Is claude-sonnet-4-6 or claude-opus-5-5 cheaper on RelayRouter?
Compare the cheapest group of each: claude-sonnet-4-6 is served by "Claude Fast" (settlement rate ¥1.2 per $1 of standard usage, about 82% below the ¥6.8/$ market reference) and claude-opus-5-5 by "Claude" (settlement rate ¥2 per $1 of standard usage, about 71% below the ¥6.8/$ 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?
