LangChain4j is an idiomatic, open-source Java library for building LLM-powered applications on the JVM. It offers a unified API over popular LLM providers and vector stores, and makes implementing tool calling (including MCP support), agents and RAG easy. It integrates seamlessly with enterprise Java frameworks like Quarkus and Spring Boot.
This project is a WIP of a Nintendo Entertainment System (NES) emulator developed in Java. The goal is to replicate the functionality of the NES hardware in software, allowing classic games to run on modern platforms.
