Why we picked it

Google 把 Gemini 4 Carbon 先给了 Ultra 订阅和 API 用户，Pro 档还没份。想第一时间试的开发者可以直接走 API 接入，普通用户得考虑要不要升级到最高档，或者等官方后续放开。

Google 官方宣布 Gemini 4 Carbon 的推出计划，首批面向 Gemini Ultra 订阅用户开放，同时提供 API 接入。这意味着普通用户暂时无法在 Gemini Pro 档位上使用该模型。公告发布在 X 平台，来源为科技爆料账号 testingcatalog。

从开放策略看，Google 选择了订阅分层加 API 双通道的常见发放方式：付费最高档的 Ultra 用户优先体验，开发者则可以通过 API 集成。文中提到 Pro 订阅用户希望也能获得使用权限，说明 Google 尚未明确该模型向低档位订阅铺开的时间表。对开发者而言，API 可用性意味着可以将 Gemini 4 Carbon 接入自有产品进行测试，而无需订阅消费级套餐。

Chinese contentAnthropic 发布 Claude Fable 5.2，登顶 Artificial Analysis 智能指数

Anthropic 的新旗舰模型，科学推理和编程基准刷了一堆纪录，比如 HLE-Diamond 拿到 80%。有意思的是调低 effort 档反而更划算，输出 token 用得更少还能赢 Opus 5.5。做科学计算、代码开发的团队值得看下这笔成本账。

Agent Arena data shows 66% cost gap in hour-long agent tasks

For hour-long agent workloads, the cheapest model is not automatically the right one: Claude Opus 5.5 scores higher but costs twice as much per hour as Gemini 4 Carbon. Teams running long-horizon agents can use these per-hour cost and time figures to match model choice to budget and quality needs. The 55-minute spread among frontier models also suggests task duration, not just accuracy, should enter model selection criteria.

Gemini 4 Carbon leads cost scaling in Agent Arena data

Cost differences widen precisely on the longest sessions, so the cheapest model for simple tasks is not the cheapest for complex agentic work. Teams running long-horizon agent tasks such as app development can cut bills by re-benchmarking at high task complexity rather than averaging across workloads. The finding also opens the door for Gemini 4 Argon and Xiaomi's MiMo-V2.6 Flash and Pro to challenge OpenAI and Anthropic where budgets are tightest.
