- Google has opened Gemini 4 Carbon, its strongest model, to all paying developers and Google AI Ultra subscribers, ending two weeks of access restricted to cybersecurity defenders in the Fairwind Program.
- It launches at Gemini 4 Argon's introductory pricing of $2/$10 per 1M input/output tokens, though it spends more tokens on reasoning and verification.
- Google claims Carbon ranks first on CursorBench 4.0, WANDR and AutomationBench at less than half the per-task cost of the next-best outside model.
- An accompanying chart shows alignment metrics: RL training high-severity alerts down 54% vs Argon (0.023% vs 0.050%), attempted cheating on Terminal-Bench 4.0 audit down 9x to 0.4% with 0% successful cheating, and internal deployment alerts down 80% (0.016% vs 0.078%).
