# PromptLayer
|
||
|
|
|
||
|
|
This page covers how to use [PromptLayer](https://www.promptlayer.com) within LangChain.
|
||
|
|
It is broken into two parts: installation and setup, and then references to specific PromptLayer wrappers.
|
||
|
|
|
||
|
|
## Installation and Setup
|
||
|
|
|
||
|
|
If you want to work with PromptLayer:
|
||
|
|
- Install the promptlayer python library `pip install promptlayer`
|
||
|
|
- Create a PromptLayer account
|
||
|
|
- Create an api token and set it as an environment variable (`PROMPTLAYER_API_KEY`)
|
||
|
|
|
||
|
|
## Wrappers
|
||
|
|
|
||
|
|
### LLM
|
||
|
|
|
||
|
|
There exists an PromptLayer OpenAI LLM wrapper, which you can access with
|
||
|
|
```python
|
||
|
|
from langchain.llms import PromptLayerOpenAI
|
||
|
|
```
|
||
|
|
|
||
|
|
To tag your requests, use the argument `pl_tags` when instanializing the LLM
|
||
|
|
```python
|
||
|
|
from langchain.llms import PromptLayerOpenAI
|
||
|
|
llm = PromptLayerOpenAI(pl_tags=["langchain-requests", "chatbot"])
|
||
|
|
```
|
||
|
|
|
||
|
|
This LLM is identical to the [OpenAI LLM](./openai), except that
|
||
|
|
- all your requests will be logged to your PromptLayer account
|
||
|
|
- you can add `pl_tags` when instantializing to tag your requests on PromptLayer
