# 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)
## Text Embedding Model
See a [usage example](https://python.langchain.com/docs/integrations/text_embedding/openai)
```python
from langchain_openai import OpenAIEmbeddings
```
If you are using a model hosted on `Azure`, you should use different wrapper for that:
```python
from langchain_openai import AzureOpenAIEmbeddings
```
For a more detailed walkthrough of the `Azure` wrapper, see [AzureOpenAIEmbeddings](https://python.langchain.com/docs/integrations/text_embedding/azureopenai)
## LLM (Legacy)
LLM refers to the legacy text-completion models that preceded chat models. See a [usage example](https://python.langchain.com/docs/integrations/llms/openai).
```python
from langchain_openai import OpenAI
```
If you are using a model hosted on `Azure`, you should use different wrapper for that:
```python
from langchain_openai import AzureOpenAI
```
For a more detailed walkthrough of the `Azure` wrapper, see [Azure OpenAI](https://python.langchain.com/docs/integrations/llms/azure_openai)
