# Remembrall
|
||
|
|
|
||
|
|
This page covers how to use the [Remembrall](https://remembrall.dev) ecosystem within LangChain.
|
||
|
|
|
||
|
|
## What is Remembrall?
|
||
|
|
|
||
|
|
Remembrall gives your language model long-term memory, retrieval augmented generation, and complete observability with just a few lines of code.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
It works as a light-weight proxy on top of your OpenAI calls and simply augments the context of the chat calls at runtime with relevant facts that have been collected.
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
To get started, [sign in with Github on the Remembrall platform](https://remembrall.dev/login) and copy your [API key from the settings page](https://remembrall.dev/dashboard/settings).
|
||
|
|
|
||
|
|
Any request that you send with the modified `openai_api_base` (see below) and Remembrall API key will automatically be tracked in the Remembrall dashboard. You **never** have to share your OpenAI key with our platform and this information is **never** stored by the Remembrall systems.
|
||
|
|
|
||
|
|
### Enable Long Term Memory
|
||
|
|
|
||
|
|
In addition to setting the `openai_api_base` and Remembrall API key via `x-gp-api-key`, you should specify a UID to maintain memory for. This will usually be a unique user identifier (like email).
|
||
|
|
|
||
|
|
```python
|
||
|
|
from langchain.chat_models import ChatOpenAI
|
||
|
|
chat_model = ChatOpenAI(openai_api_base="https://remembrall.dev/api/openai/v1",
|
||
|
|
model_kwargs={
|
||
|
|
"headers":{
|
||
|
|
"x-gp-api-key": "remembrall-api-key-here",
|
||
|
|
"x-gp-remember": "user@email.com",
|
||
|
|
}
|
||
|
|
})
|
||
|
|
|
||
|
|
chat_model.predict("My favorite color is blue.")
|
||
|
|
import time; time.sleep(5) # wait for system to save fact via auto save
|
||
|
|
print(chat_model.predict("What is my favorite color?"))
|
||
|
|
```
|
||
|
|
|
||
|
|
### Enable Retrieval Augmented Generation
|
||
|
|
|
||
|
|
First, create a document context in the [Remembrall dashboard](https://remembrall.dev/dashboard/spells). Paste in the document texts or upload documents as PDFs to be processed. Save the Document Context ID and insert it as shown below.
|
||
|
|
|
||
|
|
```python
|
||
|
|
from langchain.chat_models import ChatOpenAI
|
||
|
|
chat_model = ChatOpenAI(openai_api_base="https://remembrall.dev/api/openai/v1",
|
||
|
|
model_kwargs={
|
||
|
|
"headers":{
|
||
|
|
"x-gp-api-key": "remembrall-api-key-here",
|
||
|
|
"x-gp-context": "document-context-id-goes-here",
|
||
|
|
}
|
||
|
|
})
|
||
|
|
|
||
|
|
print(chat_model.predict("This is a question that can be answered with my document."))
|
||
|
|
```
