# Answer Streaming

Answer Streaming delivers generative responses incrementally, token by token in real time, instead of waiting for the full answer to be generated. This reduces perceived latency and creates a faster, more interactive experience — especially for longer answers.

Supported channel: Web/Mobile SDK only.

<Note>: When streaming is enabled, Search API responses are not returned. Streaming works only through compatible SDK-based and channel integrations where responses can be rendered progressively.</Note>

### Supported Models

| Model           | Default Prompts                                  | Custom Prompts  |
| --------------- | ------------------------------------------------ | --------------- |
| OpenAI          | ✅ Streaming-enabled prompts available by default | ✅ Supported     |
| Azure OpenAI    | ❌ No Default Prompts                             | ✅ Supported     |
| Other providers | ❌ Not supported                                  | ❌ Not supported |

### Enabling Streaming

Streaming is enabled through **prompt configuration**, not a global setting. The steps differ depending on whether you use a default or custom prompt.

#### Using Default Prompts (OpenAI only)

For OpenAI models, streaming-enabled prompts are available out of the box. Navigate to **Configuration > Answer Generation**, select the generative model, and choose a streaming-enabled prompt from the list. Selecting it automatically enables streaming — no additional steps needed.

***

#### Using Custom Prompts (OpenAI and Azure OpenAI)

Both of the following steps are required for streaming to take effect:

**Step 1 — Add streaming options to the prompt body:**

```json theme={null}
"stream": true,
"stream_options": {
  "include_usage": true
}
```

**Step 2 — Enable the Streaming toggle in the UI.**

> Both steps are required. Enabling only the toggle or only the prompt option will not activate streaming.
