will be pulled.

### Remove a model

```
ollama rm llama2
```

### Copy a model

```
ollama cp llama2 my-llama2
```

### Multiline input

For multiline input, you can wrap text with `"""`:

```
>>> """Hello,
... world!
... """
I'm a basic program that prints the famous "Hello, world!" message to the console.
```

### Pass in prompt as arguments

```
$ ollama run llama2 "summarize this file:" "$(cat README.md)"
 Ollama is a lightweight, extensible framework for building and running language models on the local machine. It provides a simple API for creating, running, and managing models, as well as a library of pre-built models that can be easily used in a variety of applications.
```

### List models on your computer

```
ollama list
```

### Start Ollama

`ollama serve` is used when you want to start ollama without running the desktop application.

## Building

Install `cmake` and `go`:

```
brew install cmake
brew install go
```

Then generate dependencies and build:

```
go generate ./...
go build .
```

Next, start the server:

```
./ollama serve
```

Finally, in a separate shell, run a model:

```
./ollama run llama2
```

## REST API

> See the [API documentation](docs/api.md) for all endpoints.

Ollama has an API for running and managing models. For example to generate text from a model:

```
curl -X POST http://localhost:11434/api/generate -d '{
  "model": "llama2",
  "prompt":"Why is the sky blue?"
}'
```
