# Tokens-per-minute rate limiting (/faq/tpm-issues)

If a provider rate-limits your agent, configure retries:

```python
from agno.agent import Agent
from agno.models.openai import OpenAIChat

agent = Agent(
    model=OpenAIChat(id="gpt-5.4-mini"),
    retries=3,
    delay_between_retries=2,
    exponential_backoff=True,
)
agent.print_response("Tell me about a breaking news story from New York.", stream=True)
```

`retries` defaults to `0`, so setting `exponential_backoff` or `delay_between_retries` alone has no effect. Set `retries` to the number of retry attempts you want.

| Parameter               | Default | Description                                |
| ----------------------- | ------- | ------------------------------------------ |
| `retries`               | `0`     | Number of retries after a failed run       |
| `delay_between_retries` | `1`     | Delay in seconds before each retry         |
| `exponential_backoff`   | `False` | Double the delay after each failed attempt |

OpenAI applies tier-based rate limits. See the [OpenAI rate limit docs](https://platform.openai.com/docs/guides/rate-limits) for the limits on your account.
