Generating TextGenerate Text with Image Prompt

Generate text with image prompt

Some language models that support vision capabilities accept images as part of the prompt. Here are some of the different formats you can use to include images as input.

URL

import { generateText } from 'ai';
import { openai } from '@ai-sdk/openai';

const result = await generateText({
  model: openai('gpt-4-turbo'),
  maxTokens: 512,
  messages: [
    {
      role: 'user',
      content: [
        {
          type: 'text',
          text: 'what are the red things in this image?',
        },
        {
          type: 'image',
          image: new URL(
            'https://upload.wikimedia.org/wikipedia/commons/thumb/3/3e/2024_Solar_Eclipse_Prominences.jpg/720px-2024_Solar_Eclipse_Prominences.jpg',
          ),
        },
      ],
    },
  ],
});

console.log(result);

File Buffer

import { generateText } from 'ai';
import { openai } from '@ai-sdk/openai';
import fs from 'fs';

const result = await generateText({
  model: openai('gpt-4-turbo'),
  maxTokens: 512,
  messages: [
    {
      role: 'user',
      content: [
        {
          type: 'text',
          text: 'what are the red things in this image?',
        },
        {
          type: 'image',
          image: fs.readFileSync('./node/attachments/eclipse.jpg'),
        },
      ],
    },
  ],
});

console.log(result);
