+<br>
+<br>
+👏这个模型可以用于问答、结合上下文做对话、做各种生成任务, 包括创意性写作, 也能回答一些像法律、新冠等领域问题. 它基于PromptCLUE-large结合数亿条功能对话多轮对话数据进一步训练得到.<br>
+<br>
+👀<a href='https://www.cluebenchmarks.com/clueai.html'>PromptCLUE-large</a>在1000亿token中文语料上预训练, 累计学习1.5万亿中文token, 并且在数百种任务上进行Prompt任务式训练. 针对理解类任务, 如分类、情感分析、抽取等, 可以自定义标签体系; 针对多种生成任务, 可以进行采样自由生成.  <br>
