	// A list of messages comprising the conversation so far.
	Messages []*ChatMessage `json:"messages,omitempty"`

	// A list of functions the model may generate JSON inputs for.
	Functions []*ChatFunction `json:"functions,omitempty"`

	// Controls how the model responds to function calls. "none" means the model does not call a function, and responds to the end-user. "auto" means the model can pick between an end-user or calling a function. Specifying a particular function via {"name":\ "my_function"} forces the model to call that function. "none" is the default when no functions are present. "auto" is the default if functions are present.
	FunctionCall string `json:"function_call,omitempty"`

	// What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
	// We generally recommend altering this or top_p but not both.
	// Defaults to 1
	Temperature float64 `json:"temperature,omitempty"`

	// An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
	// We generally recommend altering this or temperature but not both.
	// Defaults to 1
	TopP float64 `json:"top_p,omitempty"`

	// How many chat completion choices to generate for each input message.
	// Defaults to 1
	N int `json:"n,omitempty"`

	// If set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a data: [DONE] message.
	// Defaults to false

	MaxTokens int `json:"max_tokens,omitempty"`

	// Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.
	// Defaults to 0
	PresencePenalty float64 `json:"presence_penalty,omitempty"`

	// Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.
	// Defaults to 0
	FrequencyPenalty float64 `json:"frequency_penalty,omitempty"`

	// Modify the likelihood of specified tokens appearing in the completion.
	// Accepts a json object that maps tokens (specified by their token ID in the tokenizer) to an associated bias value from -100 to 100. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.
	// Defaults to null
	LogitBias any `json:"logit_bias,omitempty"`
