Xiaomi-Robotics-1-RoboCasa

This repository contains the Hugging Face checkpoint used by Xiaomi-Robotics-1 for RoboCasa evaluation. It includes the model weights, custom Transformers model and processor code, tokenizer files, and RoboCasa action normalization statistics.

Requirements

The reference environment uses:

Python 3.11
PyTorch 2.8.0
Transformers 4.57.1
FlashAttention 2

The custom model and processor must be loaded with trust_remote_code=True.

Loading

import torch
from transformers import AutoModel, AutoProcessor

model_id = "XiaomiRobotics/Xiaomi-Robotics-1-RoboCasa"

processor = AutoProcessor.from_pretrained(
    model_id,
    trust_remote_code=True,
    use_fast=False,
)
model = AutoModel.from_pretrained(
    model_id,
    trust_remote_code=True,
    attn_implementation="flash_attention_2",
    dtype=torch.bfloat16,
).cuda()

For reproducible multi-GPU evaluation, use the standard eight-server launcher in the companion source repository.

RoboCasa Evaluation

Use the companion Xiaomi-Robotics-1 source repository and follow eval_robocasa/README.md. The server launcher accepts either this Hugging Face repository ID after downloading it locally or a local snapshot path.
