# Deepgram Self-Hosted release 261001 requires a Flux TTS watermarker and drops Whisper

Markdown version of <https://harbyn.com/changes/deepgram/2026-10-01-deepgram-self-hosted-release-261001-adds-watermarking-to-flux-tts-audio-removes>.

Breaking change - Deepgram. medium severity. In effect.

Self-Hosted release 261001 watermarks Flux TTS audio: deployments with Flux TTS must add the watermarker model file and set watermarker\_uuid under flux\_tts, or Engine will not start; Helm upgrades fail until fluxTts.watermarkerUuid is set. Engine no longer supports Whisper models, so Whisper deployments must migrate to Nova-3 before upgrading. Applies to self-hosted deployments only.
