agents2agents/MolmoAct2-LIBERO-Jetson-Thor

MolmoAct2 LIBERO engines for Jetson AGX Thor

Prebuilt TensorRT engines for running allenai/MolmoAct2-LIBERO with vla-edge. This is the configuration used for our 2,000-episode LIBERO evaluation.

With the FP8 vision engine enabled, it scored 97.2% overall, matching the MolmoAct2 paper result within sampling noise. See the performance writeup for the methodology and per-suite results.

Download and verify

This repository is about 10.5 GB.

hf download agents2agents/MolmoAct2-LIBERO-Jetson-Thor \
  --local-dir vla-edge-libero
cd vla-edge-libero
python -c "from vla_edge.backends.tensorrt import artifacts; \
artifacts.check_compatible('.'); artifacts.verify_checksums('.'); \
print('bundle verified')"

Run

vla-edge-serve --embodiment libero --backend tensorrt \
  --engine-dir /path/to/vla-edge-libero/libero --fast-vision

The public API expects two images named image and wrist_image, plus the eight-value LIBERO state vector. The startup warmup executes every compiled stage.
