[QUESTION] How to use code_interpreter tool in Responses API?

[Krolmo]

How can we help?

I tried to add this through responseCreationOptions.Tools.Add(ResponseTool.Create...);
But there is only internal InternalCodeInterpreterTool in assembly.

How can I deal with it?

Hi @Krolmo. Thank you for reaching out and for your inquiry. The request for code_interpreter support is being tracked by #448, which points to an example of using it with the protocol overload in #487. For locality, I've copied that here:

var client = new OpenAIResponseClient("gpt-4.1", "<< YOUR API KEY >>");

// Form the OpenAI payload directly so that we can access the missing tool.  
var rawResponse = await client.CreateResponseAsync(
    BinaryContent.Create(BinaryData.FromObjectAsJson(new
    {
        model = "gpt-4.1",
        instructions = "You are a personal math tutor. When asked a math question, write and run code using the python tool to answer the question.",
        input = "I need to solve the equation 3x + 11 = 14. Can you help me?",
        tools = new[]
        {
            new
            {
                type ="code_interpreter",
                container = new { type = "auto"}
            }
        }
    })));

// The call returns a raw JSON response.  Translate to the associated model so that it is easier to work with.
var response = ModelReaderWriter.Read<OpenAIResponse>(rawResponse.GetRawResponse().Content);
Console.WriteLine($"The model answered:'{response.GetOutputText()}'");
