# Ollama plugin
The Ollama plugin provides interfaces to any of the local LLMs supported by
[Ollama](https://ollama.com/).
## Prerequisites
This plugin requires that you first install and run the Ollama server. You can
follow the instructions on the [Download Ollama](https://ollama.com/download)
page.
Use the Ollama CLI to download the models you are interested in. For example:
```posix-terminal
ollama pull gemma2
```
For development, you can run Ollama on your development machine. Deployed apps
usually run Ollama on a different, GPU-accelerated, machine from the app backend
that runs Genkit.
## Configuration
To use this plugin, call `ollama.Init()`, specifying the address of your Ollama
server:
```go
import "github.com/firebase/genkit/go/plugins/ollama"
```
```golang
{% includecode github_path="firebase/genkit/go/internal/doc-snippets/ollama.go" region_tag="init" adjust_indentation="auto" %}
```
## Usage
To generate content, you first need to create a model definition based on the
model you installed and want to use. For example, if you installed Gemma 2:
```golang
{% includecode github_path="firebase/genkit/go/internal/doc-snippets/ollama.go" region_tag="definemodel" adjust_indentation="auto" %}
```
Then, you can use the model reference to send requests to your Ollama server:
```golang
{% includecode github_path="firebase/genkit/go/internal/doc-snippets/ollama.go" region_tag="gen" adjust_indentation="auto" %}
```
See [Generating content](models.md) for more information.
