SYNTHETIC-2

# 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
