国产闭源主力：对话产品「豆包」与 API「Doubao-Seed」同族两条线；服务在网信办备案（Beijing-YunQue-20230821，豆包大模型=云雀更名，官方备案公示页确认）。代次更替快，本站卡带核验日与复核周期。The domestic closed flagship: the Doubao consumer app and the Doubao-Seed API are two lines of one family; the service is CAC-filed (Beijing-YunQue-20230821 — Doubao LLM is the renamed YunQue, confirmed on the official filing-disclosure page). Generations churn fast, so the card carries a check date and review interval.

怎么用得到How you can use it：火山方舟 API 与豆包 App；权重不开源。Volcengine Ark API and the Doubao app; weights are not open.

权重不开源，本站无量化对比；对话产品三要素轻档案在 AI 工具站（对话问答区）。No open weights, no quantisation coverage; the three-essentials light entry for the app lives on the tools site (chat section).
