Google adds computer use to Gemini 3.5 Flash

Summary: Google made computer use a built-in tool in Gemini 3.5 Flash on 2026-06-24, letting developers build agents that see and act across browser, mobile, and desktop environments rather than calling a separate computer-use model. It is available through the Gemini API with a reference implementation, through the Gemini Enterprise Agent Platform, and via a Browserbase-hosted demo, and adds two enterprise safeguards: explicit user confirmation for sensitive actions and automatic task stoppage when prompt injection is detected. Google shows an OSWorld benchmark chart but did not state numeric results in the post text.
Why it matters: Folding computer use into the cheaper Flash tier lowers the cost of GUI-driving agents for testing and knowledge-work automation, and the built-in prompt-injection stop is a direct response to the main security failure mode of these agents.
Follow-up: Watch for the published OSWorld numbers with method, real-world reliability reports, and how the injection-detection safeguard performs against adversarial pages.
