 The `--n_predict` option controls the number of tokens the model generates in response to the input prompt. By adjusting this value, you can influence the length of the generated text. A higher value will result in longer text, while a lower value will produce shorter text. A value of -1 will cause text to be generated without limit.

-Temperature is a hyperparameter that controls the randomness of the generated text. It affects the probability distribution of the model's output tokens.
