# langchain-openai
|
|
|
|
This package contains the LangChain integrations for OpenAI through their `openai` SDK.
|
|
|
|
## Installation and Setup
|
|
|
|
- Install the LangChain partner package
|
|
|
|
```bash
|
|
pip install langchain-openai
|
|
```
|
|
|
|
- Get an OpenAI api key and set it as an environment variable (`OPENAI_API_KEY`)
|
|
|
|
## Chat model
|
|
|
|
See a [usage example](https://python.langchain.com/docs/integrations/chat/openai).
|
|
|
|
```python
|
|
from langchain_openai import ChatOpenAI
|
|
```
|
|
|
|
If you are using a model hosted on `Azure`, you should use different wrapper for that:
|
|
|
|
```python
|
|
from langchain_openai import AzureChatOpenAI
|
|
```
|
|
|
|
For a more detailed walkthrough of the `Azure` wrapper, see [AzureChatOpenAI](https://python.langchain.com/docs/integrations/chat/azure_chat_openai)

|
|
