昆仑万维再次开源奖励模型Skywork-Reward-V2
2025年7月4日，昆仑万维乘势而上，继续开源第二代奖励模型Skywork-Reward-V2系列。此系列共包含8个基于不同基座模型、参数规模从6亿到80亿不等的奖励模型，一经推出便在七大主流奖励模型评测榜单中全面夺魁，成为开源奖励模型领域的焦点。
奖励模型在从人类反馈中强化学习（RLHF）过程中起着关键作用。为打造新一代奖励模型，昆仑万维构建了包含4000万对偏好对比的混合数据集Skywork-SynPref-40M。在数据处理上，团队采用人机协同的两阶段流程，将人工标注的高质量与模型的规模化处理能力相结合。第一阶段，先构建未经验证的初始偏好池，借助
