Gemini 4 Argon Release Date: Who Has It Now and Who's Next
Updated 2026-10-06
Gemini 4 Argon was announced by Google on September 30, 2026, but it has no public release date yet. At launch it went only to a selected group of partners in Google's Fairwind cyber-defense program. Google says paid Gemini API customers and Google AI Ultra subscribers come next, "as soon as possible", without naming a day. As of early October 2026 Argon was not in the public Gemini API model list, the Gemini app or third-party routers.
Below is what is confirmed, what isn't, and how to be ready on the day it opens.
Gemini 4 Argon release timeline
| Stage | Who | Status (early October 2026) |
|---|---|---|
| Announcement | Google DeepMind (post by Koray Kavukcuoglu) | September 30, 2026 |
| First access | A set of Fairwind Program partners (vetted cyber defenders) | Live since launch |
| Next | Paid Gemini API customers and Google AI Ultra subscribers | Announced, no date |
| Everyone else | Free Gemini app users, free API tier | Not announced |
Google's launch post frames the wider rollout as "rolling out soon" and says it will first gather feedback from early testers while it adjusts safety guardrails. Google also said it is taking part in the US government's voluntary pre-release access process. Both are reasons the general release has no fixed date.
Why only Fairwind partners have it first
Google presents Argon as its new frontier model for long, complex work: software engineering, legal and finance work, and especially cybersecurity defense. Google says Argon can find, validate and patch serious software vulnerabilities, and that for trusted defenders it releases the model without its usual cyber guardrails. That is why the first wave goes to Fairwind, Google's limited-access program for security teams, rather than to the public.
Fairwind access comes with conditions reported at launch: phishing-resistant multi-factor authentication, access limited to internal security, incident-response or penetration-testing teams, and usage tracking per employee. Governments, critical-infrastructure operators and core technology platforms can apply through Google DeepMind's Fairwind page.
What we know about Gemini 4 Argon so far
- Position: the first and only Gemini 4 model announced, and the new top of Google's lineup. Google told Reuters it is larger than its previous "Pro" models.
- Price: $2 per million input tokens and $10 per million output tokens during an introductory period, then $4 and $20. Cached input is 95% cheaper. Google hasn't said how long the intro period lasts.
- Output limit: up to 1 million output tokens per response, up from 64K on earlier Gemini models. This is an output limit, not a published input context window.
- Model ID: not published. Model strings you see on some sites are third-party placeholders.
- Benchmarks: Google published a table where Argon leads most rows; independent leaderboards put it near the frontier rather than clearly ahead. Treat vendor numbers as a starting point.
How to know the moment Argon is released
- Watch Google's own pages. The Gemini API "models" page and pricing page are where a model ID appears first. Google's blog and the Google DeepMind site carry the announcement.
- Check the Gemini app model picker if you have a Google AI Ultra subscription – that is the consumer route Google named.
- Prepare your code now. Build on a Gemini model you can call today and keep the model name in one setting or environment variable, so switching to Argon is a one-line change once the ID is published.
- Budget for long outputs. With a 1M-token output ceiling, a single response can be expensive. Set token limits and spending caps before you test it.
Gemini 4 Argon vs earlier Gemini models
Before Argon, Google's top developer model was the Gemini 3.x Pro line, with output capped around 64K tokens. Argon's intro output price is lower than that line's list price, while its standard price after the intro is higher. If you need something now, the current Gemini Pro and Flash models remain the practical choice until Argon reaches the public API.
