Google Deepmind releases Gemini 4 Carbon just two weeks after Argon with gains across the board

Google DeepMind shipped Gemini 4 Carbon two weeks after Argon; it tops the Artificial Analysis Intelligence Index v5.0 with 59 points versus Argon's 50, and leads 15 of 16 of Google's own benchmarks, especially in long-context and security tasks. Independent evaluations show it second on Vals AI (70.36%) and the Agent Arena (+16.2%), fourth in the Code Arena's WebDev category (1,768), and still slightly behind Claude Opus 5.5 in agentic coding, while costing $7.76 per task at the same introductory price as Argon ($2/$10 per million input/output tokens). Google is rolling it out first to selected cybersecurity experts and through the Fairwind Program before wider release.
