# PublicServiceTier

The service tier this endpoint sells, or null for a standard endpoint. The same value whether the provider selects the tier with a request parameter or with a dedicated model id. Always the canonical tier: priority covers the fast request alias and the turbo, highspeed, and prime provider model-id spellings, none of which this field reports.

## Example Usage

```python theme={null}
from openrouter.components import PublicServiceTier

# Open enum: unrecognized values are captured as UnrecognizedStr
value: PublicServiceTier = "flex"
```

## Values

This is an open enum. Unrecognized values will not fail type checks.

* `"flex"`
* `"priority"`
* `"ultrafast"`
