Overview

Android Edge AI Runtime for Unity enables Unity Android projects to run compatible GGUF-format local language models directly on the Android device.

Unity C# communicates with a native llama.cpp-based runtime through the included native shim. Local inference runs inside the Android application without requiring an HTTP server, WebSocket server, Python environment, or cloud service.

The package includes:

• A minimal Android chat sample scene

• Unity C# runtime components

• Android arm64-v8a native libraries

• UTF-8-safe multilingual text handling

• Automatic chat-template application for compatible models

• Single-flight generation control to prevent overlapping inference requests

• Runtime and model configuration options

• Setup and model-placement documentation

• Third-party license notices

GGUF model files are not included. Developers select and place their own compatible GGUF model on the Android device.

This package is intended for developers building:

• Offline-capable AI applications

• Interactive characters and virtual agents

• Local AI prototypes

• Robotics interfaces

• Edge AI demonstrations and experiments

• Unity applications that require on-device language-model inference

Requirements and limitations:

• Android only

• arm64-v8a only

• IL2CPP scripting backend required

• CPU inference backend

• Inference must be tested on an Android device

• Unity Editor inference is not supported

• Performance and memory usage depend on the Android device, model architecture, model size, quantization, context size, and runtime settings

• Compatibility with every GGUF model is not guaranteed

Third-party software:

This package uses llama.cpp and ggml under the MIT License, and LLVM libc++ under the Apache License 2.0 with LLVM Exceptions.
