HY-Embodied-0.5
Tencent ships open-weights embodied foundation models in two sizes (2B MoT and 32B MoE) — tuned for spatial-temporal perception and robot VLA control, beating same-size peers on 16 of 22 benchmarks.

What is it?
HY-Embodied-0.5 is a family of open-weights foundation models from Tencent Robotics X and the Hunyuan vision team, aimed specifically at physical agents. It ships in two sizes: a 2B Mixture-of-Transformers model with 2.2B activated parameters for edge deployment, and a larger 32B MoE model for heavier reasoning. The weights, paper and inference code for the 2B variant were open-sourced on April 9.
How does it work?
The architecture is a Mixture-of-Transformers that uses latent tokens to route computation per modality (vision, language, action) instead of a single dense stack. The 2B model is distilled on-policy from the 32B teacher. Training uses over 100 million embodied and spatial data points and more than 200 billion tokens, with special attention to spatial-temporal perception. The models are designed to plug into Vision-Language-Action pipelines as the perception and reasoning 'brain' that drives a downstream robot controller.
Why does it matter?
Most general-purpose VLMs stumble on the exact things embodied agents need — depth, motion, object persistence, plan consistency. HY-Embodied-0.5 is the first Tencent-backed open release purpose-built for that gap, and it beats similarly-sized models on 16 of 22 embodied benchmarks while the 32B variant tracks frontier models like Gemini 3.0 Pro. For robotics teams that cannot ship a closed frontier API on a real robot, this is a usable foundation.
