Model & Weights

Xiaomi-Robotics-U0, Xiaomi-Robotics-U0-4B, and Xiaomi-Robotics-U0-FlashAR support Scene Gen, Transfer, T2I, and X2I. The Sequence checkpoints support interleave_subtask and interleave_video with the eager backend.

Inference

The complete inference implementation, environment setup, configuration reference, command-line examples, and distributed inference instructions are available in inference/README.md.

The repository supports both eager execution and vLLM backends for AR and FlashAR inference. A Gradio demo is also provided for interactive T2I, X2I, Scene Gen, and Transfer workflows.

Training

Training code and environment configuration are reserved for training/README.md and will be added in a future release.
