Exciting news: Gemini 4 Carbon (High) from @GoogleDeepMind just made a huge debut on Arena, landing #1 in Text Arena, #2 in Agent Arena, and #4 in Code Arena: WebDev. Back at the top, Gemini 4 Carbon delivers frontier intelligence and reshapes the Pareto frontier across three arenas.
In Agent Arena, Gemini 4 Carbon ranks #2 with a +16.2% net improvement across +21.9K real-world agentic sessions from our global community, surpassing top models GPT-6 Astra and Fable-5.1. At $1.80 median cost per task, Gemini 4 Carbon (High) costs 72% less than the #1 ranked Claude Opus 5.5 (Max).
Its standouts by key signals:
- #1 Steerability (+18.6%): can the model course-correct when you push back?
- #2 Praise vs Complaint (+37.9%): implicit sentiment in users' reactions
- #3 Confirmed Success (+18.7%): explicit “yes, that worked” from users
In Code Arena: WebDev, Carbon scored 1768 pts landing #4:
- Just 2 pts below #3 Claude Sonnet 5.5 (xHigh), at 1770 pts
- 89 pts above #11 Gemini 4 Argon (High), at 1679 pts
By category, it ranks #3 in Gaming and Simulations, and #5 in Brand & Marketing.
In Text Arena, Gemini 4 Carbon (High) is the new #1 with 1528 pts, now ahead of Gemini 4 Argon (High) at #2 with 1520 pts.
Congrats to the @GoogleDeepMind team on this huge milestone!
