### What it is RynnBrain 1.1 is Alibaba DAMO Academy’s embodied foundation model family, spanning **2B, 9B, and 122B-A10B** scales. ### What changed from v1.0 - Built with a unified spatio-temporal and physically grounded training framework. - Covers embodied perception, spatial reasoning, localization, and planning. - Adds contact-point prediction across the family. - Adds native 3D grounding for the 2B and 9B models, making outputs more directly aligned with manipulation. - RynnBrain-VLA introduces a unified cross-embodiment action space plus embodiment-specific masking. ### Deployment and results - Deployed on **Unitree G1, Astribot-S1, and Tianji-Wuji**. - The 122B-A10B model reportedly beats all evaluated proprietary and open-source models on **VSI-Bench, MMSI, and RefSpatial-Bench**. - Real-robot experiments show RynnBrain-initialized policies outperform Qwen-based and representative generalist VLAs, and joint multi-task / multi-embodiment training improves success rates and process scores.
