谷歌发布最新前沿模型 Gemini 4 Carbon：性能再升级，但你暂时还用不上

在今年早些时候暂缓发布前沿 AI 模型之后，谷歌现在似乎急于证明自己的实力。就在推出 Gemini 4 Argon 仅仅两周后，谷歌又宣布了 Gemini 4 Carbon。这并不是大家一直在等待的 Flash 等级轻量模型，而是对 Argon 的进一步改良；且与 Argon 类似，谷歌正在对其进行分阶段推送，全面开放可能还需要一段时间。

如果你觉得这段话似曾相识，请随时打断我：谷歌表示，其最新 AI 模型在编程、Agent 任务以及科学分析方面跨越了新的门槛。事实上，它的能力过于强劲，以至于谷歌目前还不能直接开放供所有人使用。

据报道，Gemini 4 Carbon 在网络安全应用领域取得了显著进展。谷歌称该模型在漏洞检测、验证和修复方面实现了“重大飞跃”。与 Argon 相比，Carbon 生成无漏洞代码的概率提升了一倍。与此同时，Chrome 团队声称，与非谷歌模型相比，Carbon 在生成“高质量”安全补丁方面的能力高出 10 倍。谷歌还指出，Carbon 在 WebDev Arena 上的评分提高了 89 分，目前在排行榜上位列第四。

谷歌提供了一些数据来支持这些评估（见下文），展示了 Carbon 名列榜首的成绩。虽然谷歌将 Carbon 定位为一款完全全新的模型，但在外界看来，它更像是 Argon 的后训练（post-training）升级版本。这两款模型有许多共通之处，但在谷歌运行的每一项测试中，Carbon 确实都以微弱优势超越了 Argon。此外，这款新模型在几乎所有测试中也击败了 GPT-6 Astra、Claude Opus 5.5 和 Claude Fable 5.1。当然，基准测试并不能代表全部，值得注意的是，所有前沿模型在这些测试中的得分都处于十分接近的区间，Carbon 与竞争对手之间的差距其实只有微弱的几分。

It’s almost like Google’s got something to prove after taking a break from releasing new frontier AI models earlier this year. Just two weeks after rolling out Gemini 4 Argon, Google has announced Gemini 4 Carbon. This isn’t the Flash model equivalent we’ve been waiting for but, rather, is an improvement on Argon, and like that model, Google is working on a staged release that could take a while.

Stop me if you’ve heard this one before: Google says its latest AI model reaches a new threshold in coding, agentic tasks, and scientific analysis. It’s so capable, in fact, that Google can’t let you use it just yet.

Gemini 4 Carbon reportedly makes big gains in cybersecurity applications. Google says the model shows a “significant leap” in vulnerability detection, validation, and remediation. Carbon is also apparently twice as likely to generate code that is free of vulnerabilities versus Argon. Meanwhile, the Chrome team claims that Carbon is 10 times better at generating “high-quality” patches compared to non-Google models. Google also notes that Carbon has increased its score by 89 points on WebDev Arena, now ranking at number four on the leaderboard.

Google has some numbers to support these vague assessments (below), showing Carbon at the top of the charts. Google positions Carbon as a totally new model, but for all we know, it could be a post-training upgrade of Argon. The two models have a lot in common, but Carbon does best Argon by slim margins in every test Google has given it. Its new model also beats GPT-6 Astra, Claude Opus 5.5, and Claude Fable 5.1 in almost every test. Benchmarks don’t tell the whole story, of course, and it’s notable that every frontier model scores in the same neighborhood in these tests. The gap between Carbon and the competition is just a few points.
