| Metric              | Focus                                                                             |
| ------------------- | --------------------------------------------------------------------------------- |
| `success_rate`      | Share of episodes or tasks that complete successfully.                            |
| `pick_success_rate` | Share of episodes or tasks that complete successfully.                            |
| `task_success`      | Share of episodes or tasks that complete successfully.                            |
| `reward`            | Task reward from MoLMoSpaces language-guided navigation and interaction episodes. |

## Environment setup [#environment-setup]

### Runtime environment [#runtime-environment]

* **Conda env:** `molmospaces-runtime`.
* **Separate setup:** this benchmark expects a dedicated conda env rather than the unified runtime.
* Stage only the selected MolmoSpaces-Bench subset; the full public asset corpus is very large.

### Evaluation data [#evaluation-data]

* Candidate model outputs: set `WORLDFOUNDRY_MOLMOSPACES_RESULTS_PATH` to the generated-video or rollout artifact root.
* `${WORLDFOUNDRY_DATA_DIR}/datasets/molmospaces`
* `${WORLDFOUNDRY_CACHE_DIR}/repos/allenai--MolmoBot`

### Checkpoints & assets [#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 [#key-environment-variables]

* `WORLDFOUNDRY_MOLMOSPACES_ROOT`
* `WORLDFOUNDRY_MOLMOSPACES_RESULTS_PATH`

## Run Evaluation [#run-evaluation]

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

### Set Candidate Artifacts [#set-candidate-artifacts]

```bash
export WORLDFOUNDRY_GENERATED_ARTIFACT_DIR=/path/to/generated/artifacts
```

### Import Official Results [#import-official-results]

```bash
worldfoundry-eval zoo benchmark-run \
  --benchmark-id molmospaces \
  --mode normalizer \
  --official-results-path /path/to/official/results-or-report \
  --generated-artifact-dir "${WORLDFOUNDRY_GENERATED_ARTIFACT_DIR}" \
  --output-dir tmp/molmospaces/normalizer \
  --json
```

### Score Generated Artifacts [#score-generated-artifacts]

```bash
worldfoundry-eval zoo benchmark-run \
  --benchmark-id molmospaces \
  --mode official-run \
  --generated-artifact-dir "${WORLDFOUNDRY_GENERATED_ARTIFACT_DIR}" \
  --output-dir tmp/molmospaces/official-run \
  --json
```

### Direct In-Tree Runner [#direct-in-tree-runner]

```bash
worldfoundry-eval zoo benchmark-run --benchmark-id molmospaces --mode official-validation --official-results-path <official_results.json> --output-dir <out> --json
```

## Requirements [#requirements]

### Environment [#environment]

* `WORLDFOUNDRY_MOLMOSPACES_RESULTS_PATH`

### Outputs [#outputs]
