Stream Text to Terminal Solution

All right, here's what the solution looks like.

import { google } from "@ai-sdk/google"
import { streamText } from "ai"

const model = google("gemini-2.0-flash")

const stream = streamText({
  model,
  prompt: "Give me the first paragraph of a story about an imaginary planet.",
})

for await (const chunk of stream.textStream) {
  process.stdout.write(chunk)
}

We have our model, gemini-2.0-flash, and we have our prompt being passed to streamText. When I run this, we will see the new chunk.

If I try that again, you'll notice the chunks just popping in piece by piece instead of having to wait for the entire thing.

streamText is going to be one of the core primitives that we use going forward as we hook things up to the UI and it's much more useful than generateText in providing a better user experience.

Nice work and I will see you in the next one.
