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 Ultra or Z.ai: GLM 4.7 Flash?

Is NVIDIA: Nemotron 3 Ultra or Z.ai: GLM 4.7 Flash cheaper?

The current cheapest TrustedRouter route is $2.8485/1M for NVIDIA: Nemotron 3 Ultra and $0.4853/1M for Z.ai: GLM 4.7 Flash. The comparison uses current catalog prices and updates as provider pricing changes.

Is NVIDIA: Nemotron 3 Ultra or Z.ai: GLM 4.7 Flash faster?

Current measured p50 time to first token is 921 ms for NVIDIA: Nemotron 3 Ultra and not enough data for Z.ai: GLM 4.7 Flash. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test NVIDIA: Nemotron 3 Ultra and Z.ai: GLM 4.7 Flash 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-ultra-550b-a55b and z-ai/glm-4.7-flash. This makes side-by-side evals possible without maintaining two provider integrations.
