Alphabet introduces Gemini 4 Argon with limited cyber-defender access

Google announced Gemini 4 Argon on September 30, initially making the model available to trusted cyber defenders through its Fairwind Program rather than broadly releasing it. The company set introductory API charges at $2 for each million input tokens and $10 for each million output tokens, while cached inputs receive a 95% reduction. BNP Paribas and Jefferies cited Alphabet's infrastructure and distribution advantages, although Jefferies said real-world performance still needs to be established.

BNP Paribas sees scope for Alphabet to monetize AI through models at different price points and potentially consumer-facing services. Jefferies said the lower pricing could pressure competing standalone models, but stressed that benchmark results must translate into customer use.
