## Introducing Flux: Conversational Speech Recognition to Solve the Biggest Problem in Voice Agents – Interruptions

#### Flux is here: the first real-time Conversational Speech Recognition model built for voice agents. Solve interruptions, cut latency, and ship natural conversations faster than ever.

Deepgram is proud to announce the release of [Flux](https://deepgram.com/learn/introducing-flux-conversational-speech-recognition), the first speech recognition model that knows when someone is actually done talking. Built for conversation, not transcription.

**Key Features:**

- **Model-integrated turn detection** that understands context and conversation flow, not just silence
- **Ultra-low latency when it matters most** - transcripts that are ready as soon as turns end
- **Nova-3 level transcription quality** - high-quality speech-to-text (STT) that’s every bit as accurate as the best models, including keyterm prompting
- **Radically simpler development** - one API replaces complex STT+VAD+endpointing pipelines, and conversation-native events designed to make voice agent development a breeze
- **Configurability for your use case** - the right amount of complexity, allowing developers to achieve the desired behavior for their agent

**Use Cases:**

Designed for real-time conversational applications: voice agents, AI assistants, IVR systems, and any application requiring natural dialogue flow. For pure transcription (meetings, captions, recordings), continue using Nova-3.

**Getting Started:**

Flux is **free throughout October 2025** for our OktoberFLUX promotion (up to 50 concurrent connections). Use `model=flux-general-en` via the new `/v2/listen` endpoint.
