Gemini 4 Argon is here, and Maps can now help with your day

What's new

Google has made Gemini 4 Argon available in the Gemini app for Google AI Pro and AI Ultra subscribers. Google's own page mentions no regional restrictions, but it is not clear whether the model is already open to users in Denmark and the EU.

At the same time, Google is telling AI Ultra users that Argon will soon replace Deep Think, and urges them to switch to Argon when they need deeper thinking. Deep Think is currently a thinking level in Gemini 3.1 Pro, alongside High, Medium and Low, and it was last updated in February. There is no date for the replacement, and it is unclear whether all of Gemini 3.1 Pro is being phased out or only the Deep Think mode.

On top of that, the Gemini app has received an expansion of Personal Intelligence. This is the feature that lets Gemini use your own data to give more personal answers. If you give permission, it can now use your Google Maps searches and saved places together with Google Calendar. Google announced it on X on October 22, 2026.

What's smart

The Maps expansion makes Gemini more like a personal assistant. Google's example is a list of restaurants you want to try. Gemini can figure out where your last meeting on the calendar is and suggest your saved places nearby.

Before the expansion, Personal Intelligence could already use Search, Maps, Shopping, News, Google Flights and Hotels. Now your own saved places and your daily schedule are included. The feature can be turned on in Gemini's personalization settings, so you are in control. It arrived the same week Personal Intelligence reached Android Auto.

Argon is meant to be the model you choose when a task requires more thorough reasoning, meaning the model spends more time thinking a task through.

Cheaper or better?

Google promises better reasoning with Argon, but the sources contain no benchmarks, speed figures or comparison with competitors such as ChatGPT or Claude. The same goes for the Maps feature: no pricing or comparisons have been provided for it.

On pricing, however, the picture is clear. According to an earlier article from October 3, 2026, AI Pro costs $19.99 a month, and the article says AI Pro gets access to Deep Think. AI Ultra costs $199.99 a month. These are US prices, and Danish prices are not given in the sources. The sources do not say whether Argon costs extra.

What it's good for

Google urges Ultra users to switch to Argon when they need deeper reasoning.

The Maps feature is good for everyday life: finding a place to eat after a meeting, or making use of the places you have saved anyway when you are on the go. It requires that you have Personal Intelligence and give permission. Whether it works in Denmark and the EU is not stated in the sources, so check the settings in your Gemini app.
