Metrics

VLABench external benchmark manifest for language-conditioned manipulation policy rollouts.

Task YAML

worldfoundry/data/benchmarks/tasks/external/vlabench.yaml

Primary

success_rate

Metric	Focus
`success_rate`	Share of episodes or tasks that complete successfully.
`task_success`	Share of episodes or tasks that complete successfully.
`episode_success`	Share of episodes or tasks that complete successfully.
`reward`	Cumulative reward on VLABench language-conditioned tabletop manipulation rollouts.

Environment setup

Runtime environment

Conda env: vlabench-runtime.
Separate setup: this benchmark expects a dedicated conda env rather than the unified runtime.
WorldFoundry provides contract and official result normalization for caller-provided VLABench outputs.

Evaluation data

Candidate model outputs: set WORLDFOUNDRY_VLABENCH_RESULTS_PATH to the generated-video or rollout artifact root.
${WORLDFOUNDRY_DATA_DIR}/datasets/vlabench
${WORLDFOUNDRY_CACHE_DIR}/repos/OpenMOSS--VLABench

Checkpoints & assets

This benchmark is primarily rollout- or official-result-driven; see catalog requires and the task YAML for policy/simulator checkpoints.

Key environment variables

WORLDFOUNDRY_VLABENCH_ROOT
WORLDFOUNDRY_VLABENCH_RESULTS_PATH

Run Evaluation

After preparing the assets and candidate artifacts listed on this page, use the public run entry points below.

Set Candidate Artifacts
