<Accordion title="How to stream response while using OpenAI model in Embedchain?">
You can achieve this by setting `stream` to `true` in the config file.

<CodeGroup>
```yaml openai.yaml
llm:
  provider: openai
  config:
    model: 'gpt-3.5-turbo'
    temperature: 0.5
    max_tokens: 1000
    top_p: 1
    stream: true
```

```python main.py
import os
from embedchain import App

os.environ['OPENAI_API_KEY'] = 'sk-xxx'

app = App.from_config(config_path="openai.yaml")

app.add("https://www.forbes.com/profile/elon-musk")

response = app.query("What is the net worth of Elon Musk?")
# response will be streamed in stdout as it is generated.
```
</CodeGroup>
</Accordion>

<Accordion title="How to persist data across multiple app sessions?">
  Set up the app by adding an `id` in the config file. This keeps the data for future use. You can include this `id` in the yaml config or input it directly in `config` dict.
  ```python app1.py
  import os
  from embedchain import App

  os.environ['OPENAI_API_KEY'] = 'sk-xxx'

  app1 = App.from_config(config={
    "app": {
      "config": {
        "id": "your-app-id",
      }
    }
  })

  app1.add("https://www.forbes.com/profile/elon-musk")

  response = app1.query("What is the net worth of Elon Musk?")
  ```
  ```python app2.py
  import os
  from embedchain import App

  os.environ['OPENAI_API_KEY'] = 'sk-xxx'

  app2 = App.from_config(config={
    "app": {
      "config": {
        # this will persist and load data from app1 session
        "id": "your-app-id",
      }
    }
  })

  response = app2.query("What is the net worth of Elon Musk?")
  ```
