The price comparison adds each route's rate for one million input tokens and one million output tokens; your cost depends on your input/output mix. Prices and live route measurements can change. Use the monthly reports when you need a stable evidence window, then run a small task-specific eval before choosing a production default.

Production choice

Pick a default model. Keep fallback enabled.

TrustedRouter is useful when you know the model you want, but still need provider rollover, budget limits, usage records, and a prompt path you can verify.

Questions

Which should I use, NVIDIA: Nemotron 3 Super or OpenAI: GPT-4o?

NVIDIA: Nemotron 3 Super has the lower published input-plus-output rate, more Credits provider routes and the larger context window. There is not enough recent probe data to compare speed.

Is NVIDIA: Nemotron 3 Super or OpenAI: GPT-4o cheaper?

The current cheapest TrustedRouter route is $0.511675/1M for NVIDIA: Nemotron 3 Super and $13.1875/1M for OpenAI: GPT-4o. The comparison uses current catalog prices and updates as provider pricing changes.

Is NVIDIA: Nemotron 3 Super or OpenAI: GPT-4o faster?

Current measured p50 time to first token is 1782 ms for NVIDIA: Nemotron 3 Super and not enough data for OpenAI: GPT-4o. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test NVIDIA: Nemotron 3 Super and OpenAI: GPT-4o with the same API?

Yes. Use the same OpenAI-compatible TrustedRouter base URL and API key, then change only the model id between nvidia/nemotron-3-super-120b-a12b and openai/gpt-4o. This makes side-by-side evals possible without maintaining two provider integrations.
