Gemini Enterprise: Use Gemini 3.5 Flash (GA)

Gemini 3.5 Flash is generally available (GA) in the Global, US, and EU regions with Gemini Enterprise. Users can select it in the model selector dropdown within the Gemini Enterprise app assistant and in Agent Designer.

As Gemini 3.5 Flash is the current GA Flash model, Gemini 2.5 Flash is removed from the model selector. Administrators can't toggle Gemini 3.5 Flash off.
