​
repetition_penalty
number<float>
default:1.5

The repetition penalty. We do not recommend changing this from the default value. Typical range is 1 to 2. Float that penalizes new tokens based on whether they appear in the prompt and the generated text so far. Values > 1 encourage the model to use new tokens, while values < 1 encourage the model to repeat tokens.

​
temperature
number<float>
default:0.5

The temperature. We do not recommend changing this from the default value. Typical range is 0 to 1. Float that controls the randomness of the sampling. Lower values make the model more deterministic, while higher values make the model more random. Zero means greedy sampling.

​
top_p
number<float>
default:1

The top p. We do not recommend changing this from the default value. Typical range is 0 to 1. Float that controls the cumulative probability of the top tokens to consider. Must be in (0, 1]. Set to 1 to consider all tokens.
