> Deepgram Self-Hosted release 261110 rejects unsupported language hints on Nova-3 Multilingual and Flux STT, changes how to verify callbacks, speeds up preloaded models, and improves Flux TTS shutdown and Portuguese formatting.

## Deepgram Self-Hosted November 2026 Release (261110)

### Container Images (release 261110)

* `quay.io/deepgram/self-hosted-api:release-261110`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-api:1.192.58-1`

* `quay.io/deepgram/self-hosted-engine:release-261110`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-engine:3.142.0-1`

  * Minimum required NVIDIA driver version: `>=580`, **open** kernel module flavor. See [Drivers and Containerization Platforms](/docs/drivers-and-containerization-platforms) for installation and verification steps.

* `quay.io/deepgram/self-hosted-license-proxy:release-261110`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-license-proxy:1.11.2-1`

* `quay.io/deepgram/self-hosted-billing:release-261110`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-billing:1.15.1-1`

### FIPS 140-3 Images

FIPS 140-3 images are available for all four self-hosted services, published under the `-fips` tag suffix:

* `quay.io/deepgram/self-hosted-api:release-261110-fips`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-api:1.192.58-1-fips`

* `quay.io/deepgram/self-hosted-engine:release-261110-fips`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-engine:3.142.0-1-fips`

* `quay.io/deepgram/self-hosted-license-proxy:release-261110-fips`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-license-proxy:1.11.2-1-fips`

* `quay.io/deepgram/self-hosted-billing:release-261110-fips`
  * Equivalent image to:
    * `quay.io/deepgram/self-hosted-billing:1.15.1-1-fips`

These images run OpenSSL's FIPS 140-3 validated cryptographic provider. Enable FIPS by setting `[fips] mode = "enabled"` in each service's configuration. FIPS mode should be enabled only on the `-fips` images; the standard images do not include the FIPS provider. See [FIPS-Compliant Deployment](/docs/fips-compliant-deployment) for setup and configuration details.

### This Release Contains The Following Changes

* **Nova-3 Multilingual Language Hints (action required)** — a `language_hint` on a multilingual model that does not support hints now returns HTTP 400 `INVALID_QUERY_PARAMETER`. Previously the hint was accepted but had no effect. Before upgrading, remove `language_hint` from requests to multilingual models that don't support hints.
* **Flux STT Language Hint Validation** — an unsupported `language_hint` on `/v2/listen` now returns HTTP 400 when the stream is opened, and a `Configure` message with one returns `ConfigureFailure` and keeps the stream's existing configuration. Previously the stream failed after the first audio.
* **Callback Verification** — the `dg-token` header is no longer a supported method to verify that callback requests come from Deepgram. The API still sends it in this release, but if your callback server checks for `dg-token`, switch to Basic Auth by putting credentials in the callback URL, such as `https://username:password@example.com/callback`. For Speech-to-Text, you can also pass a secret with [Extra Metadata](/docs/extra-metadata), such as `extra=callback_secret:YOUR_SECRET_VALUE`, and reject any callback whose `metadata.extra.callback_secret` is missing or doesn't match. See [Authenticating Callback Requests](/docs/callback#authenticating-callback-requests) for details.
* **Preloaded Models Use Half Precision** — on GPUs that support it, models loaded at startup through `[preload_models]` now load in half precision, matching models loaded on demand. This reduces GPU memory use and improves inference speed for preloaded models.
* **Flux TTS Graceful Shutdown** — Engine now lets in-progress `/v2/speak` WebSocket sessions finish before shutting down, matching `/v2/listen`.
* **Formatting Improvements** — Portuguese "meia" is now rendered as `6` inside spelled-out digit strings.
* **General Improvements** — License Proxy and Billing rebuilt with updated dependencies. Keeps our software up-to-date.
