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, Cosmos3-Super-Reasoner or Z.ai: GLM 5.2?

Is Cosmos3-Super-Reasoner or Z.ai: GLM 5.2 cheaper?

The current cheapest TrustedRouter route is $0.422/1M for Cosmos3-Super-Reasoner and $2.2999/1M for Z.ai: GLM 5.2. The comparison uses current catalog prices and updates as provider pricing changes.

Is Cosmos3-Super-Reasoner or Z.ai: GLM 5.2 faster?

Current measured p50 time to first token is not enough data for Cosmos3-Super-Reasoner and 1330 ms for Z.ai: GLM 5.2. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test Cosmos3-Super-Reasoner and Z.ai: GLM 5.2 with the same API?

Yes. Use the same OpenAI-compatible TrustedRouter base URL and API key, then change only the model id between nvidia/Cosmos3-Super-Reasoner and z-ai/glm-5.2. This makes side-by-side evals possible without maintaining two provider integrations.
