Chat Completion

Simple Chat

    let mut openai = OpenAI::new();
    let messages = vec![
        Message::new(String::from("user"), String::from("Hi there!"))
    ];
    openai
        .model_id(String::from("gpt-4o-mini"))
        .messages(messages)
        .temperature(1.0);
    let response: Response = openai.chat().unwrap();
    println!("{}", &response.choices[0].message.content);
    // Hello! How can I assist you today?

Chat with Json Schema

    struct Weather {
        location: String,
        date: String,
        weather: String,
        error: String,
    }
    let mut openai = OpenAI::new();
    let messages = vec![Message::new(
        String::from("user"),
        String::from("Hi there! How's the weather tomorrow in Tokyo? If you can't answer, report error."),
    )];
    // build json schema
    let mut json_schema = JsonSchema::new("weather".to_string());
    json_schema.add_property(
        String::from("location"),
        String::from("string"),
        Option::from(String::from("The location to check the weather for.")),
    );
    json_schema.add_property(
        String::from("date"),
        String::from("string"),
        Option::from(String::from("The date to check the weather for.")),
    );
    json_schema.add_property(
        String::from("weather"),
        String::from("string"),
        Option::from(String::from("The weather for the location and date.")),
    );
    json_schema.add_property(
        String::from("error"),
        String::from("string"),
        Option::from(String::from("Error message. If there is no error, leave this field empty.")),
    );
    // configure chat completion model
    openai
        .model_id(String::from("gpt-4o-mini"))
        .messages(messages)
        .temperature(1.0)
        .response_format(ResponseFormat::new(String::from("json_schema"), json_schema));

    // execute chat
    let response = openai.chat().unwrap();
    let answer: Weather = serde_json::from_str::<Weather>(&response.choices[0].message.content).unwrap();
    println!("{:?}", answer)
    // Weather {
    //     location: "Tokyo",
    //     date: "2023-10-01",
    //     weather: "Temperatures around 25°C with partly cloudy skies and a slight chance of rain.",
    //     error: "",
