Google opens Gemini 4 Argon beyond its cyber-defender pilot
Benchmark results, including 77.9% on DeepSWE v1.1, and the internal productivity examples are Google's own claims, not independent reruns. Google's announcement does not say when the introductory period ends. Access is paid, not free.
What was claimed?
Google says developers can now build with Gemini 4 Argon on the paid tier of the Gemini API, and Google AI Pro and Ultra subscribers can use it in the Gemini app. Google announced the model on September 30 with access limited to trusted cyber defenders in its Fairwind Program. Google lists an introductory API price of $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 after the introductory period.
What does the evidence support?
Company claim, independent confirmation unresolved
The release followed a staged path: vetted cyber defenders first, then developers and subscribers. Google also raised the output limit to 1 million tokens, from 64,000, for long multi-step tasks, and says it monitors the model's reasoning and actions for misaligned behavior.
