Gemini 4 Carbon 是人工分析智能指数v5上的新一号
见模型页面
Google的Gemini 4 Carbon是人工分析智能指数v5上的新一号，在人工分析编码Agent指数上仅次于Claude Opus 5.5
Gemini 4 Carbon在Intelligence Index v5上得分59分，由复杂推理，知识和科学任务中的主要表现所驱动。 它在编码和知识工作方面也有很大收益，尤其是与其他Gemini模型相比，但它并没有在所有这些领域领先。
与Gemini 4 Argon的发布一样，Gemini 4 Carbon正在向选定的用户推出，尚未公开。 Google提供50%的发布折扣，没有确认结束日期。 我们所有的图表和数字都采用了Gemini 4碳和Argon的标准定价。
Gemini 4 Carbon 关键结果推理高：
Gemini 4 Carbon领先"情报指数v5"，在9个指数评价中的4个中得分为#1:HLE-Diamond,Terminal-Bench-Science,AA-Omniscience，自动化Bench-AA. 碳在别处取得巨大收益，但在编码和知识工作方面并不领先
仅以Claude Opus 5.5为编码后agents：用Antigravity CLI,Gemini 4 Carbon(高)在人工分析编码Agent指数上仅以Claude Code和Claude Opus 5.5(最大，62. 碳在终端-Bench 4.0 (64%)和FrontierCode v1.1 (51%)中排名第二，以56%的成绩落后于Claude Opus 5.5 (最大). Google在这方面历来表现不佳，因此这一改进突出。
改进了代理知识工作，但尚未领先：在AA-Briefcase上，Gemini 4 Carbon (高)分数为1609 Elo，比Gemini 4 Argon(高，1483)提高126分，但仍落后于模型，包括Grok 4.7 (高，1638),Muse Wonder (最大，1659)和Kimi K3.1 Pro (1678). 最大的收益来自演示，293 Elo升至1598，同时分析质量提高120分至1671分
可比整体情报，每个任务的成本比Claude Opus 5.5低：采用标准定价，Gemini 4 Carbon每情报指数任务的成本为7.76美元，比Claude Opus 5.5(最大，10.04美元)低23%，但为~1.2x GPT-6 Astra(最大，6.25美元). 它每个任务使用123k输出令牌，比Claude Opus 5.5(最大，173k)少了29%. 在4美元/20美元的标准定价中，每个任务的费用与Gemini 4 Argon(7.68美元)一致，同时在情报指数上得分更高9分
领先AA-Omniscience v1.1分，低幻能分：Gemini 4 Carbon 在最近更新的AA-Omniscience v1.1分上得分54分，比Claude Opus 5.5分(最大48分)领先6分，比Gemini 4 Argon分(46分)领先8分。 准确度(%正确度)比阿尔贡高出10分到58%，而它的幻觉率从4%上升到11%. 这仍然是任何型号中第二低的，仅落后于阿尔贡，而Claude Opus 5.5(最大)和GPT-6 Astra(最大)均为50%.
主要模型细节：
上下文窗口：1M 令牌
多种模式：文本、图像、视频和语音输入，以及文本输出
定价：每1M个输入/输出符4美元/20美元，与Gemini 4 Argon标准定价相同，折扣为50%. 缓存输入令牌获得95%的折扣(按标准定价，每1M美元0.20美元)

Gemini 4 Carbon is the new #1 on the Artificial Analysis Intelligence Index v5
See model page
Google’s Gemini 4 Carbon is the new #1 on the Artificial Analysis Intelligence Index v5, and second only to Claude Opus 5.5 on the Artificial Analysis Coding Agent Index
Gemini 4 Carbon scores 59 on Intelligence Index v5, driven by leading performance in complex reasoning, knowledge, and scientific tasks. It also has large gains in coding and knowledge work, particularly when compared to other Gemini models, but it is not leading in all these areas.
As with launch of Gemini 4 Argon, Gemini 4 Carbon is being rolled out to selected users and is not yet publicly available. Google is offering a 50% launch discount, with no confirmed end date. All our charts and figures use standard pricing for both Gemini 4 Carbon and Argon.
Key results for Gemini 4 Carbon with high reasoning:
➤ Gemini 4 Carbon leads the Intelligence Index v5, with the #1 score in 4 of the 9 Index evaluations: HLE-Diamond, Terminal-Bench-Science, AA-Omniscience, AutomationBench-AA. Carbon makes substantial gains elsewhere but is not leading in coding and knowledge work
➤ Behind only Claude Opus 5.5 on coding agents: With Antigravity CLI, Gemini 4 Carbon (high) scores 59 only 3 points behind Claude Code with Claude Opus 5.5 (max, 62) on the Artificial Analysis Coding Agent Index. Carbon ranks second on both Terminal-Bench 4.0 (64%) and FrontierCode v1.1 (51%), behind Claude Opus 5.5 (max) at 56%. Google has historically underperformed in this area and so this improvement stands out.
➤ Improved agentic knowledge work, but not yet leading: On AA-Briefcase, Gemini 4 Carbon (high) scores 1609 Elo, a 126-point improvement over Gemini 4 Argon (high, 1483), but still behind models including Grok 4.7 (xhigh, 1638), Muse Wonder (max, 1659) and Kimi K3.1 Pro (1678). The largest gain comes from Presentation, up 293 Elo to 1598, alongside a 120-point improvement in Analytical Quality to 1671
➤ Lower Cost per Task than Claude Opus 5.5 for comparable overall intelligence: With standard pricing, Gemini 4 Carbon costs $7.76 per Intelligence Index task, ~23% less than Claude Opus 5.5 (max, $10.04) but ~1.2x GPT-6 Astra (max, $6.25). It uses 123k output tokens per task, 29% fewer than Claude Opus 5.5 (max, 173k). At the same $4/$20 standard pricing, its Cost per Task is in line with Gemini 4 Argon ($7.68), while scoring 9 points higher on the Intelligence Index
➤ Leading AA-Omniscience v1.1 score, with low hallucination: Gemini 4 Carbon scores 54 on our recently updated AA-Omniscience v1.1, 6 points ahead of Claude Opus 5.5 (max, 48) and 8 points ahead of Gemini 4 Argon (46). Accuracy (% correct) rises 10 points over Argon to 58%, while its hallucination rate rises from 4% to 11%. This is still the second lowest of any model, behind only Argon, compared with 50% for both Claude Opus 5.5 (max) and GPT-6 Astra (max)
Key model details:
➤ Context Window: 1M tokens
➤ Multimodality: Text, image, video, and speech input, with text output
➤ Pricing: $4/$20 per 1M input/output tokens, the same as Gemini 4 Argon’s standard pricing, with a 50% discount. Cached input tokens receive a 95% discount ($0.20 per 1M at standard pricing)
