Gemini（闭源 API）Gemini (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

Google 的闭源旗舰线；与开放权重的 Gemma 是两条线，别混。选型注意官方「预览版」标注——预览意味着规格与价格都可能变，本站只抄快照。Google's closed flagship line; distinct from the open-weight Gemma line — do not conflate them. Note the official "preview" labels: preview means specs and prices may change; this site only snapshots.

怎么用得到How you can use it：API（Gemini API / Vertex）与 Gemini 应用订阅；权重不开源（开放权重的是另一条 Gemma 线）。API (Gemini API / Vertex) and the Gemini app subscription; weights are not open (the open-weight line is Gemma).

开放权重侧本站收录 Gemma 4（谱系卡 + 量化对比）；Gemini 系不开权重。On the open-weight side this site covers Gemma 4 (family card + quantisation); the Gemini line ships no weights.
