Google announced Gemini 4 Argon, a frontier model built for sustained deep reasoning across long workflows in software engineering, enterprise work, and cybersecurity defense, previewed by Sundar Pichai.
Early access is restricted to trusted cyber defenders via the Fairwind Program, plus participation in the US government's voluntary pre-release process; broader rollout starts with paid API customers and Google AI Ultra subscribers.
Pricing: introductory $2/M input and $10/M output tokens, cached input at a 95% discount, rising to $4/$20 after the intro period.
Output limit raised from 64K to 1 million tokens, enabling hundreds of thousands of tokens in a single trajectory.
It reportedly matches GPT-6 Astra on the Artificial Analysis Intelligence Index at 60% of the cost per task at discounted prices.
