+
+    In the original [paper](https://arxiv.org/pdf/1909.05858.pdf), the authors suggest the use of a penalty of around
+    1.2 to achieve a good balance between truthful generation and lack of repetition. To penalize and reduce
+    repetition, use `penalty` values above 1.0, where a higher value penalizes more strongly. To reward and encourage
+    repetition, use `penalty` values between 0.0 and 1.0, where a lower value rewards more strongly.

+        penalty (`float`):
+            The parameter for repetition penalty. 1.0 means no penalty. Above 1.0 penalizes previously generated
