| [Configurable Parameters](/guides/streaming-audio-flux-configuration) | Tune `eot_threshold`, `eager_eot_threshold`, and `eot_timeout_ms` for optimal turn detection |

:::callout{intent="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](/guides/streaming-audio-flux-configuration) for detailed configuration guidance.
