Google 发布 Gemini 4 Carbon，面向复杂长链任务的旗舰模型
Google 把自家最强模型做成了分层产品：Argon 管日常活儿，Carbon 专门啃多步调试和科研这种硬骨头。做智能体和复杂工程的开发者可以试试 API，科研人员还有 6 个月免费申请，和直接上 Ultra 订阅比先薅这个更划算。
Google 宣布 frontier 模型 Gemini 4 Carbon 正式上线，定位是处理复杂、长链路任务，包括智能体工作流、软件工程、网络安全和科学推理等场景。定位上与 Gemini 4 Argon 形成分层：Argon 适合大多数软件工程和知识工作，Carbon 专门应对多步调试、开放式科学研究这类把模型推到极限的难题。
可用渠道分三类：消费者可通过 Gemini App 和 Search 的 AI Mode 使用，但需要 Google AI Ultra 订阅；开发者和企业通过 Google AI Studio、Android Studio 的 API 以及 Antigravity 接入；科研人员可申请 6 个月免费使用。网络安全防御者可申请加入 Fairwind Program 获取面向安全场景的 Carbon 访问权限。
官方演示中，Carbon 将鸣禽研究转化为一个可交互的 3D 模拟，实时合成六个鸟种的鸣叫声，展示推理与编码结合的能力。这一发布延续了 frontier 模型按任务难度分层定价提供的思路，开发者需要根据任务复杂度在 Carbon 和 Argon 之间做选择。
Our strongest frontier model, Gemini 4 Carbon, is now available. Built for deeply complex, long-horizon workflows that push a frontier model’s intelligence, Carbon delivers frontier performance in agentic workflows across complex knowledge work, software engineering and web development, cybersecurity, and scientific reasoning. While Gemini 4 Argon remains the ideal model for the majority of software engineering and knowledge work, Carbon steps in for your hardest tasks that push a model to its limits — from complex, multi-step debugging to open-ended scientific research. Available starting today: — Consumers: use it in the @GeminiApp and AI Mode in Search for Google AI Ultra subscribers — Developers and Enterprises: build via the API in @GoogleAIStudio and @AndroidStudio , Google @Antigravity for Google AI Ultra subscribers, and Gemini for business — Scientists and Researchers: apply for a chance to get 6 months free via @Antigravity — Cybersecurity Defenders: apply to join the Fairwind Program for access to Carbon for cyber Watch how Carbon brings reasoning and coding together, turning avian research into an interactive 3D simulation of a songbird’s vocal organ that synthesizes the sounds of six bird species live.
