# Xiaomi open-sources Xiaomi-Robotics-1, a VLA trained on 100K+ hours of real trajectories

Xiaomi published Xiaomi-Robotics-1 on 2026-07-16, a 5B vision-language-action model pretrained on over 100K hours of real-world UMI manipulation trajectories and post-trained on 10K+ hours of cross-embodiment data; weights (Apache-2.0) followed on Hugging Face on 2026-07-28 with top open results on RoboCasa365 and VLABench.

## Key facts
- Data: 100K+ hours real-world UMI trajectories (pretraining) + 10K+ hours cross-embodiment robot data (post-training)
- RoboCasa 74.5%, RoboCasa365 57.4%, VLABench 59.1% (authors' comparison tables)
- Open weights: XiaomiRobotics/Xiaomi-Robotics-1-5B (Apache-2.0); code released 2026-08-03
- Paper reports strong scaling with data and model size

## What happened

Xiaomi's robotics team released one of the largest real-data-trained open VLAs, following Xiaomi-Robotics-0 (Feb 2026).

## Why it matters

It makes a 100K-hour-scale robot model openly available, narrowing the data gap between closed US labs and open Chinese releases.
