Gemini 4 Carbon Gets Wider Access: What Changes and How to Test It. Steele Entertainment

Google announced the availability of Gemini 4 Carbon on October 28, initially offering it to cybersecurity defenders through its Fairwind Program.

The model is now accessible to paying developers and enterprises through the Gemini API in Google AI Studio and Gemini for Business.

According to Google, the introductory rate for Carbon is $2 per million input tokens and $10 per million output tokens, with the rate doubling on December 1.

The company is also extending its program for 10,000 scientists, which began with Argon, to cover Carbon.

In the Gemini app, Carbon is reserved for AI Ultra subscribers, while it is available to developers and enterprises through the paid API.

Engadget, Freepressjournal, and Technobaboy report that Carbon is now accessible to more users after its initial release to select cybersecurity defense companies in late October.

Google has not announced a peso price or a local rollout date for AI Ultra, as noted when the company cut free access to Flash-Lite on October 9.

The Verge notes that Google has not said when, or whether, Carbon will reach AI Pro, AI Plus, or free users.

According to 9To5Google, Carbon ranks #1 on the recently updated v5.0 of Artificial Analysis Intelligence Index at 59, with significant gains in coding, agentic tasks, and cybersecurity defense.

The company introduced Gemini 4 Argon on Wednesday as the flagship of its Gemini 4 generation and is releasing it first to a vetted group of cyber defenders, who will be able to use it without cyber guardrails.

In addition, Google is making its in-car AI assistant more personal by letting Gemini draw on information from connected Google apps, including Gmail, Calendar, Maps, Photos, YouTube, and Search.

Personal Intelligence requires users to choose which apps to connect, and Google has plans to roll out Gemini to children under 13 as well.
