The current cheapest TrustedRouter route is $0.45365/1M for Google: Gemma 4 31B and $1.055/1M for TrustedRouter Mev 1.0. The comparison uses current catalog prices and updates as provider pricing changes.

Is Google: Gemma 4 31B or TrustedRouter Mev 1.0 faster?

Current measured p50 time to first token is not enough data for Google: Gemma 4 31B and not enough data for TrustedRouter Mev 1.0. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test Google: Gemma 4 31B and TrustedRouter Mev 1.0 with the same API?

Yes. Both take the same request on POST /api/alpha/decide, with the same TrustedRouter base URL and API key, so a side-by-side eval changes only the model id between google/gemma-4-31b-it and trustedrouter/mev-1.0. TrustedRouter Mev 1.0 does not take chat requests.
