## Code

```python tool_use.py theme={null}
import asyncio
import os

from agno.agent import Agent
from agno.models.portkey import Portkey
from agno.tools.websearch import WebSearchTools

agent = Agent(
    model=Portkey(
        id="@your-provider-slug/gpt-5-nano",
        portkey_api_key=os.getenv("PORTKEY_API_KEY"),
    ),
    tools=[WebSearchTools()],
    markdown=True,
)

if __name__ == "__main__":
    # --- Sync ---
    agent.print_response("What are the latest developments in AI gateways?")

    # --- Sync + Streaming ---
    agent.print_response(
        "What are the latest developments in AI gateways?", stream=True
    )

    # --- Async ---
    asyncio.run(
        agent.aprint_response("What are the latest developments in AI gateways?")
    )

    # --- Async + Streaming ---
    asyncio.run(
        agent.aprint_response(
            "What are the latest developments in AI gateways?", stream=True
        )
    )
```
