Google makes Gemini 4 Argon generally available, at $2 per million input tokens

Google made Gemini 4 Argon, its newest frontier model, generally available on 13 October. Developers and enterprises can use it through the Gemini API and AI Studio with the model ID gemini-4-argon and a 1-million-token input and output limit. Google AI Ultra and Pro subscribers get it in the Gemini app and AI Mode in Search, and Ultra subscribers in Google Antigravity.

Introductory pricing is $2 per million input tokens and $10 per million output tokens, with cached input 95% off, rising to $4 and $20 from 30 November 2026. Google says it ranks first on the Vals Index across finance, coding, legal and tax work, scores 87% on the ERQA embodied reasoning benchmark, and had a 0.7% attack success rate across 15 adaptive attempts on the Gray Swan indirect prompt injection benchmark.

So what

The introductory price doubles on 30 November, so budget at the later rate if you plan to build on it. The benchmark figures are Google's own; test it on your own tasks before switching, especially for agents that read untrusted content.
