Local, On-Device LLM for NPCs - Dialogue and Intelligence - GladeCore

GladeCore is a comprehensive system for integrating advanced, AI-driven interactions directly into your Unity projects. It lets players hold dynamic, unscripted conversations with NPCs through text or voice. NPCs respond in real time, with personalities, knowledge, and voices defined entirely by easy-to-use assets configured in engine, with no external services required.

Core Features:

• LLM-Powered Dialogue: Local LLM inference to generate dynamic NPC responses
• Zero per Interaction Cost and Low Latency: Runs fully offline - infinitely scalable with no per-use fees
• Speech-to-Text (STT): Players can talk naturally to NPCs via microphone
• Text-to-Speech (TTS): NPCs can respond aloud using ElevenLabs API or local Spark TTS
• Data-Driven Personalities: Define NPC backstories and personality through in editor assets - no code changes required

Why use GladeCore?

GladeCore is the only AI NPC solution built by game developers, for game developers.

While building our own AI RPG, we ran into the high costs, latency, and complexity of cloud-based AI tools. The result was GladeCore: a lightweight, on-device system designed from the ground up to meet the real production needs of studios.

For the next generation of AI-enabled games, scalability and unit economics matter. With zero per-interaction costs, GladeCore makes it possible to have dozens, or even hundreds of intelligent NPCs constantly interacting with players without breaking your budget.

GladeCore NPCs aren’t just chatbots. They:

• Express emotions
• Develop unique personalities and behaviors
• Remember conversations and context
• Generate creative, human-like responses

All fully controlled by the data and instructions you provide. GladeCore brings AI characters into your worlds in a way that’s performant, affordable, and truly game-ready.
