The June release is why Gemini Computer Use is listed here as controlling both a desktop and a browser rather than a browser alone. Google's changelog records public preview support for the Computer Use tool in Gemini 3.5 Flash with simplified actions with intents, built-in support for browser, mobile and desktop environments, configurable safety policies, and advanced prompt injection detection.
Mobile is the interesting addition, and no other entry in the directory documents it as a first-class environment.
The word that has not changed is preview. Google's own documentation still warns that as a preview capability, Computer Use may contain errors and security vulnerabilities, and advises against critical decisions, sensitive data, or actions where serious errors cannot be corrected. Nearly a year after the first Gemini 2.5 preview in October 2025, the stage designation has held — which is worth remembering when secondary sources describe it as shipped.
