# Gemini 4 Carbon

Google DeepMind 于 2026 年 10 月 28 日发布的前沿人工智能模型，侧重网络安全防御与长周期任务，初期仅向受信任的网络安全人员开放。

Gemini 4 Carbon is a frontier artificial intelligence model announced by [Google DeepMind](/zh/organizations/google-deepmind.html) on 28 October 2026. [Google](/zh/organizations/google.html) describes it as its most capable model, with gains in cyber defence and long-horizon task execution.

## Release and availability

Carbon uses the same safety and safeguards stack as [Gemini 4 Argon](/zh/works/gemini-4-argon.html), released on 30 September. At launch it was available only to a small group of vetted cyber defenders; Google plans to widen access through the Fairwind Program to more trusted partners and then to developers, enterprises and consumers. Google says it is taking part in the US government's voluntary pre-deployment testing process for frontier models.

On 10 November 2026 Google made Carbon generally available to developers, enterprises, scientists and consumers: paying developers and enterprises can use it through the Gemini API in Google AI Studio and Gemini for business, and Google AI Ultra subscribers in the Gemini app, AI Mode in Search and Antigravity[^s4].

## Evaluation

Carbon ranks first on the Artificial Analysis Intelligence Index v5.0 with a score of 59, and fourth on WebDev Arena with 1,768 points. Google's cybersecurity results, measured with guardrails disabled, were 88.2% on SEC-bench Pro for vulnerability discovery, 54.8% on ExploitGym for exploitability validation and 71.0% on CWE-bench (Collinear) for root-cause remediation. Google also reports that it generates secure code more than twice as often as Argon, cuts high-severity misalignment alerts by nearly 80%, and reduces the success rate of Gray Swan indirect prompt injection attacks to 0.0%.

## Pricing

Introductory pricing matches Argon at US$2 per million input tokens and US$10 per million output tokens, with cached input billed at a 95% discount; after the introductory period the prices are US$4 and US$20 per million tokens.
