# 07 Streaming

Script: `example/07_streaming.py`.

Streaming sends normalized `RathLLMStreamDelta` objects to `on_event` while the loop still appends one durable assistant chunk after the model round completes.

```bash
python example/07_streaming.py
```

| Delta field | Meaning |
| --- | --- |
| `content_delta` | Incremental assistant text. |
| `finish_reason` | Terminal reason for the model round. |
| `usage` | Provider-reported token usage when available. |

OpenAI-compatible and Anthropic built-in clients both support streaming in v1.2.
