## Summary

Google DeepMind has released Gemini 4 Carbon, two weeks after Argon, and it scores 59 on version 5.0 of the Artificial Analysis Intelligence Index, ahead of Argon at 50. Independent evaluations report gains in agentic coding, knowledge work and legal research, while hallucination rises from 4 to 11 percent and runtimes and token counts grow in several tests. Access is limited to selected cybersecurity experts at first, with broader developer and consumer availability planned after further feedback and guardrail adjustments.
