Fairwind
An internal Google project for early safety validation of Gemini frontier models, conducting controlled testing and risk assessment of new models through a trusted group of security experts.
Core Facts
Google first handed Argon to trusted security experts for early validation through a project called Fairwind
Access to Gemini 4 Argon is limited to government users and trusted network defenders within the Fairwind project.
Google's Fairwind program is positioned as a restricted access program targeting government agencies, critical infrastructure operators, and core technology platforms to provide cyber defense capabilities.
Timeline (last 90 days)
Gemini 4 Carbon is first being made available to some cybersecurity defenders, and then its scope will be expanded through Fairwind.
Google first released Gemini 4 on September 30, 2025, but initially it was limited to cybersecurity agencies, and it was fully opened on October 13.
Google said it will expand the Fairwind program to hundreds of additional partners and provide them with model versions without cybersecurity guardrails.
Google is providing a reviewed, network-guardrail-removed version of Argon to hundreds of cybersecurity partners planned for Fairwind.
Google initially showed Argon only to safety teams in the Fairwind program on September 30, and opened it to global developers and enterprises via API on October 13.
Gemini 4 Argon is currently limited to access under Google's Fairwind program (cyber defense direction), with paying API customers and Google AI Ultra subscribers behind it, and no specific timeline.
Argon is currently only available to select partners in Google's Fairwind program, including cyber defenders, governments, telecommunications companies, and a small number of trusted testers, and is not available to general subscribers.
The Fairwind rules narrow access to the Argon model to the specific group of the security team.
Google has established access rules named Fairwind for Gemini 4 Argon.
The Fairwind rules contain four key dimensions: background checks, anti-phishing multi-factor authentication, security team exclusive access, and usage tracking.
