Questions

Which should I use, DeepSeek: R1 0528 or NVIDIA: Nemotron 3 Ultra?

Is DeepSeek: R1 0528 or NVIDIA: Nemotron 3 Ultra cheaper?

The current cheapest TrustedRouter route is $2.79575/1M for DeepSeek: R1 0528 and $2.79575/1M for NVIDIA: Nemotron 3 Ultra. The comparison uses current catalog prices and updates as provider pricing changes.

Is DeepSeek: R1 0528 or NVIDIA: Nemotron 3 Ultra faster?

Current measured p50 time to first token is not enough data for DeepSeek: R1 0528 and not enough data for NVIDIA: Nemotron 3 Ultra. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test DeepSeek: R1 0528 and NVIDIA: Nemotron 3 Ultra with the same API?

Yes. Use the same OpenAI-compatible TrustedRouter base URL and API key, then change only the model id between deepseek/deepseek-r1-0528 and nvidia/nemotron-3-ultra-550b-a55b. This makes side-by-side evals possible without maintaining two provider integrations.
