Overview
- Google made Gemini 4 Argon available worldwide on Oct. 13 to developers, enterprises and paying Gemini app subscribers through API access, AI Pro and AI Ultra plans, and the Antigravity platform.
- The company set an introductory API price of $2 per million input tokens and $10 per million output tokens through November 30, after which rates double, and it offers a 95% discount on cached input tokens during the promotion.
- Argon uses a single 1,000,000 token budget that counts both input and output, which means long prompts reduce the room available for model responses and changes how long-context tasks must be managed.
- Google cites strong benchmark results and internal gains—over 35% more agentic code submissions and nearly 30% fewer rollbacks in Antigravity—while independent tests and some employee reports show mixed results on specific coding tasks.
- Google expanded Fairwind to give vetted cyber defenders an unguarded Argon, reported a 0.7% prompt‑injection success rate on Gray Swan, and offered 10,000 scientists six months of high‑tier Antigravity access, moves that shape who can use Argon at scale and how enterprises will adopt it.
