VibeThinker SFT Stage 1 CoT

VibeThinker 第一阶段监督微调数据。仓库当前保持私有。

数据规模

train：1,842,263 条
validation：2,816 条
internal_test：2,813 条
总计：1,847,892 条

格式

主文件为 data/sft_stage1.jsonl，每行是一个独立 JSON 对象。训练内容采用 Qwen3.5 消息格式，包含 messages、稳定记录/问题标识、领域、切分、来源与验证证据。监督回答经过 CoT 格式检查，推理过程使用 <think>...</think> 边界。

数据处理

数据经过规范化、精确去重、近似去重、基准污染过滤、CoT 校验、稳定切分与领域质量门禁。SFT 域比例不是硬配额：通过质量门禁的数据不会因为代码数据不足而被额外裁剪。每个来源的许可与溯源信息保留在记录的 provenance 字段中；使用者应按原始数据源许可审查自己的使用场景。

训练使用

训练时读取 split == "train" 的记录；验证和内部测试切分不得混入训练。应使用仓库配套 pipeline 中冻结的 Qwen3.5 chat template，并在训练前复核文件摘要和记录数。
