Google introduces Gemini 4 Argon with initial access for cybersecurity partners

Google announced Gemini 4 Argon on September 30, beginning access with selected cybersecurity defenders in its Fairwind program. The company said the model targets extended tasks involving programming, finance, legal work and security.

Argon supports up to 1 million output tokens, an increase from the previous 64,000-token limit. Google announced introductory charges of $2 for each million input tokens and $10 for each million output tokens. Those rates will later rise to $4 and $20, respectively.

Google said its teams already use Argon for research, code migrations and engineering work. The company also said the model can discover software vulnerabilities, check them and generate fixes. Those security capabilities underpin its decision to expand access in stages.

Google plans to use early evaluations to improve safeguards before broader distribution, with paying API users and Google AI Ultra subscribers first in line. Its announcement did not specify a general release date.
