Darkbloom
If a model page names Darkbloom in the provider table, that row is who served the tokens.
Updated 2026-09-27
Darkbloom is a host. OpenRouter’s provider page, openrouter.ai/provider/darkbloom, listed 8 models on 27 Sep 2026. The rates on that page were low: examples included about $0.018 / $0.09, $0.042 / $0.22, $0.05 / $0.70, and $0.075 / $0.50 per million tokens, on open models from several labs.
You do not create a Darkbloom account to use those rows. You call the model slug on OpenRouter. The provider object can prefer a host if you need this one specifically. If Darkbloom is down, allow_fallbacks on the default setting can move the call. Forcing only that provider will fail closed when it is down.
Read Darkbloom’s own terms from the link on the provider page before you send data you cannot share with an extra processor. ZDR is a separate switch. A cheap provider is not automatically a zero-retention provider.
