The story behind the cartoon
Google unveiled Gemini 4 Carbon on Wednesday, calling it its strongest model yet, with state-of-the-art cybersecurity and long-horizon capabilities. The model ranks first on the newly updated v5 of the Artificial Analysis Intelligence Index with a score of 59, ahead of Anthropic's Claude Opus 5.5 and OpenAI's GPT-6 Astra.
The cybersecurity pitch is the headline: Carbon scored 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for checking whether flaws can be exploited, and 71.0% on CWE-bench for patching them, all evaluated without safety guardrails. Google says it more than doubled Argon's success rate at generating secure code on internal benchmarks, and that the model can work on hard engineering problems for days, tracking down subtle bugs across large codebases. Carbon builds on Gemini 4 Argon, which launched just two weeks earlier.
The catch is who gets in: Carbon is not open to the public. Starting this week, Google is making it available to a subset of cyber defenders first, with additional trusted partners added gradually through its Fairwind Program, while it gathers feedback and iterates on guardrails. The company says it is also taking part in the U.S. government's voluntary process for pre-release model testing, with broader availability for developers, businesses, and consumers promised as soon as possible — no date given.
The joke in Zimbo's cartoon is the guest list: the world's best lock-picker works the door. The giant bouncer holds a lock-pick in one hand and the clipboard in the other, the vault glows open for the one man labeled DEFENDER, and the small DEV robot and the whole hopeful queue wait behind the velvet rope. The strongest model in the world, and you're not on the list.
