Google DeepMind announced Gemini 4 Argon, its first new frontier model in months, aimed at long-horizon software engineering, enterprise knowledge work, and cybersecurity defense. It raises output limits to 1M tokens, claims leading scores on several benchmarks including DeepSWE v1.1 at 77.9%, and starts at introductory API pricing of $2/$10 per million tokens. Access begins with vetted cyber defenders in Google’s Fairwind Program before broader paid API and AI Ultra rollout.
Why it matters
Google is back in the frontier race after a long stretch of Flash-only releases and a cancelled Gemini 3.5 Pro. Argon’s cyber-first, limited release mirrors how other labs gate high-capability models, while the 1M output window and aggressive intro pricing are a direct shot at OpenAI and Anthropic’s mid- and high-tier offers.
Google DeepMind announced Gemini 4 Argon on September 30, 2026 — its first true frontier model in months after a stretch of Flash variants and a Gemini 3.5 Pro that never shipped. Argon is positioned for complex, long-horizon workflows in software engineering, enterprise knowledge work (legal, finance), and cybersecurity defense.
The standout technical change is output length: up to 1 million tokens in a single response, up from 64K on prior Gemini models, paired with a large context window. Google reports a new state of the art on DeepSWE v1.1 (77.9% for long-horizon software engineering), leads on its Vals Index for economic-impact knowledge work, and ties or leads on several cyber and coding benchmarks against GPT-6 Astra and Claude Opus 5.5 / Fable 5.1 on Google’s published tables.
Access is phased. Argon is rolling out first to trusted cyber defenders through Google’s Fairwind Program (650+ partner organizations). Google says it is also participating in the US government’s voluntary pre-release model access process. Broader availability is planned for paid API customers and Google AI Ultra subscribers “as soon as possible,” with no firm public date. Introductory API pricing is $2 per million input tokens and $10 per million output tokens (cached input heavily discounted), with higher standard rates after the intro period.
The launch lands one day after Google CEO Sundar Pichai signed the voluntary White House Accord on Super Intelligence alongside other frontier labs.
