谷歌发布 Gemini 4 Hydrogen：100 万 token 上下文，同步升级全球搜索与 Gemini 应用
Mountain View—谷歌 11 月 12 日发布 Gemini 4 Hydrogen，把 Gemini 4 系列带给所有用户，主打速度与效率，面向日常编程与智能体工作流。谷歌称，旗舰的 Gemini 4 Carbon 与 Gemini 4 Argon 擅长深度长程推理，Hydrogen 则为在多样工作流中快速执行而建。
定价方面，Hydrogen 在整个 100 万 token 上下文窗口内统一收费：输入每百万 token 1.50 美元，输出每百万 token 7.50 美元。它设有四档思考等级：low、medium、high（默认）与新增的 xhigh。谷歌称，按 Artificial Analysis 智力指数，Hydrogen 在默认 high 档得 51 分，高于 Argon 的 50 分，xhigh 档可达 54 分，且完成任务常快于同级模型。
上线范围覆盖开发者、企业与消费者各端：Google AI Studio 各档、Gemini API、Gemini for business、Gemini 应用、Google Search，以及 Google Antigravity 中面向 Google AI Pro 与 Ultra 订户的部分功能。谷歌称，Hydrogen 显著升级了 Search：能更好理解由多部分问题、拼写错误或高度具体要求组成的自然提问，并以升级的查询扩展技术连接更广的相关链接。Gemini in Google Sheets 也从 AI Pro 与 Ultra 订户开始接入。

Google Releases Gemini 4 Hydrogen: 1 Million-Token Context, Rolling Out to Search and the Gemini App Worldwide
MOUNTAIN VIEW — Google on November 12 introduced Gemini 4 Hydrogen, bringing its Gemini 4 family to everyone, with speed and efficiency for everyday coding and agentic workflows. Google said its frontier models, Gemini 4 Carbon and Gemini 4 Argon, excel at deep, long-horizon reasoning, while Hydrogen is built for rapid execution across diverse agentic workflows.
Hydrogen is priced flat across its entire 1 million-token context window at $1.50 per million input tokens and $7.50 per million output tokens. It offers four thinking levels — low, medium, high (the default) and a new xhigh tier. Google said Hydrogen surpasses Argon on the Artificial Analysis Intelligence Index at its default high setting, 51 to 50, reaching 54 at xhigh, while often completing tasks faster than models in its class.
Hydrogen is rolling out globally across Google AI Studio tiers, the Gemini API, Gemini for business, the Gemini app, Google Search, and, for Google AI Pro and Ultra subscribers, Google Antigravity. Google said Hydrogen significantly upgrades Search, better understanding natural questions with multiple parts, typos or highly specific requests, and widening the range of relevant links through improved query fan-out. Gemini in Google Sheets is also starting with AI Pro and Ultra subscribers.
