### This Release Contains The Following Changes

- Adds support for [Flux](https://flux.deepgram.com), our new turn-based streaming speech-to-text model! Flux is purpose-built for voice agent use-cases.
  - Because of its resource usage, **Flux must be run in its own self-hosted deployment** separate from any other Deepgram models, even other speech-to-text models like Nova-3.
  - Connect to Flux's new `/v2/listen` endpoint using `model=flux-general-en`, such as: `http://localhost:8080/v2/listen?model=flux-general-en`. Do not pass an additional `language` parameter.
  - Flux is currently English-only.
  - Contact your Deepgram account representative for access to the Flux model.
  - Get started with Flux's [developer docs](/guides/streaming-audio-flux-quickstart) and [API reference](/guides/self-hosted-deployments-2-reference-speech-to-text-listen-flux).
  - Learn more in Flux's [changelog entry](/guides/self-hosted-deployments-changelog#introducing-flux-conversational-speech-recognition-to-solve-the-biggest-problem-in-voice-agents--interruptions), [Announcement Blog](https://deepgram.com/learn/introducing-flux-conversational-speech-recognition), and try our [Interactive Demo](https://flux.deepgram.com).
  - To enable Flux in your self-hosted deployment, make the following additions to your TOML files:
    - api.toml:
      ```
      [features]
      listen_v2 = true
      ```
    - engine.toml:
      ```
      [flux]
      enabled = true
      ```

- Resolves a Nova-3 diarization issue present in the prior release (`release-250929`).

- **General Improvements** — Keeps our software up-to-date.
