SSE se usa comúnmente para streaming de chat de IA, notificaciones en vivo, logs y observabilidad, y otros casos donde el servidor envía actualizaciones al cliente.

## Casos de uso { #use-cases }

Podrías usar esto para hacer stream de datos desde un servicio de **AI LLM**, desde **logs** o **telemetry**, o desde otros tipos de datos que puedan estructurarse en ítems **JSON**.

/// tip | Consejo

It looks like this:

```
data: {"name": "Portal Gun", "price": 999.99}

If you want to stream binary data, for example video or audio, check the advanced guide: [Stream Data](../advanced/stream-data.md).

But normally you won't have to worry about it, it's done automatically, continue reading. 🤓

///

## Use Cases { #use-cases }

You could use this to stream data from an **AI LLM** service, from **logs** or **telemetry**, or from other types of data that can be structured in **JSON** items.
