# Model Hyperparameters

{/* feishu-style:text-align:left */}
`temperature` represents the sampling temperature. Higher values (such as 0.8) will make the output more random, while lower values (such as 0.2) will make the output more deterministic.

{/* feishu-style:text-align:left */}
`top_p` represents the probability threshold for nucleus sampling, used to control the diversity of text generated by the model. The higher the value, the greater the diversity of the generated text.

In thinking mode, the `mimo-v2.6-flash`, `mimo-v2.6-pro`, `mimo-v2.6-pro-ultraspeed` models do not support customizing the `temperature` and `top_p` parameters. Even if these parameters are passed in, the actual effective values will be forcibly set by the model to its recommended default values of `1.0` and `0.95`.

The default values and parameter ranges of `temperature` and `top_p` for different models are as follows:
