**VirtualHuman** is a Unity plugin that interfaces with large language models and speech generation models to enable functionalities like AI assistants or AI companions. It utilizes TextMeshPro and Newtonsoft.Json in Unity, and outside Unity, it employs KoboldAI-KoboldCPP for local language model operation and VITS Simple API. Users configure various parameters including the VITSController, Large Language Model (LLM) type, LLM Controller, and translation process. It supports two LLM types: ChatGPT 3.5, which requires OpenAI’s APIKey, and KoboldAI-KoboldCPP for text generation. The plugin also uses Google Translate, necessitating a robust network environment. Future enhancements plan to incorporate Text-Generation-WebUI and ChatGPT 4.0.
