Beginning Dec. 1, each million input tokens will cost $4 and each million output tokens $20, double the introductory rates.
Google’s Nov. 10 announcement lists prices at $4 per 1 million input tokens and $20 per 1 million output tokens, each double the introductory price of $2 and $10. The schedule applies to Carbon’s paid API offering; introductory rates remain in effect through Nov. 30.
Developers can use the API through Google AI Studio, while businesses can access Carbon through Gemini for business. Google describes the model as designed for complex coding and scientific research, and says it uses more tokens than Gemini 4 Argon. Because charges depend on token volume, a customer’s total cost will vary with usage.
Google has not specified a start time or time zone for the rate change. EconoTimes previously covered Google’s expansion of Carbon access and the API pricing schedule.
