Implements Chain-of-Note as described in https://arxiv.org/pdf/2311.09210.pdf by Yu, et al. Uses Wikipedia for retrieval.
Check out the prompt being used here https://smith.langchain.com/hub/bagatur/chain-of-note-wiki.
Environment Setup
Uses Anthropic claude-3-sonnet-20240229 chat model. Set Anthropic API key:
export ANTHROPIC_API_KEY="..."
Usage
To use this package, you should first have the LangChain CLI installed:
pip install -U "langchain-cli[serve]"
To create a new LangChain project and install this as the only package, you can do:
langchain app new my-app --package chain-of-note-wiki
If you want to add this to an existing project, you can just run:
langchain app add chain-of-note-wiki
And add the following code to your server.py file:
from chain_of_note_wiki import chain as chain_of_note_wiki_chain
add_routes(app, chain_of_note_wiki_chain, path="/chain-of-note-wiki")
(Optional) Let's now configure LangSmith. LangSmith will help us trace, monitor and debug LangChain applications. LangSmith is currently in private beta, you can sign up here. If you don't have access, you can skip this section
export LANGCHAIN_TRACING_V2=true
export LANGCHAIN_API_KEY=<your-api-key>
export LANGCHAIN_PROJECT=<your-project> # if not specified, defaults to "default"
If you are inside this directory, then you can spin up a LangServe instance directly by:
langchain serve
This will start the FastAPI app with a server is running locally at http://localhost:8000
We can see all templates at http://127.0.0.1:8000/docs We can access the playground at http://127.0.0.1:8000/chain-of-note-wiki/playground
We can access the template from code with:
from langserve.client import RemoteRunnable
runnable = RemoteRunnable("http://localhost:8000/chain-of-note-wiki")
