Providers serving this model

Sorted by lowest combined prompt and completion price. Use "provider": {"sort": "throughput"} in the request body (or append :nitro to the model id) to route to the fastest provider instead.

Trust boundary: TR router attestation verifies the TrustedRouter gateway only. Provider policy separately describes the upstream model host's retention, confidential compute, and E2EE posture. Company country is separate from inference location. Weight formats are source-backed declarations, not per-request proofs.

TrustedRouter exposes chat-capable models from its configured API Catalog key as Standard routes. NVIDIA requires an NVIDIA AI Enterprise entitlement for production deployments. NVIDIA does not publish hosted preview token rates, so TrustedRouter uses a conservative fallback price and excludes these routes from price indexing.

Questions

What model ID should I use for NVIDIA: Nemotron 3 Ultra?

Use nvidia/nemotron-3-ultra-550b-a55b as the model field with the TrustedRouter OpenAI-compatible API. Credits routing and provider fallback happen behind that model ID.

Which providers serve NVIDIA: Nemotron 3 Ultra?

TrustedRouter currently lists Baseten, Fireworks AI, Weights & Biases, DeepInfra, and NVIDIA NIM for NVIDIA: Nemotron 3 Ultra. Provider availability and routing eligibility can change as catalog and health data update.

How much does NVIDIA: Nemotron 3 Ultra cost through TrustedRouter?

The current lowest Credits input price is $0.5275/1M and the lowest Credits output price is $2.26825/1M. Prices are per one million tokens and come from the current route catalog.

How do I require zero data retention for NVIDIA: Nemotron 3 Ultra?

Set provider.min_privacy to zdr on the request. TrustedRouter considers only routes with a recorded zero-data-retention posture and fails closed if no eligible route remains.
