Example

Generating Text

You can generate text using LangDB.ai models:

import { createLangDB } from '@langdb/vercel-provider';
import { generateText } from 'ai';

const langDB = createLangDB(
  apiKey: 'your_api_key',
  projectId: 'your_project_id',

);

const { text } = await generateText({
  model: langDB('openai/gpt-4o-mini'),
  prompt: 'Write a Python function that sorts a list:',
});

console.log(text);

Generating Images

You can also generate images using LangDB.ai's image models:

import { experimental_generateImage as generateImage } from 'ai';
import fs from 'fs';
import path from 'path';

const { images } = await generateImage({
  model: langDB.image('openai/dall-e-3'),
  prompt: 'A delighted resplendent quetzal mid-flight amidst raindrops',
});

const imagePath = path.join(__dirname, 'generated-image.png');
fs.writeFileSync(imagePath, images[0].uint8Array);
console.log(`Image saved to: ${imagePath}`);

import { embed } from 'ai';
