When we discuss Models, we are normally referring to Large Language Models (LLMs). These models act as the brain of your Agents - enabling them to reason, act, and respond to the user. The better the model, the smarter the Agent. 
from agno.agent import Agent
from agno.models.openai import OpenAIChat

agent = Agent(
    model=OpenAIChat(id="gpt-5-mini"),
    description="Share 15 minute healthy recipes.",
    markdown=True,
)
agent.print_response("Share a breakfast recipe.", stream=True)

​
Error handling

You can set exponential_backoff to True on the Agent to automatically retry requests that fail due to third-party model provider errors. 
agent = Agent(
    model=OpenAIChat(id="gpt-5-mini"),
    exponential_backoff=True,
    retries=2,
    retry_delay=1,
)

​
