Supported parameters
logprobsLogprobs
Return the log probability of each output token.
max_tokensMax tokens
Upper bound on generated tokens. Output stops at the limit.
response_formatResponse format
For example json_object or json_schema, to constrain the shape.
seedSeed
A fixed seed helps reproduce sampling. It does not guarantee byte-identical output.
temperatureTemperature
Sampling temperature. Lower is steadier, higher is more varied. Often 0 to 2.
top_logprobsTop logprobs
Also return the most likely alternatives at each position.
top_pTop-p
Sample only from tokens whose cumulative probability reaches top_p.
