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 Nano 30B A3B or Z.ai: GLM 5.1?

Is NVIDIA: Nemotron 3 Nano 30B A3B or Z.ai: GLM 5.1 cheaper?

The current cheapest TrustedRouter route is $0.2625/1M for NVIDIA: Nemotron 3 Nano 30B A3B and $4.263/1M for Z.ai: GLM 5.1. The comparison uses current catalog prices and updates as provider pricing changes.

Is NVIDIA: Nemotron 3 Nano 30B A3B or Z.ai: GLM 5.1 faster?

Current measured p50 time to first token is 631 ms for NVIDIA: Nemotron 3 Nano 30B A3B and 1079 ms for Z.ai: GLM 5.1. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test NVIDIA: Nemotron 3 Nano 30B A3B and Z.ai: GLM 5.1 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-nano-30b-a3b and z-ai/glm-5.1. This makes side-by-side evals possible without maintaining two provider integrations.
