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
