# Basic Agent

> Run a GPT model through the CometAPI gateway in sync, async, and streaming modes.

## Code

```python basic.py theme={null}
import asyncio

from agno.agent import Agent, RunOutput  # noqa
from agno.models.cometapi import CometAPI

agent = Agent(model=CometAPI(id="gpt-5.2"), markdown=True)

# Get the response in a variable
# run: RunOutput = agent.run("Explain quantum computing in simple terms")
# print(run.content)

if __name__ == "__main__":
    # --- Sync ---
    agent.print_response("Explain quantum computing in simple terms")

    # --- Sync + Streaming ---
    agent.print_response("Explain quantum computing in simple terms", stream=True)

    # --- Async ---
    asyncio.run(agent.aprint_response("Share a 2 sentence horror story"))

    # --- Async + Streaming ---
    asyncio.run(
        agent.aprint_response(
