Google releases Gemini 4 Argon to paying users and API developers worldwide

Gemini 4 Argon is available via API at an introductory $2/$10 per million tokens, and to Pro and Ultra subscribers in the Gemini app. Antigravity access is limited to Ultra, and Google says it ranks first on the Vals Index.

In context

  • Argon is available via API in AI Studio, to Ultra subscribers in Antigravity, and to AI Pro ($20/month) and Ultra (from $99/month) subscribers in the Gemini app and AI Mode in Search. Free users are excluded.
  • Introductory API pricing is $2 per million input tokens and $10 per million output tokens, with cached input 95% cheaper. Ars Technica and Artificial Analysis report rates double to $4/$20 after November 30.
  • Google says Argon ranks first on the Vals Index and cut code rollbacks by nearly a third while raising agentic code submissions 35% internally. Latent Space notes these are internal claims, not controlled measurements.
  • Artificial Analysis places Argon level with GPT-6 Astra on its Intelligence Index at $1.99 per task, with a 15% hallucination rate. Cursor reports 52.8% on CursorBench, on par with Opus 5.5.
  • Google is offering 10,000 scientists free top-tier Antigravity access for six months, and is expanding the Fairwind cyber-defense program to hundreds more partners.

Why it matters

Google revealed Argon a few weeks ago and held back a wider release, citing the potential for misuse. The launch lands as rivals push their own frontier models: Meta's Muse Wonder arrived the same week, and Artificial Analysis lists Opus 5.5 ahead on its Intelligence Index. Restricting the strongest coding access to Ultra subscribers reflects the compute cost of agentic workflows, according to Ars Technica.

What to watch

Watch November 30, when Argon's API price doubles to $4/$20 per million tokens, and whether Google extends Antigravity access beyond Ultra, which it has declined to clarify.
