from agno.models.xai import xAI

agent = Agent(model=xAI(id="grok-3"), markdown=True)

# 获取响应到一个变量中
# run_response: Iterator[RunResponseEvent] = agent.run("写一个两句的恐怖故事", stream=True)
# for chunk in run_response:
#     print(chunk.content)

# 在终端中打印响应
asyncio.run(agent.aprint_response("写一个两句的恐怖故事", stream=True))
```
