Google发布Gemini 4 Hydrogen取代Flash 3.8
Google rolls out Gemini 4 Hydrogen, finally replacing 3.8 Flash
Google is continuing its elemental AI naming scheme with the new Gemini 4 Hydrogen. These names are less descriptive than the Pro/Flash monikers of earlier releases, but Hydrogen's purpose is clear: It replaces the faster, more economical Flash models most people in Google's ecosystem use.
谷歌继续其元素AI命名方案，推出了新的Gemini 4 Hydrogen。这些名称不如早期版本的Pro/Flash那样具有描述性，但Hydrogen的目的很明确：它取代了谷歌生态系统中大多数人使用的更快、更经济的Flash模型。
With Google's recent Argon and Carbon releases, the rollout was staged and began with cybersecurity researchers. Even when general availability began, Google restricted access to users paying for its most expensive AI subscription. The limits for Hydrogen are much more relaxed, with access beginning immediately. This model has replaced Gemini 3.8 Flash across the company's products.
随着谷歌最近发布Argon和Carbon，推出是分阶段进行的，最初面向网络安全研究人员。即使开始全面可用，谷歌也将访问权限限制在支付其最昂贵AI订阅费用的用户身上。Hydrogen的限制要宽松得多，用户可以立即获得访问权限。该模型已在其公司的产品中取代了Gemini 3.8 Flash。
Google claims that Hydrogen represents a major improvement versus the previous Flash model. It runs in one of four thinking levels (low, medium, high, and the new xhigh), and even in high mode, it's 2.5 times faster than Flash 3.8. Plus, it reduces "fabricated claims" by more than 5x, according to Google's analysis. Users will also see gains in code generation, with Hydrogen more than tripling 3.8 Flash's score in Terminal-Bench. In some cases, Hydrogen even trades blows with Argon. It managed a score of 54 in the popular Artificial Analysis Intelligence Index with xhigh mode versus 50 for Argon.
谷歌声称，与之前的Flash模型相比，Hydrogen代表了重大改进。它可以运行在四种思维级别之一（低、中、高以及新增的xhigh），即使在高级模式下，它的速度也比Flash 3.8快2.5倍。此外，根据谷歌的分析，它将“捏造声明”减少了5倍以上。用户在代码生成方面也将看到提升，Hydrogen在Terminal-Bench中的得分是3.8 Flash的三倍以上。在某些情况下，Hydrogen甚至能与Argon相匹敌。它在流行的Artificial Analysis Intelligence Index中以xhigh模式获得了54分，而Argon为50分。
