Google 发布 Gemini 4 Hydrogen，面向全平台开放
Google 这次发的是中端执行模型，走量那种，全平台都能调用。如果你在搭多智能体系统，可以拿它做执行层、配 Carbon 做编排，成本应该比旗舰低不少。做 Agent 开发的可以直接去 Gemini API 试试。
Google 推出 Gemini 4 Hydrogen，定位为能力强、速度快的中端模型，目标是让 Gemini 4 能力覆盖更广泛的用户和场景。
模型已上线 Google AI Studio、Gemini API、Gemini for business、Gemini 应用、Google Search，Google AI Pro 和 Ultra 付费订阅用户还可以在 Google Antigravity 中使用。
该推文指出，中端模型（如 Sonnet 与 Terra）正成为规模化多智能体系统的主力：Carbon 负责编排，Hydrogen 负责执行。这意味着 Gemini 4 Hydrogen 被定位为执行层的工作模型，而非单纯的旗舰替代品，开发者可在编排与执行分工的架构中直接调用于 Gemini API。
NEW: Google introduces Gemini 4 Hydrogen. It may not be obvious to many, but the mid-tier models (e.g., Sonnet & Terra) are increasingly becoming the workhorses for scaling multi-agent systems. So, Carbon for orchestration and Hydrogen for execution. Great naming, too. Logan Kilpatrick @OfficialLoganK Introducing Gemini 4 Hydrogen, an extremely capable and fast model built to bring Gemini 4 to everyone! Available to all tiers of Google AI Studio, Gemini API, Gemini for business, the Gemini app, Google Search, and paid Google AI Pro + Ultra subscribers in Google Antigravity. 🔗 View Quoted Tweet📊 4 ⚡
