OpenThoughts3-1.2M
1.2M reasoning traces — 850k math, 250k code, and 100k science questions — with chains of thought generated by QwQ-32B. The result of 1,000+ controlled experiments on reasoning-data curation, and the training set behind OpenThinker3-7B, the state-of-the-art open-data 7B reasoning model (53% AIME 2025). The reference open recipe for distilling reasoning ability.

常见问题
OpenThoughts3-1.2M 可以商用吗?
可以——OpenThoughts3-1.2M 采用 Apache 2.0 宽松许可证,允许商业使用,包括训练用于产品的模型。发布前请查看数据集卡片中的署名要求。
OpenThoughts3-1.2M 有多少数据?需要全部使用吗?
OpenThoughts3-1.2M 包含 1.2M Rows。通常不需要全部:风格和格式微调只需几百到几千条样本——先加载切片(如 split="train[:1000]"),质量到达瓶颈时再扩大规模。
OpenThoughts3-1.2M 最适合做什么?
Distilling strong math/code/science reasoning into 7B–32B models。它属于数据集中心的「推理」板块,那里有替代和互补的数据集。
