Batch Diarization v2 model delivery for new self-hosted deployments

Section titled “Batch Diarization v2 model delivery for new self-hosted deployments”

Release 260514 ships Deepgram's new batch diarization model (v2) to self-hosted. New deployments provisioned through your Deepgram representative will receive only the v2 batch diarizer model on disk by default. To produce diarized output on a fresh deployment, batch requests must specify diarize_model=v2 or diarize_model=latest. diarize=true on its own is pinned to v1; on a 260514 deployment that does not have the v1 model on disk, /v1/listen?diarize=true returns a successful response with no speaker labels — consistent with Deepgram's longstanding behavior when a requested diarizer model is not present.

Existing deployments retain their v1 batch diarizer and continue to work without changes. To add v2 to an existing deployment, contact your Deepgram representative.

  • Batch Diarization v2 — A new batch diarization model with significantly improved speaker labeling, preferred 3.3× over v1 in side-by-side human evaluation. Strongest gains on contact-center audio (~80% reduction in median Confusion Error Rate vs. v1, ~60% at p95). Compatible with Nova-1, Nova-2, Nova-3, plus enhanced and base batch models; monolingual and multilingual. Not compatible with Whisper. The API response format is unchanged from v1. Batch-only; streaming diarization is unchanged. See Speaker Diarization for details.
  • New diarize_model Parameter — Opt into v2 by passing diarize_model=v2 (pin to v2) or diarize_model=latest (recommended; auto-upgrades to future diarizer iterations) on pre-recorded /v1/listen requests. Unrecognized values return 400 Bad Request. Streaming requests reject diarize_model and return 400; use diarize=true for streaming diarization. diarize=true on batch continues to route to v1 to preserve behavior for existing integrations.
  • General Improvements — Keeps our software up-to-date.
