Questions About Xiaomi-Robotics-1-RoboCasa

How much GPU memory does Xiaomi-Robotics-1-RoboCasa need?

About 12.1 GB at 16-bit and 3 GB at 4-bit: the weights (5.1B parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run Xiaomi-Robotics-1-RoboCasa on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use Xiaomi-Robotics-1-RoboCasa commercially?

Yes. Xiaomi-Robotics-1-RoboCasa is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution.

MolmoAct2-Pretrain

Ai2

MolmoAct2-Pretrain adapts the Molmo2-ER vision-language backbone into a discrete autoregressive robot policy while keeping the Molmo2 token interface. Robot state is represented with discrete state tokens, and future one-second actions are represented with OpenFAST action tokens. This checkpoint is the pre-trained VLA backbone before the continuous flow-matching action expert is attached. It is intended for further post-training or fine-tuning, not direct continuous-control inference. Use this checkpoint for further MolmoAct2 training stages. It was converted with addactionexpert=false, so predictaction(...) is intentionally unavailable. Standard Transformers generation can still be used…
