Questions

Which should I use, nvidia/Gemma-4-31B-IT-NVFP4 or Z.ai: GLM 5.3?

Is nvidia/Gemma-4-31B-IT-NVFP4 or Z.ai: GLM 5.3 cheaper?

The current cheapest TrustedRouter route is $0.5697/1M for nvidia/Gemma-4-31B-IT-NVFP4 and $4.2833/1M for Z.ai: GLM 5.3. The comparison uses current catalog prices and updates as provider pricing changes.

Is nvidia/Gemma-4-31B-IT-NVFP4 or Z.ai: GLM 5.3 faster?

Current measured p50 time to first token is 1241 ms for nvidia/Gemma-4-31B-IT-NVFP4 and 1321 ms for Z.ai: GLM 5.3. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test nvidia/Gemma-4-31B-IT-NVFP4 and Z.ai: GLM 5.3 with the same API?

Yes. Use the same OpenAI-compatible TrustedRouter base URL and API key, then change only the model id between google/gemma-4-31b-it-nvfp4 and z-ai/glm-5.3. This makes side-by-side evals possible without maintaining two provider integrations.
