Introduction

java-langchains aims to provide a Java native alternative to hwchase17/langchain. As such this project tries to empower user's to create modular and composable LLM applications.

Chains

Modular components implement the Chain interface. This provides an easy way to modularize the application and encouraging reuse for various use cases.

Getting Started

First add one of our built versions as a maven dependency (for further information see Installation). After that you can follow the Quickstart which demonstrates basic chain usage. For details about the concept of Chains as well as detailed information for different parts of this project check out the packages section.
