Google's Gemini 4 Argon reaches the Gemini app, Search and developers

Sort of. Google first announced Gemini 4 Argon on September 30. Back then, it went only to trusted cyber defenders through a vetting program called Fairwind, because the model is very good at finding security holes. We covered that defenders-only debut at the time.

At that point, Google said the model would reach developers, businesses and consumers "as soon as possible," starting with paying customers. Today is that step.

Think of it like a new restaurant that ran a private tasting for critics first. Now the doors are open, as long as you have a reservation, which in this case is a paid plan.

Here's where Argon is showing up, according to Google and to reporting by 9to5Google:

• Gemini app: Google AI Pro and AI Ultra subscribers.
• AI Mode in Search: also AI Pro and AI Ultra subscribers.
• Gemini API: developers on the paid tier, through Google AI Studio and Android Studio.
• Google Antigravity: the desktop app and command line tool require AI Ultra.

Engadget reports that Google AI Pro costs $20 a month in the US, and Ultra costs at least $100.

The catch: free users and Google AI Plus subscribers don't get Argon yet, Android Police notes. The rollout also isn't instant. The Android Police reviewer, a Pro subscriber, still didn't see Argon in the app when the story ran.

In real life If you pay for Google AI Pro, update the Gemini app and tap the model menu next to the text box. When Argon appears there, pick it, then ask the same question you asked yesterday and compare the answers.

9to5Google reports the model picker now lists four options for paying users: 3.5 Flash-Lite, 3.8 Flash, 3.1 Pro and 4 Argon.

Google's pitch is mostly about style. The company says Argon "answers questions more directly with less hedging, doesn't repeat itself more than necessary, and skips clichés throughout the responses."

In plain terms: fewer answers that open with a compliment, explain three caveats, and then repeat the question back to you. 9to5Google also quotes Google saying Argon "follows style instructions more reliably than any of our previous Gemini models." So if you ask for three bullet points, you should get three bullet points.

For longer jobs, Google says Argon "keeps you in the loop by sharing its progress more often." Engadget adds that it can show responses while it's still thinking, so you aren't staring at a spinner.

Why it matters: most people never read benchmark charts. They notice when an answer is shorter, clearer and closer to what they asked for.

Google bundled a few app changes with the model:

• A tasks toggle: a switch in the main chat window moves you from chat to tasks. Google says Gemini can then work for you "even when you're not at your computer." 9to5Google reports this feature was previously called Spark.
• More connected apps: Gemini now connects to more than 40 apps, including Instacart, OpenTable, Adobe and Shopify, for things like ordering groceries and booking tables.
• Coding on the Mac: the agentic coding interface of Google Antigravity, Google's AI development platform, is now built into the Gemini macOS app. Agentic means the AI writes and runs code in steps instead of just suggesting it.

Google's developer announcement calls Argon a model for long, multi-step work like code migrations and research. Prices are per million tokens, the small chunks of text a model reads and writes:

Argon's introductory price is half of what it will cost from December, so developers have about seven weeks to test it cheaply.

By the numbers: Engadget cites Artificial Analysis, a company that benchmarks AI models. It says Argon matches OpenAI's GPT-6 Astra on its Intelligence Index, a combined score across many tests, at 60% of the cost per task at the introductory prices.

Google also says it will give 10,000 scientists the highest usage tier of Google Antigravity free for 6 months, 9to5Google reports. Applications are open.

Google shared examples from its own teams using Argon inside an internal version of Antigravity, as quoted by 9to5Google:

• Chrome: Argon helped separate core webpage handling from a roughly 6 million line legacy folder inside Chromium's 40 million line codebase. Google says that finished "months of work in weeks."
• Gemma: Argon sped up inference for the small Gemma 4 E2B model by 2.85 times on an Nvidia A100 chip, from about 37,900 to over 108,000 tokens per second.
• YouTube: Argon cut the CPU use of the comments frontend in half. It found that redundant emoji rendering caused nearly 45% of the server overhead.

That last one is a fun detail. Somewhere, a tiny thumbs-up emoji was quietly working overtime.

Google DeepMind published a separate post on Argon for robotics. It calls the model "a step change in physical understanding" and says it scores 87% on the ERQA benchmark, a test of solving physical and spatial problems in 3D. DeepMind says that beats every other frontier model.

The demos read like a sci-fi training montage:

• Spot takes out the trash: Argon controlled a Boston Dynamics Spot robot dog with an arm. It built a simulated copy of a foot-pedal trash bin, practiced, then stepped on the real pedal and dropped soda cans inside.
• Mug rescue: Argon guided a simple robot arm to set a fallen mug upright and put a crumpled napkin inside.
• Sketch to simulation: from a photo of a pen-and-paper sketch, Argon built a physics scene where an Apollo 2 humanoid throws a ball at a stack of boxes.
• Video labeling: Argon labeled a 136 second video of a two-armed ALOHA 2 robot folding an origami fox, flagging pauses and fumbles.

The practice runs use MuJoCo, a physics simulator. The robot can fail in a virtual world as often as it needs, and nobody has to pick up the cans.

What's next: these are research demos, not a product you can buy. But they show Google wants one model to handle both your emails and a robot's chores.

• If you pay for AI Pro or Ultra: watch for Argon in the Gemini app and AI Mode. It may take a few days to reach your account.
• If you use Gemini for free: nothing changes yet. Google hasn't said when Argon reaches free or AI Plus users.
• If you build apps: test Argon before November 30, while the API price is half of what it will be in December.
• If you code on a Mac: the Gemini macOS app now includes Antigravity's coding interface, so you can switch from chat to building in one place.
