Gemini 4 Carbon 将仅向 Google AI Ultra 订阅用户和 API 开放
Google AI Studio 的升级弹窗泄露了 Gemini 4 Carbon 的访问门槛:要么订阅 Ultra,要么用 API Key。对开发者来说走 API 就能提前用上,普通用户则要掏 Ultra 订阅费,想尝鲜的可以先准备好 API Key。
根据 Google AI Studio 更新后的升级提示弹窗,Gemini 4 Carbon 需要用户持有 Google AI Ultra 订阅计划,或提供 Gemini API Key 才能使用。弹窗原文写着"Gemini 4 Carbon needs a Google AI Ultra plan or a Gemini API key"。
这则提示说明 Carbon 至少会在 Ultra 订阅和 API 两个渠道率先放出,而不是一开始就在免费版 Gemini 中提供。AI Studio 的升级弹窗此前也多次提前泄露过未正式发布的模型信息,这次更新被视为 Gemini 4 Carbon 发布临近的信号。
对普通免费用户来说,新模型上线初期可能无法直接使用,需要付费订阅 Ultra 或走 API 调用。这种付费墙策略与 Google 此前对部分高端模型的分级访问方式一致,开发者则可以通过 API Key 提前接入测试。
