Gemini 4 Argon

Google · proprietary · gemini-4-argon

Gemini 4 Argon is Google DeepMind's frontier Gemini 4 model for long-horizon software engineering, enterprise knowledge work (legal and finance), cybersecurity defense, and multimodal understanding (charts and video). It expands the output token limit to 1M (up from 64K). As of early October 2026 it is rolling out only to trusted cyber defenders via Google's Fairwind Program; paid API customers and Google AI Ultra subscribers are planned next, with no public Gemini API or Vertex model id yet. Google's launch blog announces introductory pricing of $2 per million input tokens and $10 per million output tokens (cached input 95% off), rising to $4/$20 after an introductory period of unstated length; that pricing is announced but not yet listed on the Gemini API pricing page or purchasable.
