Idea
A bimodal motion-language AI model enabling developers and researchers to generate and understand human motion with natural language integration.
Research Paper
Core Innovation
This paper introduces MotionGPT3, a novel bimodal model that treats human motion as a second modality alongside language. It uniquely combines a motion Variational Autoencoder to encode continuous motion into latent space with a diffusion head to predict motion latents, enabling seamless cross-modal interaction. This approach overcomes prior challenges in continuous motion representation and preserves strong language understanding.

Research Paper Overview
MotionGPT3: Human Motion as a Second Modality
Summary
MotionGPT3 is a bimodal motion-language model that treats human motion as a second modality, addressing challenges in continuous motion representation and language intelligence degradation. It uses a motion Variational Autoencoder to encode raw motion into latent space and a diffusion head to predict motion latents, enabling effective cross-modal interaction and efficient multimodal training while preserving strong language capabilities.
