## Overview

[`ArcherCodeR-Dataset`](https://huggingface.co/datasets/wizardII/ArcherCodeR-Dataset) is **a dataset of verifiable, challenging, and diverse coding questions (6.7K)**. This dataset is used to train the **`ArcherCodeR`** model series, which consists of code reasoning models trained using large-scale rule-based reinforcement learning with carefully designed datasets and training recipes.

We select, clean, and curate coding problems from open-source datasets, including

- [agentica-org/DeepScaleR-Preview-Dataset](https://huggingface.co/datasets/agentica-org/DeepScaleR-Preview-Dataset)
- [deepmind/code_contests](https://huggingface.co/datasets/deepmind/code_contests)
- [open-r1/codeforces](https://huggingface.co/datasets/open-r1/codeforces)

### 🔍 Key Notes:

- Both code_contests (DeepMind) and codeforces (Open-r1) datasets include regenerated test cases to mitigate false positives.
- Significant prompt duplication exists across sources. When duplicates occur, code_contests or codeforces data takes priority.

For more details on data processing, please refer to our [Zhihu article](https://zhuanlan.zhihu.com/p/1918765619614057424).

## Technical Report

The technical report will be released soon.
