Pass a list of images to useObject.

Hi.

I have been struggling with this a while and maybe somebody have some idea on how to solve it :)

as the title says, I want to analyze a batch of images and return the response.
This is my route.

`import { streamObject } from 'ai';
import { openai as openaiSDK } from '@ai-sdk/openai';
import { ItemSchema } from '@/app/types/schema';

export const maxDuration = 300; // 5 minutes

export async function POST(req: Request) {
try {
const { experimental_attachments }: { experimental_attachments: string[] } = await req.json();

if (!experimental_attachments) {
  return new Response(JSON.stringify({ error: 'No image provided' }), {
    status: 400,
    headers: { 'Content-Type': 'application/json' },
  });
}

const result = await streamObject({
  schema: ItemSchema,
  model: openaiSDK('gpt-4o'),
  maxTokens: 1000,
  maxRetries: 3,

  messages: [
    {
      role: 'system',
      content: `You are an AI assistant specialized in detecting and listing items from images. 
          Provide accurate information on all items visible in the image below.`,
    },
    {
      role: 'user',
      content: [
        {
          type: 'text',
          text: `Analyze the image and list all visible items,
            be very detailed. And if you see multiple items that are similar write them all down.
          `,
        },
        {
          type: 'image',
          image: experimental_attachments[0],
        },
      ],
    },
  ],
});
return result.toTextStreamResponse();
`
`

} catch (error) {
console.error('Error detecting inventory items:', error);
return new Response(
JSON.stringify({
error: 'Failed to detect inventory items',
detail: error instanceof Error ? error.message : String(error),
}),
{ status: 500, headers: { 'Content-Type': 'application/json' } },
);
}
}
`

if i have an index in the type
image: experimental_attachments[0], then this is working,
But i want to pass a list of images and analyze them and the response.
Has anyone a good solution or were i can read up on this?
