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, Jina AI: Jina Embeddings v5 Omni Small or Z.ai: GLM 5.1?

Is Jina AI: Jina Embeddings v5 Omni Small or Z.ai: GLM 5.1 cheaper?

The current cheapest TrustedRouter route is $0.05275/1M for Jina AI: Jina Embeddings v5 Omni Small and $4.2833/1M for Z.ai: GLM 5.1. The comparison uses current catalog prices and updates as provider pricing changes.

Is Jina AI: Jina Embeddings v5 Omni Small or Z.ai: GLM 5.1 faster?

Current measured p50 time to first token is not enough data for Jina AI: Jina Embeddings v5 Omni Small and 1200 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 Jina AI: Jina Embeddings v5 Omni Small and Z.ai: GLM 5.1 with the same API?

Both use the same TrustedRouter base URL and API key. At least one of them is not a chat model, so the request can differ as well as the model id: the API docs list the route for each kind of model.
