Minimum array length: 1
​
max_tokens
integer

Maximum number of tokens for generated content, upper limit is 2048

​
temperature
number

Sampling temperature, controls output randomness

Note:

  • Lower values (e.g. 0.1): More deterministic, focused output
  • Higher values (e.g. 0.9): More random, creative output
  • Range: (0, 1], excluding 0
Required range: x <= 1
Example:

0.7

​
top_p
number

Nucleus Sampling parameter

Note:

  • Controls sampling from tokens with cumulative probability
  • e.g. 0.9 means selecting from tokens reaching 90% cumulative probability
  • Range: (0, 1], excluding 0

Recommendation: Do not adjust temperature and top_p simultaneously

Required range: x <= 1
Example:

0.9
