# reasoningTokenCount

The number of output tokens that were part of the model’s reasoning output.

## Declaration

```swift
var reasoningTokenCount: Int
```

## Discussion

Discussion This value will always be less than or equal to totalTokenCount. A non-zero value requires the model to declare the reasoning capability.
