Google 发布 Gemini 4 Carbon，面向 AI Ultra 订阅用户开放
Google 把最强模型 Gemini 4 Carbon 推给了 AI Ultra 订阅用户，官方建议难任务用 Carbon、复杂任务用 Argon。做长程推理、3D 原型或文档转报告的可以立刻在 gemini.google 试试，和 Argon 跑同一批任务对比效果。
Google 宣布新一代旗舰模型 Gemini 4 Carbon 从今日起向 Google AI Ultra 订阅用户开放，覆盖桌面、移动和网页端。官方将其定位为目前最强的模型，主打深度推理和长程多步任务处理。
按官方描述，Carbon 在三个方向有明确改进：复杂任务输出更完整可靠；能将密集的数据和文档转化为演示文稿、表格和可直接使用的报告，分析精度更高；空间理解能力增强，可生成 Web 应用、原型和 3D 场景，适合 3D 与 UI 设计工作。官方还给出与上代模型的分工建议：Argon 适合复杂任务，Carbon 用于最难的问题。
对订阅 AI Ultra 的重度用户来说，这条推送意味着无需换工具就能在现有 Gemini 入口用到新模型；对开发者而言，空间理解和长程推理的增强指向 3D、原型生成和智能体工作流场景，可与 OpenAI、Anthropic 的旗舰模型直接对比测试。
Starting today, our next frontier model Gemini 4 Carbon is rolling out to Google AI Ultra subscribers on desktop, mobile, and web at gemini.google It’s our strongest model, built to reason deeply through your most complex work: ✅ Get more thorough, reliable outputs on your toughest tasks ✅ Turn dense data and docs into polished presentations, spreadsheets, and ready-to-use reports with more precise analysis ✅ Create web apps, prototypes, and 3D scenes with stronger spatial understanding for 3D and UI design Google @Google Gemini 4 Carbon is now available. It’s our strongest model, built to dig deeper, handle long-horizon tasks, and multi-step reasoning. If Argon is great for complex tasks, Carbon is the model you bring in for your hardest problems.
