API Parameters

Name	Type	Default	Description
`frequency_penalty`	number	0	Penalize tokens by their frequency so far. Positive values reduce repetition.
`logit_bias`	object	—	Map of token-id to bias (-100…100) added to the logit before sampling.
`max_tokens` deprecated	integer	—	Deprecated. Use max_completion_tokens.
`min_p`	unknown	—	—
`presence_penalty`	number	0	Penalize tokens that have appeared at all so far. Positive values encourage new topics.
`repetition_penalty`	number	1	Penalize repeated tokens (>1.0 reduces repetition, <1.0 encourages it).
`response_format`	one of	—	Constrain output to a JSON schema or an enum (structured outputs).
`seed`	integer	—	Deterministic seed for sampling. Same seed + same prompt produces identical output.
`stop`	array	—	Up to 4 sequences where the API will stop generating tokens.
`structured_outputs`	boolean	—	Enable JSON-schema-constrained output.
`temperature`	number	1	Sampling temperature; higher values produce more random output. 0 is deterministic.
`top_k`	integer	—	Limit sampling to the top-k most likely tokens at each step.
`top_p`	number	1	Nucleus sampling: consider only tokens whose cumulative probability ≥ top_p.

Standard OpenAI-compatible parameters. Consult the provider docs for model-specific behaviour.
