If you pay for Google AI Pro, your Gemini changed yesterday.
Google put its newest model, Gemini 4 Argon, into the Gemini app for Pro and Ultra subscribers on Tuesday.
You might not notice, though. The app often picks the model for you.
So today's job is simple: make sure you're actually using the thing you pay for. Then give it a job worth its time.
Google's pitch is short. Argon "answers questions more directly with less hedging, doesn't repeat itself more than necessary, and skips clichés throughout the responses."
(If you've ever asked an AI a yes-or-no question and got three paragraphs back, you know why that line made the announcement.)
An independent tester, Artificial Analysis, puts it level with OpenAI's GPT-6 Astra on its Intelligence Index.
Right after this: how to switch Argon on, and three jobs to give it this week.
Now a quick word from today's sponsor.

Who gets it
Google AI Pro ($19.99 a month) and Ultra.
Free and AI Plus users don't get it, for now.
Switch it on
Open the model picker in the Gemini app and choose Argon by hand.
If you leave it on automatic, Gemini decides which model answers each message. Some answers will be Argon. Some won't.
You can check: the model name shows in the response details on your phone, and at the end of the thinking steps on the web.
You'll also see a thinking level. Low, Medium or High. Use High for the hard stuff.
Three jobs to give it this week
Argon earns its keep on long, messy work, so save it for the big jobs, not quick questions.
Copy any one of these:
1. Here is a contract I've been sent: [paste]. List every clause that costs me money or locks me in, in plain English, with the clause number. Then give me the three questions to ask before I sign.
2. I run [your business]. Here are my numbers for the last three months: [paste]. Find the one change most likely to add profit next month. Show the math.
3. Plan [your project] week by week for the next 8 weeks. Flag the three steps most likely to slip, and what I should do if they do.Number 1 is the one I'd try first. (It's a first read, not a lawyer. But it'll tell you which clauses to ask a lawyer about.)
Three things to know before you rely on it
It has a limit, and it's based on how much work you give it, not a set number of messages. It resets every five hours, with a weekly cap on top. Hit it and the chat carries on with a lighter model, Flash-Lite.
It doesn't upgrade everything. Picking Argon in chat doesn't change Deep Research, image generation, or the Gemini helper inside Gmail and Docs.
Not everyone's convinced. Bloomberg reported that some Google employees say Gemini 4 does well on tests but struggles with some real coding work. Google disputes that. Check the important stuff once.
The new Tasks toggle
There's a second change in the same update.
Next to chat, there's now a Tasks option. Google says that when you choose it, "Gemini can work for you even when you're not at your computer."
Gemini now also connects to more than 40 apps, including Instacart, OpenTable, Adobe and Shopify.
Google's post doesn't say how purchases get confirmed. So start with tasks that don't spend money: research, planning, drafts.
Should you upgrade for it?
If most of your AI use is emails and quick questions, the free models are fine. Keep your $20.
If you feed it contracts, spreadsheets or long projects every week, it's worth a month to test.
Make it stick
Take the hardest prompt you used last month. Run it in Argon and in your usual model, side by side.
Keep whichever answer you'd actually send to a client.
Models keep changing. A setup that works on whichever one you use stays useful. That's the whole idea behind The One-Person Company Playbook.
It's the complete setup for running a business where AI does the work of a full team. Inside:
A company folder with your brief, pipeline tracker and invoice log already laid out, so any AI picks up where you left off
Thirty AI roles across six departments, from sales to finance, ready to use
Six jobs that run on a clock: the morning briefing, follow-ups, invoice checks and more
The step-by-step path from picking a business model to your first paying customer
Works on Claude, ChatGPT, Gemini or Grok, whichever you already pay for.
The catch: it takes about eight hours over a weekend to set up. After that, it's yours. $97, one-time (down from $297).
Talk tomorrow,

P.S. Run your hardest prompt in Argon and your old model, then hit reply: which one won?
