Overview

Langchain-hs is a Haskell port of the LangChain framework, enabling Haskell developers to build and integrate language model applications. It provides Haskell-specific bindings and utilities for leveraging large language models (LLMs) in functional programming workflows.

Problem It Solves

It allows Haskell developers to use LangChain's capabilities without relying on Python or other language ecosystems, bridging the gap between functional programming and modern AI tooling.

Target Audience: Developers and teams working with ports to other languages automation.
