## Summary

NVIDIA publishes ONNX inference exports of its unified Metatron G1 scene and recovery policy, used by the Metatron browser demo and G1 Racer. The demo model takes 39 inputs and outputs joint PD targets, gains and raw actions, while the six-robot Racer network runs all robots in one batch. The files run on ONNX Runtime Web with WebGPU or WebAssembly, and NVIDIA says they are not safety-certified or validated on real hardware.
