Claude（闭源 API）Claude (closed API)闭源模型 · 官方规格快照 · 带复核周期closed model · official spec snapshot · with review cycle

闭源旗舰线（agentic 编码与企业向）：官方模型总览是规格真相源；官方文档将模型 ID 定义为固定版本，而非持续更新的别名；选型时应核对具体 ID。A closed flagship line (agentic coding and enterprise): the official model overview is the spec source of truth; model IDs are pinned snapshots, not evergreen pointers (stated in official docs) — match versions by ID.

怎么用得到How you can use it：API 与 Claude 订阅；权重不开源。API and Claude subscription; weights are not open.

权重不开源，本站无量化对比；编码工具形态的 Claude Code / Claude 档案在 AI 工具站。No open weights, so no quantisation coverage here; the Claude Code / Claude product forms are carded on the tools site.
