> **Info**
>
> Flux's end-of-turn detection is configurable to match your use case. Use `eot_threshold` for standard turn detection, or enable `eager_eot_threshold` for ultra-low latency response generation. See the [End-of-Turn Configuration](/docs/flux/configuration) for detailed configuration guidance.
