# Ollama

![](https://ollama.com/public/ollama.png)

[Ollama](https://ollama.com/) is deployed in ExCL as a module. To use Ollama, load the module, and then you have access to the `ollama` CLI interface.

Load the Ollama module with:

```bash
module load ollama
```

Ollama has a server component which stores files in its home. This server component should be launched using a service account by ExCL admin, since it provides ollama for the entire system. Ollama is already running on some of the workers in ExCL. See the output from the model load for an up-to-date list. Contact <excl-help@ornl.gov> if you would like ollama to be available on a specific system.

## Ollama API

{% hint style="warning" %}
When interacting with the Ollama server via the [REST API](https://github.com/ollama/ollama?tab=readme-ov-file#rest-api) in ExCL, you need to unset the `http_proxy` and `https_proxy` environment variables, since you are trying to connect to an internal http server instead of a remote one.
{% endhint %}

Examples of using the Ollama API can be found at [ollama-python/examples/chat.py](https://github.com/ollama/ollama-python/blob/main/examples/chat.py).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.excl.ornl.gov/quick-start-guides/ollama.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
