1,500 单词 ~= 2048 tokens 在OpenAI 的API 参数中,max _ tokens 参数指定模型应该生成一个最大长度为60个令牌的响应。可以通过https://platform.openai.com/tokenizer 来观察token 的相关信息。 2. token 的特点 我们可以先用OpenAI 的playground 来看一个例子“Dec 31,1993. Things are getting crazy.” 使...

max_tokens:该参数用于设置模型可以生成的令牌的最大数量。此参数控制文本生成的长度。默认值是128个token。 temperature:温度,介于0和1之间。较高的值(如0.8)将使输出更加随机,而较低的值(如0.2)将使输出更加集中和确定。缺省值为1。 top_p:温度采样的替代方案,...
