Google Launches Gemini 4 Carbon, Topping Artificial Analysis Rankings

Google released its new frontier model Gemini 4 Carbon on October 29, just two weeks after the previous-generation Gemini 4 Argon. The model tops the Artificial Analysis Intelligence Index v5.0 with a score of 59, surpassing Claude Opus 5.5 (58) and GPT-6 Astra (57). Google says its headline strengths are state-of-the-art cybersecurity and long-horizon task capabilities. For now, the model is available only to cybersecurity defenders on a priority basis, with no public API yet.

Confirmed

• Google officially (via GoogleAI, GoogleDeepMind, and a Sundar Pichai repost chain) announced Gemini 4 Carbon as the next frontier model after Argon, claiming it surpasses Argon across all capabilities (m5, m13, m15, m19)
• DeepMind CEO Demis Hassabis said the model is "iterating at lightning speed," achieving SOTA on key benchmarks while combining frontier capabilities with deep safety research; Elon Musk responded that he was impressed (m1, m4)
• Artificial Analysis's initial evaluations: it tops the Intelligence Index v5.0 with 59; on the Coding Agent Index it scores 59, second only to Claude Opus 5.5 (m8, m12, m14)
• AA data shows Carbon is stronger than Opus 5.5 on agentic tasks and cheaper: roughly 59.4 vs 58.4 on the index, with lower per-task cost (m11)
• Google says Carbon can work on complex tasks for days on end without stalling or cutting corners, delivering high-quality, reliable code (m7)
• Due to voluntary participation in the US government's pre-release testing process, Carbon is available this week only to a subset of cyber defenders (via the Fairwind program), with broader access to follow after iterating on safety guardrails based on initial feedback (m17, m18, m7)
• Google has published an official blog post and a full benchmark comparison table covering Gemini 4 Argon, GPT-6 Astra, Claude Opus 5.5, and Claude Fable 5.1 (m9)

Not yet confirmed

• The model currently has no public API; Reddit users and researchers (as relayed by natolambert) complain they can't actually use it, and the timeline for broader availability remains unclear (m6, m18)

Why it matters

• Shipping two frontier model generations in two weeks shows Google's aggressive iteration pace; topping the AA leaderboard marks its return to first place in the race against Anthropic and OpenAI—Reddit users put it as "Google is BACK" (m6)
• The "cyber defenders first, broader access later" release approach, tied to the government's pre-release testing process, points to a new safety-first model for frontier releases (m18)
