# Pi-Bench Tasks
**Code and full benchmark:** [GitHub repository](https://github.com/Simplified-Reasoning/Pi-Bench)
**Paper:** [arXiv:2605.14678](https://arxiv.org/abs/2605.14678)
**Project page:** [simplified-reasoning.github.io/Pi-Bench](https://simplified-reasoning.github.io/Pi-Bench/)
This lightweight dataset exposes only the `task.yaml` files from Pi-Bench so
people can quickly inspect the benchmark tasks in the Hugging Face Dataset
Viewer.
Pi-Bench evaluates proactive personal assistant agents in long-horizon
workflows. It contains 100 multi-turn tasks across 5 domain-specific personas:
`researcher`, `marketer`, `pharmacist`, `law_trainee`, and `financier`.
Each row corresponds to one `data/<role>/tasks/<task_id>/task.yaml` file. The
`yaml` column preserves the original YAML text, while the other columns extract
common fields for filtering and browsing.
