Category: Development & Code · Agent & RAG frameworks
Features
Volcengine Ark is ByteDance’s platform for model APIs and agents. It includes Doubao-Seed-Evolving for text and code, Seedream for images and Seedance for video. Knowledge bases and other services complement model calls. Text, images, video and speech follow different billing rules.
For Doubao-Seed-Evolving, the text pricing table shows CNY 0.006 per 1,000 input tokens and CNY 0.03 per 1,000 output tokens in the specified price band. Usage is billed hourly. The 500,000 free tokens are an allowance for certain text models, not a blanket free offer for every image, video or speech model. Agent Plan and other subscriptions or capacity offers are separate.
