# PreferredMinThroughput

Preferred minimum throughput (in tokens per second). Can be a number (applies to p50) or an object with percentile-specific cutoffs. Endpoints below the threshold(s) may still be used, but are deprioritized in routing. When using fallback models, this may cause a fallback model to be used instead of the primary model if it meets the threshold.

## Supported Types

### `float`

```python theme={null}
value: float = /* values here */
```

### `components.PercentileThroughputCutoffs`

```python theme={null}
value: components.PercentileThroughputCutoffs = /* values here */
```
