Google Unveils Gemini 4 Argon, Gated to Cyber Defenders First (September 30, 2026)
Google announced Gemini 4 Argon on September 30, a flagship model it says leads rivals on software engineering and knowledge-work benchmarks, with a 1 million token output limit. Access begins with security teams in its Fairwind program, then paid API customers and AI Ultra subscribers once US government pre-release checks finish. Introductory pricing of $2 per million input tokens and $10 per million output tokens matches Claude Sonnet 5.5 and GPT-6.1 Sol, then doubles. Argon still trails OpenAI's Astra and Claude Opus 5.5 on several benchmarks.
So what
Three labs now sell comparable models at the same list price, so cost per task and reliability will decide more than headline scores. If your product runs on a single model vendor, ask engineering this month to test a second model on your own tasks and to model the post-introductory price of $4 and $20.
Hype check
The benchmark results are Google's own and not yet independently verified, and Argon is not generally available.
Confidence: Established fact on the announcement and pricing; benchmark leadership is company-reported.
