Gemini 4 Carbon on BenchGecko · Google prices its new frontier model like Argon
Gemini 4 Carbon arrives two weeks after Argon at the same introductory price of $2 input and $10 output per 1M tokens, with access limited to cyber defenders for now.
What shipped
Google DeepMind announced Gemini 4 Carbon on 2026-10-28, two weeks after Gemini 4 Argon. Access starts with a subset of cyber defenders and partners in the Fairwind Program. There is no general developer API yet.
BenchGecko added the model to the Google DeepMind provider page today.
Price
Carbon launches at the same introductory price Argon lists on BenchGecko:
- Input · $2 per 1M tokens
- Output · $10 per 1M tokens
- Cached input · 95% off input, $0.10 per 1M tokens
After the introductory period Google says the list price becomes $4 input and $20 output per 1M tokens. BenchGecko stores the current introductory price and will record the change in price history when it happens.
