Metal

This page covers how to use Metal within LangChain.

What is Metal?

Metal is a managed retrieval & memory platform built for production. Easily index your data into Metal and run semantic search and retrieval on it.

Quick start

Get started by creating a Metal account.

Then, you can easily take advantage of the MetalRetriever class to start retrieving your data for semantic search, prompting context, etc. This class takes a Metal instance and a dictionary of parameters to pass to the Metal API.

from langchain.retrievers import MetalRetriever
from metal_sdk.metal import Metal


metal = Metal("API_KEY", "CLIENT_ID", "INDEX_ID");
retriever = MetalRetriever(metal, params={"limit": 2})

docs = retriever.invoke("search term")
