Primary source: Google DeepMind: Gemini 4 Carbon is now available. We are the fast, independent index; the vendor’s own page is the source of record for this release.

In the source’s words

“Carbon is our strongest model with frontier performance in cybersecurity capabilities and long-horizon agentic workflows across complex knowledge work, software engineering, and scientific reasoning.”

“After the introductory period expires on November 30, 2026, the price of $4 per 1M input tokens and $20 per 1M output tokens will apply.”

“Argon remains the ideal choice for the majority of software engineering and knowledge work”

What we have not verified

  • We did not run Gemini 4 Carbon or the /swarm preview ourselves.
  • All benchmark rankings, cost-per-task comparisons, safety rates and partner results are Google's own claims; we did not reproduce them.
  • The post gives no API model ID, context window or output limit, and does not say whether the Carbon for cyber variant has the same price.
  • Rollout to AI Ultra subscribers is described as ongoing, so availability on a given account may lag.
