# IFBench

An exact mirror of the single-turn test data from [AllenAI IFBench](https://github.com/allenai/IFBench).
Credit: Valentina Pyatkin, Saumya Malik, Victoria Graf, Hamish Ivison, Shengyi Huang, Pradeep Dasigi,
Nathan Lambert, and Hannaneh Hajishirzi, [Generalizing Verifiable Instruction Following](https://huggingface.co/papers/2507.02833).

## Provenance and license

- Source revision: `{args.source_revision}`.
- Source file: [`ifbench/data/IFBench_test.jsonl`]({source}).
- Original file SHA-256: `{hashlib.sha256(raw).hexdigest()}`.
- No filtering, prompt changes, or row reordering. All original fields and values are preserved.
- `kwargs` uses the Hugging Face Datasets JSON feature to preserve heterogeneous argument dictionaries;
  use `datasets>=4.7.0` to load it as a list of dictionaries. Other fields are `key`, `prompt`, and `instruction_id_list`.
- The data is licensed under [ODC-BY-1.0](https://opendatacommons.org/licenses/by/1-0/), as stated in the
  [upstream README](https://github.com/allenai/IFBench/blob/{args.source_revision}/README.md#licensing).
  It is intended for research and educational use under Ai2's Responsible Use Guidelines.
  It includes outputs generated by third-party models, which may be subject to separate terms.
- Verifier code is separately Apache-2.0 licensed; it is not part of this dataset release.

## Reproducing

The builder is published at `scripts/create_dataset.py`. Exact publication invocation:

```bash
python scripts/create_dataset.py --output-dataset {args.output_dataset} --source-revision {args.source_revision}
```

To reproduce independently, use an unused repository name under your own namespace. The builder refuses to overwrite
an existing repository. It requires `datasets>=4.7.0` and `huggingface_hub`, and a token with write access to the destination.

## Loading

```python
from datasets import load_dataset

dataset = load_dataset("{args.output_dataset}", "default", split="test")
```

Pin a Hub commit revision for reproducible evaluation. This repository contains evaluation data, not training data.
