About MotionGPT

MotionGPT is a unified motion-language model that treats human motion as a foreign language, enabling diverse motion-related tasks through a single framework. It uses discrete vector quantization to convert 3D motion into motion tokens, then performs language modeling on both motion and text. Pre-trained on a mixture of motion-language data and fine-tuned on prompt-based question-answer tasks, MotionGPT achieves state-of-the-art performance on text-driven motion generation, motion captioning, motion prediction, and motion in-between. Developed by researchers from Fudan University, Tencent PCG, and ShanghaiTech University, and published at NeurIPS 2023, it provides a versatile and user-friendly approach to multimodal motion understanding.
