Google announced Gemini 4 Argon on September 30, 2026, but "announced" and "available" are not the same thing this time. Argon is rolling out in stages. Here is who has it, who is next, and what Google hasn't said yet.
The Gemini 4 Argon rollout, step by step
- Now: trusted cyber defenders. Since September 30, 2026, Argon has been available to a vetted group of security teams through Google's Fairwind Program, and to teams inside Google.
- Soon: paid API customers and Google AI Ultra. Google says these two groups are next. It uses the word "soon" and gives no date.
- Later: everyone else. Wider access for more developers, businesses and people on other plans is expected after that, but Google hasn't shared a schedule.
Why is Gemini 4 Argon rolling out so slowly?
Because of what it's good at. Argon is unusually strong at finding and exploiting security weaknesses in software. On Google's own charts it finds 85.8% of real-world vulnerabilities in a 20-language test, well ahead of Google's security-tuned Gemini 3.8 Flash Cyber model. That is great news for defenders and a real risk in the wrong hands.
Google puts it simply: "Safely releasing frontier capabilities at this level requires a phased approach." So defenders get a head start to find and fix holes before the model is widely available. Google also describes safety work around misuse, prompt-injection attacks, monitoring for misaligned behavior, and running the model in sandboxed environments.
What is the Fairwind Program?
Fairwind is the name Google gives the program that puts Argon in the hands of trusted cyber defenders first. The announcement does not describe an open sign-up, so for now think of it as an invited program for security teams, not a waitlist anyone can join. If you work in security, watch Google's official channels for how to apply.
Will Gemini 4 Argon be in the Gemini app?
Yes, starting with Google AI Ultra subscribers, Google's top consumer plan. Google hasn't said when (or whether) people on other plans get Argon in the Gemini app. Once Ultra access opens, the usual path will be to pick Argon from the model menu in the Gemini app. We'll confirm the exact steps the day it appears. Our how to use Gemini 4 Argon guide covers every route in.
When will the Gemini 4 Argon API be available?
Paid API customers are part of the next wave, "soon". Google already published the price ($2 per million input tokens and $10 per million output at launch), which usually means the API is close. There is no public model ID yet. Our Gemini 4 Argon API guide shows how to be ready so switching is a one-line change.
Is Gemini 4 Argon free?
Not as far as anyone knows today. Google has not announced a free tier, and the first two public-facing groups (paid API customers and AI Ultra subscribers) both pay. Free access may come later, as it often has with Gemini models, but that is a guess, not an announcement.
What we still don't know
- Exact dates for the API, AI Ultra and wider access
- The official API model ID
- The input context window (Google confirmed a 1M-token output limit)
- Whether there will be a free tier, and which countries get it first
- Timing for Vertex AI and other Google Cloud products
- The knowledge cutoff and a full model card
We check Google's blog and developer docs and update this page as soon as any of these land.
Don't want to wait?
Google's video and image models (Veo 3.1, Gemini Omni and Nano Banana 2) are already live on Lumeta, next to Seedance and Kling.
What to do while you wait
- Developers: get a Gemini API key, build on today's model, and keep the model name in one setting. See the API guide.
- Claude users: wire Gemini into Claude Code with a tiny MCP server now, then swap in Argon later. See connecting Gemini 4 Argon to Claude.
- Creators: Argon won't make your videos anyway. Here's what to use for video.
- Everyone: compare the best alternatives you can use today.
Release date questions
What is the Gemini 4 Argon release date?
Google announced Gemini 4 Argon on September 30, 2026 and made it available the same day to trusted cyber defenders in its Fairwind Program. Paid API customers and Google AI Ultra subscribers are next, "soon", with no exact date.
Can I use Gemini 4 Argon right now?
Only if you are part of Google's Fairwind Program for cyber defenders or work at Google. Everyone else has to wait for the next wave.
When is Gemini 4 Argon coming to the Gemini app?
Google says Google AI Ultra subscribers are among the next to get it, "soon". Other plans have not been given a date.
Is Gemini 4 Argon available in Europe?
Google hasn't published country availability for Argon yet.
Is Gemini 4 Argon the same as Gemini 4 Pro?
No. Argon is the first Gemini 4 model Google has announced, and it uses a new name instead of the Pro and Flash labels. Posts about a "Gemini 4 Pro" are speculation, not announcements.
