the frontier just launched invite-only. gemini 4 argon, out sep 30, opens at $2 per million input tokens but access is limited to vetted cyber defenders.
the paid api now waits on clearance.
Context
Verified event date: Google announced Gemini 4 Argon on Sep 30, 2026, rolling it out first to a set of trusted cyber defenders through its Fairwind Program (Google blog; The Verge; Ars Technica, Sep 30). The Frontier (Oct 2) lists introductory prices of $2 per million input tokens and $10 per million output tokens, with developers, enterprises and consumers getting it later and no date given.
Ars Technica notes Google had promised Gemini 3.5 Pro in June, and The Verge says the limited launch lets Google check the model is not misaligned before wider release.
The Sep 30 date, the $2 input price and the limit to vetted cyber defenders match Google's announcement and the coverage. The $2 and $10 are introductory prices per The Frontier. 'The paid API now waits on clearance' is the author's; the sources read describe a Fairwind Program rollout with later general availability and no date.
'the frontier just launched invite-only' is the author's opinion.
