## What it is
LLMUnity is an open-source Unity plugin that runs large language models locally in Unity games via llama.cpp, enabling AI-driven characters and NPCs without external APIs. It supports local, offline inference with features like RAG, chat interfaces, and easy setup for game developers.

## Use cases
- add AI-powered NPC dialogue to a Unity game
- run LLMs locally offline in a game engine
- create conversational characters in Unity
- build a chatbot NPC without OpenAI API costs
- add retrieval-augmented generation to game characters
- integrate llama.cpp models into Unity

## When to choose
- you need local, offline LLM inference inside Unity
- you want free, open-source AI characters without API wrappers
- you're building NPC dialogue or conversational AI in a Unity game

## When to avoid
- your project is not built with Unity
- you need cloud-hosted or server-side LLM inference
- you need fine-grained control over llama.cpp beyond the plugin's API
