API Request structure for sending prompt and function information

Fields

model: String

Specifies the model name

messages: VecDeque<Message>

Array of prompt messages

tools: Vec<ToolDef>

Defines the tools available to the model

tool_choice: Value

Instructions for function calls:

• “auto”: AI will make one or more function calls if needed
• “none”: No function calls will be made
• “required”: One or more function calls are mandatory
• {“type”: “function”, “function”: {“name”: “<function_name>”}}: Calls the function <function_name>

parallel_tool_calls: Option<bool>

Specifies whether to make parallel tool calls default: true

temperature: Option<f64>

Specifies the diversity of tokens generated by the model Range: 0.0..2.0 default: 0.8 (soft specification)

max_completion_tokens: Option<u64>

Specifies the maximum number of tokens generated by the model

top_p: Option<f64>

Specifies the width of the probability distribution for selecting the next token Lower values result in more predictable text

reasoning_effort: Option<String>

Specifies the level of effort for model reasoning:

• “low”: Low effort
• “medium”: Medium effort
• “high”: High effort default: “medium”

presence_penalty: Option<f64>

Specifies whether to apply a repetition penalty to the model Range: 2.0..-2.0

web_search_options: Option<WebSearchOptions>

Options for performing web search with available models
