Frequency penalty
Frequency penalty is a setting that discourages an AI from repeating the same words, with a stronger effect the more often a word has already appeared.
In more detail
Each time a token is used, its chance of being picked again drops a little more. Raising the penalty reduces repetitive phrasing; setting it too high can make text strange as the model avoids normal words.
It is mainly offered through developer APIs, alongside presence penalty.
