Google is rolling out Gemini 4 Carbon to the wider public, positioning it as its strongest Gemini 4 model so far and a direct competitor to frontier systems from Anthropic and OpenAI.
Two weeks ago, Carbon was limited to selected “cybersecurity defenders” through Google’s Fairwind program. Now it’s available via the Gemini API in Google AI Studio and Gemini for business for all paying developers and enterprises, at the same introductory price as Gemini 4 Argon: $2 per million input tokens and $10 per million output tokens. It’s also rolling out to Google AI Ultra subscribers in the Gemini app, AI Mode in Search, and Antigravity.
What’s new in Carbon?
Google describes Gemini 4 Carbon as optimized for tasks that push model reasoning to the limit, including:
- complex, multi‑step coding and debugging
- open‑ended scientific research and data analysis
- long‑horizon agentic workflows across tools and services
- dense legal, financial, and operational document review
On independent benchmarks focused on real‑world workflows, Carbon scores highly on CursorBench 4.0, Perplexity’s WANDR, and Zapier’s AutomationBench, while aiming for lower cost per task than other frontier models.
Agent “swarm” in Antigravity
Alongside the model, Google is previewing a new /swarm feature in Google Antigravity. A single prompt can spin up a coordinated team of agents that you can monitor in real time. Developers can:
- assign Carbon to roles that need deep reasoning, such as architecture, coordination, and auditing
- pair it with faster, lighter models in parallel, isolated workspaces
- add adversarial verifier agents that test every proposed change
Why it matters
Carbon’s launch, coming shortly after Gemini 4 Argon, signals Google’s push back to the front of frontier AI development. Beyond benchmarks, Google highlights early use in cybersecurity (vulnerability discovery and patching), financial intelligence, and scientific workflows such as code verification and lab data analysis.
However, it’s still unclear if or when Gemini 4 Carbon will reach lower‑tier or free Gemini users; for now, access is limited to paying customers and AI Ultra subscribers.
