Tencent Robotics X releases HY-Embodied-0.5: 2B + 32B open-source embodied AI foundation models, leads 16 of 22 benchmarks

Tencent Robotics X and HY Vision Team released HY-Embodied-0.5, a family of open-source foundation models built for real-world robotic agents (arXiv 2604.07430). The 2B model targets edge devices and leads state-of-the-art alternatives on 16 of 22 benchmarks; the 32B variant matches Gemini 3.0 Pro on embodied understanding tasks. Both use a Mixture-of-Transformers (MoT) architecture with modality-specific computing paths and latent tokens for fine-grained visual perception — critical for manipulation and navigation. A VLA (Vision-Language-Action) model trained on this foundation enables real-world robot control. Full code and model weights are public on April 7, 2026.
