Google AI Studio Build spotted testing an Ultra mode with advanced skills and tools
Overview
Google is reportedly developing an Ultra mode for AI Studio Build, according to Testing Catalog, which spotted it alongside Plan, Build, and a previously seen Security review mode.
The report describes Ultra mode as building with advanced skills and tools, but gives no details on which tools or skills it uses.
The report also does not say whether Ultra mode will require a Google Ultra subscription. Testing Catalog suggests these modes may be built to work with Gemini 4 Argon, though this is the author's inference rather than a confirmed detail.
