Qwen-GR00T-Bridge-RT-1

StarVLA legacy QwenFM checkpoint for Bridge + RT-1 (30K)

This repository is named Qwen-GR00T-Bridge-RT-1, but its published config.yaml selects framework_py: QwenFM and a local VLM path named nora. The card preserves that discrepancy instead of relabeling the checkpoint as a verified current QwenGR00T artifact.

Model details

Because the VLM is identified only by a local directory name, no Hugging Face base_model is asserted in the metadata. Reconstruct the checkpoint using the packaged YAML and the compatible StarVLA revision; do not substitute a current backbone solely from this repository's display name.

Training details

SimplerEnv WidowX evaluation

The repository publishes four completed run logs for each WidowX task. The values below are recomputed from their terminal Average success fields.

This value is tied to the uploaded logs. The current Model Zoo has historical PI/GR00T naming and link inconsistencies for the Qwen2.5 Bridge + RT-1 rows, so its 63.6 entry is not attached to this artifact here.

Loading and evaluation

huggingface-cli download StarVLA/Qwen-GR00T-Bridge-RT-1 \
  --local-dir Qwen-GR00T-Bridge-RT-1

export CKPT=$PWD/Qwen-GR00T-Bridge-RT-1/checkpoints/steps_30000_pytorch_model.pt
python deployment/model_server/server_policy.py \
  --ckpt_path "$CKPT" \
  --port 10093 \
  --use_bf16

For WidowX evaluation use the SimplerEnv client and normalization key oxe_bridge. oxe_rt1 is the second training-mixture key.

Intended use and limitations

This is a legacy research artifact with an unresolved public identity mismatch between the Hub name, configured framework, and local VLM path. Its bundled SimplerEnv logs are usable as evidence for the 30K checkpoint, but the artifact should not be advertised as a drop-in current QwenGR00T model until the framework/backbone provenance is confirmed. It is not safety-tuned.
