If a token has appeared in the previous text, the model will be penalized when generating this token.

A smaller presence_penalty indicates that the model considers fewer previously generated tokens, which may result in repeated content in the text.

A larger value of presence_penalty indicates that the model tends to generate new tokens that have not appeared before, and the generated text is more diversified.
