▶ Start

What you'll have at the end

The same call switched to streaming mode, so words appear on screen as they arrive instead of all at once.

Before you start

You need

A backend script or endpoint that already calls a language-model API with one prompt and hands back the whole finished reply in a single response, plus a page that shows that reply once it lands.

Not covered

Remembering earlier turns of a conversation, retrying a dropped or rate-limited call, and streaming partial arguments for a tool call are separate pieces this recipe leaves alone.

Where to go next

Retry a rate-limited API call with backoff instead of a crash

Your streamed call still needs to survive a rate limit or a dropped connection once it's live.

Give a multi-turn chat real memory of earlier turns

You want the streamed reply to also remember earlier turns of the same conversation.
