Google Launches Gemini 4 Carbon, Topping Artificial Analysis Index

Google released its new frontier model Gemini 4 Carbon on October 29, only about two weeks after Gemini 4 Argon. Both official announcements and third-party evaluations show the model topping the Artificial Analysis Intelligence Index v5.0 with a score of 59, ahead of Claude Opus 5.5 (58) and GPT-6 Astra (57), putting Google back at No. 1 on the leaderboard.

Confirmed

• Official announcements (GoogleAI, Sundar Pichai, Logan Kilpatrick) confirm Gemini 4 Carbon is Google's strongest frontier model, focused on state-of-the-art cybersecurity and long-horizon task capabilities, improving over its predecessor on most benchmarks, with standout autonomous coding and cyber defense performance
• DeepMind added that Carbon can work on complex tasks for days without stalling or taking shortcuts, delivering high-quality, reliable code; safety guardrails will be iterated based on feedback from the first cohort of cyber defenders before access is broadened
• Artificial Analysis first evaluation: Intelligence Index v5 score of 59 takes the top spot; Coding Agent Index of 59, second only to the Claude Opus series
• Per AA data relayed by Yuchen Jin, Carbon is both stronger and cheaper than Opus 5.5 on agentic tasks (index roughly 59.4 vs 58.4, with lower cost per task)
• Logan Kilpatrick confirmed the model is first available to cyber defenders, with efforts underway to bring it to broader users soon; Reddit users noted there is no public API yet; Prompt Engineering reported pricing is unchanged
• DeepMind CEO Demis Hassabis amplified the launch, calling the model SOTA on key benchmarks and iterating at "lightning speed"; Elon Musk responded that he was impressed

Why it matters

• Releasing two frontier models, Argon and Carbon, within two months shows Google has markedly accelerated its iteration cadence, with many commenters describing the comeback as "Google is BACK"
• Setting SOTA in two high-stakes, high-value areas—cybersecurity and long-horizon autonomous tasks—while opening first to cyber defenders reflects a strategy balancing capability releases with safety guardrails
• Overtaking Claude Opus 5.5 and GPT-6 Astra in head-to-head benchmarks to top the leaderboard may reshape the current frontier model competitive landscape
