## About Langroid
Langroid, created by researchers from CMU and UW-Madison, lets you set up agents with optional LLMs, vector stores and tools, give them tasks and have them solve problems by exchanging messages, in an actor-inspired multi-agent design. It does not depend on LangChain or other LLM frameworks and works with practically any LLM.

## Install

```
pip install langroid
```
