# Nebula

This page covers how to use [Nebula](https://symbl.ai/nebula), [Symbl.ai](https://symbl.ai/)'s LLM, ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Nebula wrappers.

## Installation and Setup

- Get an [Nebula API Key](https://info.symbl.ai/Nebula_Private_Beta.html) and set as environment variable `NEBULA_API_KEY`
- Please see the [Nebula documentation](https://docs.symbl.ai/docs/nebula-llm) for more details.
- No time? Visit the [Nebula Quickstart Guide](https://docs.symbl.ai/docs/nebula-quickstart).

### LLM

There exists an Nebula LLM wrapper, which you can access with
```python
from langchain.llms import Nebula
llm = Nebula()
```
