Ningyuan Jiang is a Senior AI Gameplay Designer at miHoYo. He spent his first years at the studio as a Level Designer on Genshin Impact, building open-world gameplay and world quests. In 2024 he moved into AI and gameplay research, and has since owned the full-lifecycle implementation of Nalo, the AI character at the center of Petit Planet. His design work sits at the boundary between classical AI architectures, GOAP and HTN, and modern LLM capabilities, with a focus on producing social behaviors that are both emergent and controllable.
