Google DeepMind opens Gemini 4 Argon to Fairwind defenders

Google DeepMind announced Gemini 4 Argon on Sept. 30, a frontier model first rolling out to trusted cyber defenders in the Fairwind Program rather than to the public. Introductory API pricing is $2 per million input tokens and $10 per million output tokens, with a 1 million token output limit, up from 64,000, and a 77.9% score on DeepSWE v1.1. Paid API customers and Google AI Ultra subscribers are next, with no public date; Fairwind members and Google internal teams get a version without cyber guardrails.
