# Google Gemini：模型数据来源
|
||
|
||
核验轮次：2026-10-03。这里的日期是访问/复核日期，不是模型发布日期。
|
||
|
||
## 对应配置
|
||
|
||
- [google.json](../../../compute/providers/google.json)
|
||
- [google.json](../../../compute/model-specs/google.json)
|
||
|
||
## 官网证据
|
||
|
||
### google-models
|
||
|
||
- 入口：[google-models](https://ai.google.dev/gemini-api/docs/models)
|
||
- 类型：`official-doc`；当前读取状态：`fetched`；地域/接入面：`google 官方入口；具体地域与接入面待该页面逐字段确认`。
|
||
### google-embedding
|
||
|
||
- 入口：[google-embedding](https://ai.google.dev/gemini-api/docs/embeddings)
|
||
- 类型：`official-doc`；当前读取状态：`fetched`；地域/接入面：`Gemini Developer API 原生 Embedding 2；输入限额与输出向量维度`。
|
||
### google-tts
|
||
|
||
- 入口：[google-tts](https://ai.google.dev/gemini-api/docs/models/gemini-3.8-flash-tts)
|
||
- 类型：`official-doc`；当前读取状态：`fetched`；地域/接入面：`Gemini Developer API 原生 TTS；输入和输出分别限额`。
|
||
### google-transcribe
|
||
|
||
- 入口：[google-transcribe](https://ai.google.dev/gemini-api/docs/models/gemini-3.5-transcribe)
|
||
- 类型：`official-doc`；当前读取状态：`fetched`；地域/接入面：`Gemini Developer API 原生转写，客户端协议适配另核`。
|
||
|
||
## 核验结论与边界
|
||
|
||
Embedding 2 的最大输入 8192 和推荐维度 768/1536/3072 已再次核对。新 TTS 的输入 8192 与输出 16384 是分别的限制，不用 output<=input 判断错误。新音频协议只有共享规格，不能宣称客户端已适配。
|
||
|
||
状态 `partial` 仅表示列出的字段已核实；不能推断整条配置、价格、账号权限或真实模型调用都已验收。`pending` 没有已核字段；`historical` 只作历史兼容参考。路由 tier/priority、产品标签和默认选择属于本仓策略，不伪装成官网数据。
|
||
|
||
## 当前配置与字段级核验
|
||
|
||
下表“计价”是配置的 inputPrice/outputPrice 字段快照，不统一代表 token 单价；按张、按秒、search unit 和兼容占位值需查看原配置 extra.pricingNotes 与官网说明。未列为已核字段的数值仍待核实。
|
||
|
||
### compute/providers/google.json
|
||
|
||
接入面配置快照：`google-generative-ai`；端点：`https://generativelanguage.googleapis.com/v1beta`；币种：`USD`。这些平台字段不是整条官网验收结论，核验边界见上文。

|
||
|
||
## 待核实项与更新步骤
|
||
|
||
1. 按模型 ID 打开上面的官方页面，定位对应型号/地域/接入面，不以页脚日期或目录存在代替参数证明。
|
||
2. 先核对上下文、单次输出、推理和多模态输入，再核对计价单位；套餐可用性单独核对。
|
||
3. 修改 canonical JSON、对应 Provider 副本及本页中实际变化的记录；只更新真实核实字段及来源，不将 pending 批量改成 partial。
|
||
4. 用 `node scripts/validate-sources.mjs --fingerprints` 查看新指纹；同步本页受影响的表格行。
|
||
5. 运行 `npm run validate` 与 `npm test`，必要时在已授权账号做聚焦调用；无实测时保留限制说明。
