Generate Text With Vercel's AI SDK

Let's look at literally the simplest setup that the AI SDK supports: generating text.

Scrollycoding

You take the generateText function that you import from ai, pass it a prompt and a model, and you get back an object that contains some text.

The model we're using is Anthropic's claude-3.5-haiku, which we're getting from Vercel's @ai-sdk/anthropic.

If we wanted to, we could specify a different model - let's say we're using claude-3.5-sonnet instead.

We can then use the function that we've created called answerMyQuestion.

Let's say we ask it "what is the chemical formula for dihydrogen monoxide?"

When we run this, it will call Anthropic with our query and get back the answer to the question we asked it.

import { generateText } from "ai";

export const answerMyQuestion = async (
  prompt: string,
) => {
  const { text } = await generateText({
    model,
    prompt,
  });

  return text;
};

There's also a bunch of other stuff in this object that we get back, but we'll cover that in our other examples.

// Lots of other properties on
// this returned object!
const { text } = await generateText({
  model,
  prompt,
});

return text;
