      • quay.io/deepgram/onprem-billing:1.11.2

This Release Contains The Following Changes

  • GPU Required Configuration — New [health] section in engine.toml with gpu_required configuration option allows Engine to fail on startup if no GPU is detected. While Engine can run without a GPU, production deployments require one for acceptable performance. Set gpu_required = true to fail fast if no GPU is available, rather than running with severely degraded performance. Default: false.
  • General Improvements — Keeps our software up-to-date.

Important: This is the last release that will include onprem-* image tags. The Deepgram image repositories have been updated to reflect our “self-hosted” naming. Images should now be pulled from the self-hosted-* Quay repositories. Starting with the next release in September 2025, we will only publish new images to self-hosted-* repos, deprecating onprem-* repository variants.
