Google continues to expand the Gemini desktop app, with several unreleased capabilities now in development, including Tasks Mode, a revamped Gemini Spark, and deeper computer use. TestingCatalog recently spotted a new “Additional sandbox options” setting under the computer use section. Its description suggests Gemini could operate outside selected folders, access the internet, and work across other apps without requesting approval for every step. High-stakes actions, including purchases or approving legal documents, would still require human confirmation.
The setting points toward a general-purpose computer use mode in which Gemini can carry out longer workflows across the desktop instead of remaining limited to specific folders or predefined permissions. The capability is currently associated with trusted testing, and Google has not announced when it will reach regular users.
The timing is notable because Google officially introduced Gemini 4 Argon on September 30. Argon is initially being provided to selected cybersecurity experts through Google’s Fairwind program, with broader access set to follow gradually. Google has not confirmed when Gemini Ultra subscribers will receive it.
Argon is also being evaluated specifically for computer use. Google reports results for benchmarks including Agent’s Last Exam and OSWorld 2.0, making the model a plausible candidate to power more autonomous desktop workflows. However, Google has not confirmed any connection between Argon and the capabilities now appearing in the Gemini desktop app.
The direction fits Google’s broader desktop strategy. Gemini Spark is already positioned as a personal agent for multi-step research, planning, local file work, and tasks spanning Google services. Broader sandbox permissions could turn the desktop app into a much more autonomous agent capable of operating across the user’s computer while retaining approval gates for sensitive actions.
For now, the computer use changes remain under development, and their presence in trusted testing does not provide a reliable launch timeline. Some Gemini capabilities move from testing to release quickly, while others can remain gated for months.
