bpm/seed-2.0How BytePlus ModelArk billing works with kRouter
BytePlus ModelArk gives you free starting credits, then bills per token. kRouter tracks the remaining quota and fails over to another provider before you hit a wall. kRouter authenticates it via apikey. 7 models are routable as byteplus/<model>.
Through kRouter, BytePlus ModelArk serves chat and code completion. Requests reach it through the same local OpenAI-compatible endpoint as every other provider, so switching to or from BytePlus ModelArk is a one-line model change in your client rather than a rewrite.
Free credits for new accounts. Access to Seed 2.0, Kimi K2 Thinking, GLM 4.7, GPT-OSS-120B models.
