# Simple Ollama hosting

We have a small 2x A100 (40GB) server w/ a 100% uptime Ollama instance. <br>

* Ollama [Rest API Docs](https://github.com/ollama/ollama/blob/main/docs/api.md)<br>
* Ollama [Python API Docs](https://github.com/ollama/ollama-python)&#x20;

{% hint style="danger" %}
This service is no longer publicly available. It's being used in production for UIUC.chat. For stability, we cannot allow arbitrary use.
{% endhint %}

{% hint style="warning" %}
**Only use `llama3.1:70b` and `nomic-embed-text:v1.5`**\
\
Requesting any other model will cause "thrashing" since there's not enough GPU memory and nobody's jobs will complete. Do not /pull new models.
{% endhint %}

### Examples

#### Llama3 70b-instruct

```bash
# bash
curl https://ollama.ncsa.ai/api/chat -d '{
  "model": "llama3.1:70b",
  "messages": [
    { "role": "user", "content": "Write a long detailed bash program" }
  ]
}'

# python 
from ollama import Client

client = Client(host='https://ollama.ncsa.ai')
response = client.chat(model='llama3.1:70b', messages=[
    {
        'role': 'user',
        'content': 'Why is the sky blue?',
    },
])
```

#### Text embeddings

```bash
# bash
curl https://ollama.ncsa.ai/api/embeddings -d '{
  "model": "nomic-embed-text:v1.5",
  "prompt": "The sky is blue because of Rayleigh scattering"
}'

# python 
from ollama import Client

client = Client(host='https://ollama.ncsa.ai')
client.embeddings(model='nomic-embed-text:v1.5', prompt='The sky is blue because of rayleigh scattering')
```

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.ncsa.ai/simple-ollama-hosting.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.
