promptExtend
boolean可选true

Whether to enable prompt intelligent rewriting. After activation, use the large model to intelligently rewrite the input prompt. For shorter prompt generation, the effect is significantly improved, but it will increase the time consumption.

seed
integer可选—

Randomly select seeds with a value range of [0, 2147483647]. If not specified, the system will automatically generate random seeds. If you need to improve the reproducibility of the generated results, it is recommended to fix the seed value. Please note that due to the probabilistic nature of model generation, even with the same seed, it cannot be guaranteed that the results generated each time will be completely consistent
