# VeriSoftBench

**VeriSoftBench** is a benchmark for evaluating neural theorem provers on software verification tasks in Lean 4.

The dataset contains 500 theorem-proving tasks drawn from 23 real-world Lean 4 repositories spanning compiler verification, type system formalization, applied verification (zero-knowledge proofs, smart contracts), semantic frameworks, and more.

## Dataset Contents

This Hugging Face release contains the dataset of the benchmark tasks only. For the full end-to-end evaluation pipeline, please refer to the Github repository:

👉 https://github.com/utopia-group/VeriSoftBench

Each task in `verisoftbench.jsonl` contains:

- Theorem name, statement, and source location
- Filtered dependencies (library defs, repo defs, local context, lemmas)
- Ground truth proof
- Metadata (category, difficulty metrics, Aristotle subset membership)
