Unverified温度值越高，模型输出概率分布越平滑，随机性越强；Top-p采样只从累积概率达到阈值的最小token集合中采样66% similarUnverifiedMin-K% 方法通过检查模型在文本中最低概率token的平均对数概率来判断样本是否为训练集成员63% similarUnverifiedTop-P设为0.5时，仅从概率前50%的词中进行选择；设为1时，所有词都有被选中的机会63% similarUnverifiedTop-p采样（核采样）由Holtzman等人2020年提出，按概率从高到低累加至阈值p后从最小词集中采样62% similarUnverified马尔可夫头仅需记录前一个token状态即可推导下一token修正概率，参数量通常不超过原模型的0.1%61% similar
