Google unveiled Gemini 4 Argon on Wednesday, its most capable model to date for coding and cybersecurity. It scored 77.9% on DeepSWE v1.1 and achieved just a 0.7% attack success rate on Gray Swan’s indirect prompt injection test, outperforming Claude Opus 5.5 and Claude Fable 5.1 which both reached 1.0%. The model is first available to vetted cybersecurity teams through the Fairwind Program, without built-in cyber guardrails, before reaching paid API customers and Google AI Ultra subscribers. Introductory pricing is set at $2 per million input tokens and $10 per million output tokens.
