Questions

Is gemini-3.8-flash or gemini-3.7-flash cheaper on RelayRouter?

Compare the cheapest group of each: gemini-3.8-flash is served by "Gemini Vertex Official" (settlement rate ¥5.4 per $1 of standard usage, about 21% below the ¥6.8/$ market reference) and gemini-3.7-flash by "Gemini Fast" (settlement rate ¥2.72 per $1 of standard usage, about 60% below the ¥6.8/$ market reference). Settlement rates apply to the provider's standard usage, so a model with a higher official price can still cost more at a lower rate.

Can I switch between the two without changing code?

If both models sit in groups with the same protocol you only change the model name. If the protocols differ, point the matching SDK at https://relayrouter.io; the base URL and key handling stay the same.

Does this page compare output quality?
