Researchers affiliated with Alibaba and the Hong Kong University of Science and Technology introduced Rollout-Time Intervention (RTI). During training, RTI applies multi-agent corrections to failed attempts using task-specific rubrics, then filters intervention traces that shift too far from the model’s distribution and reweights the retained data.

On the out-of-distribution Claw-Eval-Hard20 test, the paper reports a Pass@1 rate of 62.92% for the model trained with RTI. The task families in this evaluation were not used in synthetic training, but the experiment remains limited to researcher-created tasks and API simulations; the paper also reports an in-distribution result tied to the same task families. The findings do not establish general-purpose agent performance.

## Data

### Research result

Claw-Eval-Hard20; task families excluded from training synthesis; Pass@1

Methodology: The value is limited to the benchmark experiment reported in the paper; it is not a field result or general performance guarantee.

| Measure | Percent | Scope |
|---|---|---|
| RTI model Pass@1 on Claw-Eval-Hard20 out-of-distribution tasks | 62.92 | Claw-Eval-Hard20; task families excluded from training synthesis; Pass@1 |
