Google launches Gemini 4 Carbon at Argon prices for select cyber defenders

Top News · 859 HN points

Gemini 4 Carbon is Google’s next frontier model, arriving two weeks after Gemini 4 Argon at the same introductory token prices. Google reports more than twice Argon’s success rate at generating secure code in internal tests.

Here's what changed:

• Input costs $2 per million tokens and output costs $10, with cached input discounted by 95%.
• Artificial Analysis ranks Carbon first on its updated Intelligence Index, with a score of 59.
• Google’s internal teams report that Carbon can work for days on complex, multi-step tasks.

One catch: access is rolling out first to a subset of cyber defenders. More trusted partners will follow through the Fairwind Program, while availability in Google products is planned for later. This is not yet a public developer release.
