+
+        A `templates` example of the dialogue generation task is:
+        ```json
+        {

+            "label": " {label}"
+        }
+        ```
+        An example `Template` of the field "input" here is "{history}\n{role}:".
+
+        and a dialogue generation `data` example is:
+        ```json
+        {
+            "history": [
+                {

+                "Jill Biden."
+            ],
+        }
+        ```
+        An example `RawData` of the field "role" here is "sys".
+
+        The resulting prompt (in the "input" field of the returned result) after conversion will be:
+
+            User: Who is the US president?
+            Assistant: Joe Biden.
+            User: Then who is his wife?

+        哺乳动物的远古“亲戚”，从而填补了进化链中从爬行动物到哺乳动物中缺少的一环。\n1987年，米切尔·洛林研究了一块盘龙类的头骨化石。
+        随着研究的深入，化石上的一些细节却使他困惑不解。因为大多数的盘龙类在腭部有很大的孔，而在较进化的兽孔类身上，这个孔已被封闭，四角龙
+        也有一个腭孔，但已明显缩小，其直径仅仅为0.635厘米。此外，盘龙类在头部背面有一块很大的骨，用以支持颌骨，在兽孔类中，这块骨头已大大
+        缩小了，而四角龙的这块骨要较兽孔类大，又较盘龙类稍小。更为重要的是，四角龙的头角上有个骨架，穿越颞孔的咀嚼肌像兽孔类那样直接依附
+        其上，而不像盘龙类那样由肌腱相接。\n这些发现使洛林相信，四角龙是盘龙类和兽孔类之间的一个过渡类型。他又把从12块盘龙类和兽孔类动物化石
+        中获得的信息输入电脑（包括腭孔、颞孔形状，头颅骨形状，牙齿数量和着生位置等），然后由电脑判断出两者之间的联系。结果表明，在进化树上，
+        通向兽孔类一边的第一个分叉就是四角龙。
+
