What Google has announced

Google announced Carbon on October 28, 2026, through Koray Kavukcuoglu, whom Lindy's write-up identifies as Google's Chief AI Architect. 9to5Google reports that Google said Carbon is coming soon to developers, businesses and consumers, with cyber defenders getting it first that week.

As of November 3, Lindy found Carbon available only to U.S. government pre-release testers and a subset of cyber defenders in Google's Fairwind Program. It was not in the Gemini API, Google AI Studio, the Gemini app or Gemini Enterprise Agent Platform (formerly Vertex AI). Lindy reports that Google said it would bring Carbon to developers, businesses and consumers as soon as possible, with no date given.

Pricing

Lindy lists Google's announced introductory rates at $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 afterward, with cached input 95% off. Lindy says Google has not said when the introductory price ends, and BenchLM's profile, updated November 10, shows the same $2 and $10 rates.

The earlier Argon release is a separate case. Business Model Analyst reports a separate permissive cyber SKU for Argon at $4 and $20 per million tokens. That report concerns Argon, not Carbon.

What the listing would need to show

The listing is so far reported only by AiBattle_. If it is real, the details that matter are its SKU name, whether it is billable, its region, and whether it is tied to Fairwind access or general availability. Our read: a catalog entry would suggest Carbon is moving toward Google Cloud billing, but it would not by itself mean developers can buy it yet.
