ActiveArena-VLA weights

This directory contains the three 100,000-step checkpoints used by the ActiveArena policy configurations. Use these files with the ActiveArena-VLA code project and the ActiveArena evaluation environment. See the project website for a visual overview.

Configuration	Framework	History	State	VLM text supervision
oft_instruction_action_12_ws	QwenOFTState	12 action keyframes	Yes	Task instruction
oft_subtask_action_12_wos	QwenOFT	12 action keyframes	No	Subtask instruction
oft_subtask_action_12_ws	QwenOFTState	12 action keyframes	Yes	Subtask instruction

Each configuration directory contains:

<configuration>/
├── checkpoints/
│   └── steps_100000_pytorch_model.pt
├── config.yaml
├── config.full.yaml
└── dataset_statistics.json

The configuration files and normalization statistics are frozen release metadata. Keep them alongside checkpoints/: they are part of the checkpoint bundle. Each weight file is approximately 4.97 GB; the three bundles total approximately 14.90 GB (decimal units).

Run a policy server

Install the ActiveArena-VLA dependencies and prepare the Qwen3-VL-2B-Instruct base model assets at playground/Pretrained_models/ActiveArena/Qwen3-VL-2B-Instruct within the code project, as referenced by the supplied configs. Base model assets, datasets, and the simulation environment are not included in this bundle.

From the ActiveArena-VLA code directory:

MODEL=oft_subtask_action_12_ws
export ACTIVEARENA_VLA_ROOT="$PWD"
export ACTIVEARENA_VLA_PYTHON="$(command -v python)"
export POLICY_CKPT_PATH="/path/to/ActiveArena-VLA-weights/$MODEL/checkpoints/steps_100000_pytorch_model.pt"
bash "examples/ActiveArena_Astribot/train_files/managed_runs/$MODEL/run_policy_server.sh"

Set MODEL to any configuration listed above. Follow the ActiveArena project instructions to connect the evaluation client to the policy server.

File integrity and upload

manifest.json lists the size and SHA-256 digest of all 12 model bundle files. The copies were verified against hashes calculated while reading the source files. After downloading, verify from this directory:

./verify.sh

.gitattributes configures Git LFS for the .pt weights when uploading through Git. The same bundle is published at leeibo/ActiveArena-VLA. Keep the manifest and SHA-256 file beside the weights when mirroring it; do not commit the raw .pt files to a regular Git object store.
