Struct OpenAIResponsesArguments 

pub struct OpenAIResponsesArguments {
    pub model: String,
    pub input: Vec<ResponsesMessage>,
    pub tools: Option<Vec<OpenAITool>>,
    pub temperature: Option<f32>,
    pub max_output_tokens: Option<u32>,
}

Request arguments for OpenAI’s Responses API endpoint (/v1/responses).

This API provides agentic tool calling where the model autonomously uses web_search, file_search, or code_interpreter tools. Unlike the Chat Completions API, the Responses API uses input instead of messages and tools instead of function definitions.

Example

use openai_rust2::chat::{OpenAIResponsesArguments, OpenAITool};

let args = OpenAIResponsesArguments::new(
    "gpt-5",
    vec![{
        "role": "user",
        "content": "What's the latest news about AI?"
    }],
).with_tools(vec![OpenAITool::web_search()]);

Fields

model: String

input: Vec<ResponsesMessage>

tools: Option<Vec<OpenAITool>>

temperature: Option<f32>

max_output_tokens: Option<u32>

Implementations

impl OpenAIResponsesArguments

pub fn new(model: impl AsRef<str>, input: Vec<ResponsesMessage>) -> Self

Create new OpenAIResponsesArguments for the OpenAI Responses API.

pub fn with_tools(self, tools: Vec<OpenAITool>) -> Self

pub fn with_temperature(self, temperature: f32) -> Self

Set the temperature for response generation (0.0 to 2.0).

pub fn with_max_output_tokens(self, max_tokens: u32) -> Self

Set the maximum output tokens.
