### 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.

### This Release Contains The Following Changes

- **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](/guides/formatting-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.
