Add local AI features to Unreal Engine projects. Build AI dialogue, assistants, multimodal interactions, and tool-driven gameplay systems from Blueprint or C++.

LiteRT-LM Edge AI for Unreal Engine helps you bring local LLM-powered features into your Unreal projects without depending on a cloud AI service.

Use it to create smarter NPC dialogue, in-game assistants, AI-powered tools, prototype workflows, interactive characters, image-aware gameplay features, and privacy-conscious AI experiences that can run with compatible local model files.

Main Features

Local AI for Unreal Engine

Run compatible local model files directly in your Unreal project workflow.

Text generation

Stream generated text for dialogue, assistants, chat interfaces, and gameplay responses.

Blueprint and C++ support

Build AI features visually in Blueprint or integrate them directly in native C++.

Multimodal interactions

Send prompts together with local image and audio file paths for supported multimodal models.

Conversation support

Create multi-turn AI conversations for characters, tools, assistants, and interactive systems.

Tool calling workflow

Let the AI request actions from your game or application, then return the results back into the conversation.

Async workflow

Use callback-based async actions designed for Unreal gameplay integration.

Use Cases

NPC dialogue and character interaction

Local AI assistants inside editor tools or runtime apps

AI-powered gameplay prototypes

Image-aware interactions and analysis

Offline or privacy-conscious AI experiences

Tool-using agents connected to your own gameplay logic

Important Notes

Compatible LiteRT-LM model files are required.

Models are not included with this plugin.

Multimodal input currently uses local file paths. It does not directly accept UTexture2D or USoundWave objects.

Performance and feature support depend on the model, target hardware, and selected runtime configuration.
