SYNTHETIC-2-RL

# SYNTHETIC-2

SYNTHETIC-2 is an open reasoning dataset spanning a variety of math, coding and general reasoning tasks along with reasoning traces generated in a collaborative manner. The dataset contains both high quality reasoning traces from Deepseek-R1-0528 ideally suited for SFT, as well as multiple reasoning traces from smaller models which can be used for difficulty estimation.

We release the following final dataset splits on Huggingface:

- [SYNTHETIC-2](https://huggingface.co/datasets/PrimeIntellect/SYNTHETIC-2): The full SYNTHETIC-2 dataset consisting of all prompts and completions along with rewards
- [SYNTHETIC-2-SFT-verified](https://huggingface.co/datasets/PrimeIntellect/SYNTHETIC-2-SFT-verified): The SFT split of SYNTHETIC-2 with responses from Deepseek-R1-0528 verified as correct (rewards of 1 for binary rewards and over 0.7 for non-binary rewards)
- [SYNTHETIC-2-SFT-unverified](https://huggingface.co/datasets/PrimeIntellect/SYNTHETIC-2-SFT-unverified): The SFT split of SYNTHETIC-2 with all responses, including those not verified as correct
- [SYNTHETIC-2-RL](https://huggingface.co/datasets/PrimeIntellect/SYNTHETIC-2-RL): The RL subset of SYNTHETIC-2 with difficulty annotations from Qwen3-32B, Qwen3-4B and DeepSeek-R1-0528-Qwen3-8B

# SYNTHETIC-2
SYNTHETIC-2是一款开放推理数据集，涵盖数学、编程及通用推理等多类任务，同时包含以协作方式生成的推理轨迹。该数据集既包含来自Deepseek-R1-0528的高质量推理轨迹，非常适合监督微调（Supervised Fine-Tuning，SFT），也收录了来自更小规模模型的多条推理轨迹，可用于任务难度评估。
