AI Studio Build 测试 Ultra 模式
TestingCatalog 在 Google AI Studio Build 的模式下拉菜单中发现尚未发布的 Ultra 选项，它与 Plan、Build 及此前发现的 Security 模式并列；其说明称会使用“高级技能和工具”，但具体能力尚不清楚。该媒体在早期测试中发现，即便使用 Gemini 3.8 Flash，通过该流程生成的成果也相当完整，并推测 Ultra 在应用生成上投入了更多思考。Ultra 是否与 Google 已宣布的 Gemini 4 Argon 有关、是否需要 Ultra 订阅，均未得到确认。
TestingCatalog 认为，该模式可能帮助开发者应对更复杂的构建任务，但其与 Gemini 4 Argon 的关联及订阅要求仍未确认。
Google is working on a new Ultra mode for Google AI Studio Build. We spotted the unreleased option in a mode dropdown alongside Plan, Build, and the previously discovered Security mode, which checks apps for vulnerabilities. Ultra’s description says it uses “advanced skills and tools,” but the specific capabilities remain unclear.
In our early tests, generations produced through this flow were quite comprehensive despite using Gemini 3.8 Flash. Based on those results, Ultra appears to devote more thinking effort to app generation than the standard flow. This could help developers tackle more complex builds, although the tests don't show how the mode allocates reasoning or which additional tools it uses.
The feature could fit Google’s broader push toward longer coding workflows. Google has announced Gemini 4 Argon and says it will begin wider access for paid API customers and Google AI Ultra subscribers after an initial testing phase. The announcement provides no firm release date.
