DPO Mix 7K
A compact, curated DPO (Direct Preference Optimization) dataset of 7k chosen/rejected pairs, carefully selected from multiple high-quality sources. Ideal for running DPO experiments locally — small enough to fine-tune in under an hour on consumer GPUs while producing meaningfully aligned models.

{
"system": "You are a helpful assistant.",
"prompt": "Explain recursion in simple terms.",
"chosen": "Recursion is when a function calls itself to solve a smaller version of the same problem. Think of Russian nesting dolls — each doll contains a smaller version of itself until you reach the smallest one.",
"rejected": "Recursion refers to the process of defining a problem or function in terms of itself through self-referential expressions."

常见问题
DPO Mix 7K 可以商用吗?
可以——DPO Mix 7K 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。
DPO Mix 7K 有多少数据?需要全部使用吗?
DPO Mix 7K 包含 7k Pairs。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。
DPO Mix 7K 最适合做什么?
A small, balanced DPO starter set。它属于数据集中心的「偏好(RLHF / DPO)」板块,那里有替代和互补的数据集。
