How to Use Gemini 4 Argon and Tasks Mode in the Gemini App

Google rolled out Gemini 4 Argon to Google AI Pro and Ultra subscribers in the Gemini app on 13 October 2026. The frontier model delivers stronger reasoning on complex work and pairs with a new Tasks mode that keeps working after you step away.

If you hold a Pro or Ultra plan, you can switch to Argon today and assign multi-step jobs across connected Google services and partner apps. Free users stay on earlier models for now.

What Gemini 4 Argon Changes in the App

Argon answers more directly and reduces hedging or filler. On longer jobs it shares progress more often so you stay informed without constant check-ins.

Coding gains are notable. On macOS the Gemini app now includes Google Antigravity’s agentic coding interface, letting you move between conversation and code generation in the same window.

Tasks mode sits behind a simple toggle in the main chat. Once enabled, Gemini continues work across your Google apps and more than 40 connected services even when your computer is closed.

Who Can Access Gemini 4 Argon

Only Google AI Pro and Ultra subscribers see Argon in the Gemini app and in AI Mode in Search. Ultra subscribers also gain Argon inside Google Antigravity.

Developers access the model through the Gemini API in Google AI Studio and the Gemini platform. Introductory pricing runs until 30 November 2026.

The rollout is global. Some accounts may see the option appear gradually after the announcement.

How to Switch to Gemini 4 Argon

1. Open the Gemini app on mobile, web, or desktop and sign in with the Google account that holds your Pro or Ultra subscription.
2. Tap or click the model picker inside the prompt box (often labeled with the current model name such as Flash or Pro).
3. Select Gemini 4 Argon from the list. The option appears only on eligible paid plans.
4. Start a new chat or continue an existing one. Argon applies to the conversation from that point.

If Argon is missing, wait a few hours and check again. Google noted the rollout reaches accounts over time. Confirm your subscription is active under Google Account settings or the Gemini app menu.

How to Enable and Use Tasks Mode

Tasks mode lets Gemini handle multi-step work in the background.

1. In the main chat window, look for the toggle that switches between Chat and Tasks.
2. Select Tasks. The interface updates to accept a goal rather than a single reply.
3. Describe the outcome you want. Examples include “Summarise my unread emails from this week and draft replies for the top three,” or “Research flights for a trip to Tokyo next month and add options to a Google Doc.”
4. Confirm or adjust the plan Gemini proposes. Once started, the task continues even if you close the app or shut your computer.
5. Check back later for progress updates and the finished result.

Connected apps expand what Tasks can do. Gemini now links to more than 40 services including Instacart, OpenTable, Adobe, and Shopify. A task can therefore order groceries, book a table, or generate design assets without you staying online.

Practical Tips for Better Results

• Set the thinking level to High when the model picker offers it. This improves performance on large coding or research jobs.
• Break oversized requests into clear stages if the first attempt stalls. Argon handles long outputs (up to one million tokens) but benefits from explicit scope.
• Review progress updates. Argon surfaces status more frequently than earlier models, so you can intervene early if the direction drifts.
• Test Tasks on a small job first. Confirm the connected apps you need are authorised under Gemini settings before assigning high-stakes work.
• Pair Argon with existing Gemini features such as connected Google Workspace tools. See our guide on analysing data with Gemini in BigQuery for related workflows.

Device and Plan Notes

The Gemini app update applies to mobile, web, and desktop. The Antigravity coding interface is currently limited to the macOS Gemini app. Tasks mode is available in the Gemini mobile app, the Mac app, and gemini.google.com, subject to regional availability notes on Google’s help pages.

Pro costs $19.99 per month in the US; Ultra starts higher and includes additional limits and features such as full Antigravity access.

Conclusion

Gemini 4 Argon and Tasks mode give Pro and Ultra subscribers a clearer path from prompt to finished work. Switch the model in the picker, toggle to Tasks, and let Gemini continue across connected apps while you focus elsewhere.

Check the official Google posts for the latest rollout status and any regional limits. Once available on your account, the combination of stronger reasoning and background tasks is ready to use today.
