Why we picked it

Google 的 Gemini 4 Flash 快发布了，但更实用的是：没买 Ultra 的话，Gemini 4 Carbon 现在就能在 Google 搜索 AI Mode 里免费用。想先摸底 Gemini 4 表现的人可以马上去搜索里试。

据 Andrew Curran 在 X 上发布的消息，Google 的 Gemini 4 Flash（代号 Hydrogen）发布时间临近。该消息没有给出具体日期或参数，仅表示发布窗口已经很近。

同一条消息还提到一个实用信息：代号 Carbon 的 Gemini 4 已经在 Google 搜索的 AI Mode 中上线。也就是说，没有 Google AI Ultra 订阅的用户不用等 Ultra 套餐，现在就能在搜索 AI Mode 里体验 Carbon 的实际表现，相当于免费试到了此前仅限订阅用户的模型。

Gemini 4 Flash 对应上一代 Flash 的定位，预计是 Gemini 4 系列中面向低延迟、低成本场景的版本。通过搜索入口让免费用户先接触 Carbon，也为 Google 在 Flash 版发布前收集更广范围的真实使用反馈留出了空间。

DeepMind releases AlphaGenome 2 DNA model with doubled variant detection

The move from tissue-level averages to single-cell-type resolution changes what genetics labs can do with variant interpretation: rare-disease teams can now pinpoint which specific cell type a variant disrupts rather than relying on broad tissue signals. Computational biologists and genomics researchers can start testing it immediately via the free AlphaGenome API for non-commercial work. Compared with prior variant-effect predictors, the conditional architecture and cross-modal imputation reduce the need to run every assay before planning follow-up experiments.

Chinese contentGemini 4 Carbon 在 Bug Bunt Bench 得分 57.3，成本仅 Fable 5.2 的四分之一

有人拿 105 个真实 bug 实测了几家旗舰模型，Gemini 4 Carbon 只差 0.7 分追平 Fable 5.2，花费却只有 $31.32 对 $139.65。做代码修复选型的人应该看看这份带价格的榜单，比官方宣传单靠谱。

VIALS-AA leaderboard ranks models on life science visual reasoning

The 29× cost gap between frontier models with a 3-point score spread changes the economics of choosing a model for scientific agent workloads. Teams building lab-automation or biotech analysis tools can use the per-task cost and turn counts to pick models that fit their budgets. The 19-point deficit of open weights models like Kimi K3.1 Pro also marks a concrete ceiling for on-premise deployments.
