Google announced Gemini 4 Argon on September 30, 2026, with initial external access for selected trusted cyber defenders through its Fairwind program. Google said broader access would start with paid API customers and Google AI Ultra subscribers, but gave no date.
Google announced a controlled Gemini 4 Argon rollout
Google positioned Gemini 4 Argon for complex software engineering, enterprise knowledge work and cybersecurity defense. The company also said its internal teams use the model.
Fairwind is Google DeepMind’s program for selected partners working on cybersecurity defense and research. NeoTeo previously covered a separate staged-access policy in its article on Anthropic’s Claude Fable 5.1 and Mythos 5.1.
Who can use Gemini 4 Argon through Fairwind
Google DeepMind says it vets Fairwind participants and prioritizes governments, national cyber authorities, critical-infrastructure operators and core technology platforms. The program has more than 650 partner organizations worldwide; Argon access is limited to a vetted set of those partners.
The safeguards attached to Fairwind access
Participating organizations may use Argon for authorized threat simulation, reverse engineering and malware analysis for defensive or academic research. Fairwind prohibits malicious use and bars organizations from sharing, redistributing or selling access.
Organizations must limit access to internal cybersecurity, incident-response or penetration-testing teams. They must use user-level authentication and phishing-resistant multifactor authentication, and track employee access and use.
What Google says about broader access
Google said its broader rollout to developers, enterprises and consumers would start with paid API customers and Google AI Ultra subscribers. The announcement did not set a rollout date, and its stated starting group does not guarantee immediate access for every Ultra subscriber.
