# InteractBench Dataset
Dataset artifacts for **InteractBench: Benchmarking LLMs on Competitive Programming under Unrevealed Information** (ICML 2026).
[Project page](https://www.interactbench.com) | [Paper (OpenReview)](https://openreview.net/forum?id=Y4T4w0Tj0l) | [Code](https://github.com/kmsgk0/InteractBench)
InteractBench is a benchmark of 322 interactive competitive-programming problems curated from Codeforces, AtCoder, IOI, and ICPC. Each problem ships with an executable local interactor, so evaluation runs fully offline without external judge submission.
Files:
- `problems.jsonl`: 298 standard interactive problems.
- `ioi.jsonl`: 24 IOI-style problems.
- `test_cases/*.tar.zst`: materialized problem test cases split into shards.
- `checksums.sha256`: SHA-256 checksums for released files.
Use:
```bash
sha256sum -c checksums.sha256
mkdir -p data/problems
for f in test_cases/*.tar.zst; do
tar --use-compress-program=unzstd -xf "$f" -C data/problems
done
python scripts/import_from_jsonl.py --type standard --input problems.jsonl --output-dir data/problems
python scripts/import_from_jsonl.py --type ioi --input ioi.jsonl --output-dir data/problems
```
