GladeCore

Overview

GladeCore is a C/C++ SDK from Glade Studio for conversational NPCs that run locally. You drop a component on a character and get LLM-driven dialogue, speech-to-text and text-to-speech, all on the player's device, so there's no cloud round-trip and no per-interaction cost.

By default it ships a Llama 3.2 model of about 1B parameters fine-tuned for emotional, gameplay-style dialogue, and you can swap in other GGUF models or use cloud backends such as OpenAI, Anthropic or OpenRouter. Unreal and Godot run on the SDK on Windows and macOS; the Unity Asset Store version is a standalone plugin that doesn't get the Pro SDK features yet.

Key features

• On-device speech-to-text (Whisper) and local TTS (Piper, Kokoro), or ElevenLabs
• 10 tunable emotions plus character and world lore
• Lip sync and viseme output
• Pro: RAG with citations, agentic in-engine actions, tool calling and quest generation
• Pro: fine-tune custom models through the web platform
