Is deepseek-v4-flash or deepseek-v4-pro cheaper on RelayRouter?
Compare the cheapest group of each: deepseek-v4-flash is served by "DeepSeek" (¥1.1 (about $0.162) per 1M input tokens, ¥4.4 (about $0.647) per 1M output tokens; off-peak; ×2 on weekdays 09:00 to 12:00 and 14:00 to 18:00 Beijing time) and deepseek-v4-pro by "DeepSeek" (¥4.95 (about $0.728) per 1M input tokens, ¥14.85 (about $2.18) per 1M output tokens; off-peak; ×2 on weekdays 09:00 to 12:00 and 14:00 to 18:00 Beijing time). 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?
No. It compares availability, protocols and price on RelayRouter. Run your own evaluation prompts through both models; failed requests are not billed.
Rates are indicative; the console shows the authoritative rate at request time. See pricing and the full model list.
