Google 生态里的通用对话助手：网页/Windows/macOS 三端覆盖，模型按订阅档位分流，「不训练你的邮箱原库，但训练回答过程里的摘要」是它最容易被误读的一行条款。

The general chat assistant inside the Google ecosystem: web, Windows and macOS covered, models split by subscription tier — “it won't train on your raw Gmail/Drive, but it does train on summaries produced while answering” is its most easily misread clause.

适合与不适合When to use it, when not to

适合已经在 Google 生态（搜索、Workspace、Chrome）里工作的人——联动是真实优势。在意训练用途就关 Keep Activity（只影响未来对话）；在意机密内容按官方提醒不要输入。要本机运行或自由换模型，它不合适——去看本地模型运行器与开源框架。

People already working inside the Google ecosystem (Search, Workspace, Chrome) — the integration is a real advantage. If training matters, turn off Keep Activity (future conversations only); per the official reminder, don't enter confidential content.

Not a fit for running locally or freely swapping models — see the local model runners and open-source frameworks.

出品属地Origin: 国外出品foreign-made　国外主体（网信办公示名单未见对应备案主体）。foreign entity (no matching filing entity in the CAC registry).
国内使用Direct access: 直连不可达direct blocked　gemini.google.com 大陆直连稳定超时（2026-10-20 同日两次 000）。gemini.google.com times out consistently from mainland (000 twice).
备案状态CAC filing: 未见于备案名单not in filing list：未见于网信办公示名单（2026-10-20 检索 13 批附件，https://www.cac.gov.cn/2024-04/02/c_1713729983803145.htm）；该产品未面向大陆公众提供服务，备案不适用。not in the CAC public registry (13 batch attachments searched 2026-10-20, https://www.cac.gov.cn/2024-04/02/c_1713729983803145.htm); the product does not serve the mainland public, so filing does not apply.

备案信息以网信办《生成式人工智能服务已备案信息》公示名单为准（按批次滚动更新，本站只抄编号不解读）；「大陆可直连」是本站从大陆网络直连实测的结果，不是厂商承诺。GitHub 类站点当日实测有波动，口径写在依据里。Filing status is quoted from the CAC public registry (updated batch by batch; this site copies the number and does not interpret it). "Direct access" is this site's own reachability measurement from a mainland network, not a vendor promise. GitHub-hosted sites fluctuated on the measurement day — the note says so.

模型与开放条件Model & openness: 模型家族官方 release notes 披露并按订阅档位分流：2026-10-13 条目写明 Gemini 4 Argon 面向 Google AI Pro & Ultra 订阅用户在全球推出；免费档与付费档可用模型不同，以 release notes 为准。
The model family is disclosed via official release notes and routed by subscription tier: the 2026-10-13 entry states Gemini 4 Argon rolling out globally to Google AI Pro & Ultra subscribers; free and paid tiers get different models — per the release notes.
运行位置Where it runs: 网页为主入口；桌面端有官方应用——Windows 应用（release notes 2026-09-10，Alt+Space 唤起）与 macOS 应用（2026-07-29 语音创作条目、2026-10-13 Antigravity 编码条目）；生成在 Google 云端处理。
Web is the main entry; official desktop apps exist — a Windows app (release notes 2026-09-10, Alt+Space to summon) and a macOS app (2026-07-29 voice-creation entry, 2026-10-13 Antigravity coding entry); generation is processed on Google's cloud.
本地文件Local files: 支持多模态输入与文件上传；官方隐私声明明确不直接拿 Gmail/Drive/Photos 原库训练，但回答过程中产生的摘要、摘录与推断会被用于训练（Connected Apps 个人化页）。
Supports multimodal input and file uploads; the official privacy notice states Google does not train directly on your Gmail/Drive/Photos source libraries, but summaries, excerpts and inferences produced during answering are used for training (Connected Apps personalization page).
关机后的任务Tasks after shutdown: 对话即时返回；Skills 功能（release notes 2026-09-30）是可复用的指令集、可自动匹配触发，但没有「关机续跑」形态的官方声明。
Chats return instantly; the Skills feature (release notes 2026-09-30) is a reusable instruction set with automatic matching/triggering, but there is no official statement of an "offline continuation" form.
工具与扩展Tools & extensions: Google 生态联动（搜索、Workspace、Chrome）是主卖点；Connected Apps 可接第三方工具（含 MCP server 工具，官方帮助页 16836988）；Gemini macOS 应用内置 Antigravity 编码 agent（2026-10-13）。研究线有 Deep Research 与 Deep Research Max（官方 blog 2026-04-21：基于 Gemini 3.1 Pro，支持 MCP、原生可视化与自定义来源）；图像线有 Nano Banana 2（Gemini 3.1 Flash Image，官方 blog 2026-02-26，支持图像生成与编辑）。
Google ecosystem integration (Search, Workspace, Chrome) is the main selling point; Connected Apps can connect third-party tools (incl. MCP server tools, official help page 16836988); the Gemini macOS app embeds the Antigravity coding agent (2026-10-13).
上下文与记忆Context & memory: 有记忆与个性化功能；Gems（定制指令）将被 Skills 取代并自动迁移（release notes 2026-09-30）。跨会话记忆的完整边界以官方帮助页为准。
Has memory and personalization; Gems (custom instructions) are being replaced by Skills and migrate automatically (release notes 2026-09-30). The full boundary of cross-session memory is per the official help pages.
权限与限制Permissions & limits: 官方 Gemini Apps 隐私声明（2026-10-13 更新）：Keep Activity 开启时提示、生成内容与反馈用于改进 Google 服务（含训练生成式模型）；关闭后未来对话不用于训练（除非提交反馈）；临时聊天与关闭活动记录时保留 72 小时、不用于训练；人工审核员会审阅部分数据——官方提醒勿输入机密信息。
Official Gemini Apps privacy notice (updated 2026-10-13): with Keep Activity on, prompts, generated content and feedback are used to improve Google services (incl. training generative models); with it off, future chats are not used for training (unless you submit feedback); temporary chats and activity-recording-off data are kept 72 hours and not used for training; human reviewers review some data — the official notice warns against entering confidential information.
适合什么任务Best for: 已在 Google 生态里工作的人——联动是真优势。在意训练就关 Keep Activity；在意机密内容按官方提醒不要输入。要本机跑模型或自由换模型，这类闭源云助手都不合适。
For people already working inside the Google ecosystem — the integration is a real advantage. For training concerns, turn off Keep Activity; for confidential content, follow the official warning and don't enter it. For running models locally or swapping models freely, closed cloud assistants like this are not suitable.

头号误解Top misconception

把「不直接训练 Gmail/Drive 原库」读成「你的对话内容不训练」——回答中产生的摘要与推断仍会被训练（官方明写）Reading "does not train directly on Gmail/Drive originals" as "your chats are not used for training" — summaries and inferences from answers are still used (official wording)
把 Keep Activity 与临时聊天混为一谈——两套机制，前者管未来对话训练，后者管留存与历史Confusing Keep Activity with temporary chat — two mechanisms: one governs future training, the other retention and history
把 API 条款套到消费应用——Gemini Apps 隐私声明与 Gemini API 附加条款是两份文件Applying API terms to the consumer app — the Gemini Apps Privacy Notice and the Gemini API Additional Terms are two documents
把 Deep Research 当成「一次搜索」——它基于 Gemini 3.1 Pro 做多步研究，2026-04-21 起支持 MCP 与自定义来源Treating Deep Research as "one search" — it runs multi-step research on Gemini 3.1 Pro and since 2026-04-21 supports MCP and custom sources

实测记录Measured runs

本档未跑对话任务集；能力结论来自官方文档，不评价回答质量。

This site has not completed measured runs. The coding-oriented test protocol is at protocols/coding/_protocol.md (the coding task suite does not apply to chat products).

第一次怎么用

1. 打开 Keep Activity 设置，确认未来对话是否用于训练；临时聊天保留 72 小时且不训练。 2. 研究线用 Deep Research / Deep Research Max（2026-04-21 起支持 MCP 与自定义来源），要求它给出来源表。 3. 图像线用 Nano Banana 2（2026-02-26 上线），先定用途再定风格。 4. 需要 Workspace 联动时，逐项确认 Connected Apps 的授权范围。 5. 大陆直连会稳定超时（2026-10-20 两次 000），需要自备网络路径。
