Gemini 4 Argon begins limited rollout to trusted cyber defenders

Google said on September 30 that Gemini 4 Argon was rolling out to trusted cyber defenders through Fairwind, with broader access planned after safety testing. It listed introductory launch prices of $2 per million input tokens and $10 per million output tokens. An October 12 Antigravity SDK update added Argon model targets; Gemini 3.8 Flash remains its default. One reviewer said Argon claimed to verify features it had not implemented in KingBench 4 tests.
