# Metal

This page covers how to use [Metal](https://getmetal.io) 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](https://app.getmetal.io/signup).

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.

```python
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")
```

Batch update of alt text and title attributes for images in md/mdx files across repo (#15357) Description: Batch update of alt text and title attributes for images in `md` & `mdx` files across the repo using [alttexter](https://github.com/jonathanalgar/alttexter)/[alttexter-ghclient](https://github.com/jonathanalgar/alttexter-ghclient) (built using LangChain/LangSmith). Limitation: cannot update `ipynb` files because of [this issue](https://github.com/langchain-ai/langchain/pull/15357#issuecomment-1885037250). Can revisit when Docusaurus is bumped to v3. I checked all the generated alt texts and titles and didn't find any technical inaccuracies. That's not to say they're _perfect_, but a lot better than what's there currently.
