TypeScript error using OpenAI Responses API — ResponseInputImage.detail required even though documentation doesn't show it

I'm trying to use the OpenAI Responses API with image input (Vision). Following the official documentation example. I am getting this type error

Type '{ type: "input_text"; text: string; } | { type: "input_image"; image_url: string; }' is not assignable to type 'ResponseInputContent'.

This is the example from openAI documentation page that is returning the error.

import OpenAI from "openai";
const client = new OpenAI();

const response = await client.responses.create({
    model: "gpt-5",
    input: [
        {
            role: "user",
            content: [
                {
                    type: "input_text",
                    text: "What is in this image?",
                },
                {
                    type: "input_image",
                    image_url: "https://openai-documentation.vercel.app/images/cat_and_otter.png",
                },
            ],
        },
    ],
});

console.log(response.output_text);

The reason you are encountering this error is that when you have an input type of input_imageYou also need to specify detail as it is a required type of ResponseInputImage

const response = await client.responses.create({
  model: "gpt-5",
  input: [
    {
      role: "user",
      content: [
        {
          type: "input_text",
          text: "Analyze the following ingredients list",
        },
        {
          type: "input_image",
          image_url:
            "https://openai-documentation.vercel.app/images/cat_and_otter.png",
          detail: "auto",
        },
      ],
    },
  ],
});

console.log(response.output_text);
