Supported parameters

frequency_penalty
Frequency penalty
Lowers the chance of a token in proportion to how often it already appeared.
max_tokens
Max tokens
Upper bound on generated tokens. Output stops at the limit.
temperature
Temperature
Sampling temperature. Lower is steadier, higher is more varied. Often 0 to 2.
top_p
Top-p
Sample only from tokens whose cumulative probability reaches top_p.
