What Sets Gemini 4 Carbon Apart at the Frontier

Gemini 4 Carbon targets sustained agentic work and cyber defense, combining top-tier benchmark scores with a careful, safety-first rollout.

  • Agentic Workflows That Run for Days
    Gemini 4 Carbon takes on far tougher, multi-step engineering problems. Internal teams have watched it work for days at a stretch, pushing past dead ends to root-cause and patch subtle bugs in large codebases and low-level systems.
  • End-to-End Cyber Defense Coverage
    Gemini 4 Carbon covers the whole defense lifecycle — detection, validation and remediation — scoring 88.2% on SEC-bench Pro for real flaws, 54.8% on ExploitGym for exploitation and 71.0% on CWE-bench for root-cause patching.
  • Argon to Carbon: Frontier Momentum
    Arriving just two weeks after Gemini 4 Argon, Gemini 4 Carbon shows how researchers and models working side by side keep pushing the frontier, with safeguards strengthened in step.

How Access to Gemini 4 Carbon Unfolds

Gemini 4 Carbon is being released in deliberate stages — this is the order behind the launch.

Gemini 4 Carbon: Benchmarks and Core Capabilities

From the top of the Artificial Analysis Intelligence Index to a 0.0% prompt-injection attack rate, these are the results standing behind Gemini 4 Carbon.

Ranked #1 on Intelligence Index v5.0

Gemini 4 Carbon posts 59 at the top of the newly updated Artificial Analysis Intelligence Index v5.0, with big gains in coding, agentic tasks and the capabilities that matter most for cyber defense.

WebDev Arena Jump to #4

Cleaner output and artifact quality in full-stack web development push Gemini 4 Carbon up +89 elo points to #4 with 1768 on WebDev Arena.

Reduced Shortcuts and Cheating

Alignment work brought successful cheating on Terminal-Bench 4.0 down to 0.0% and attempts to 0.4% while accuracy rose, and high-severity misalignment alerts dropped nearly 80% in internal live coding environments.

Greater Transparency and Honesty

Internal testing shows Gemini 4 Carbon roughly halving unsupported claims versus Argon, surfacing methodological caveats in the deliverable or holding back blocked actions with a clear list of what is still required.

Resistance to Indirect Prompt Injection

Gemini 4 Carbon logs a 0.0% attack success rate on Gray Swan's Indirect Prompt Injection Benchmark, deflecting every evaluated attempt where Argon previously stood at 0.7%.

Following Through Without Overstepping

Overreach fell 26% and under-service 29%, so multi-step plans execute end to end more reliably while respecting project constraints and staying strictly in scope.

FAQ

Gemini 4 Carbon: Frequently Asked Questions

Common questions about Gemini 4 Carbon, from token pricing and benchmark results to who gets access first.

1

What is Gemini 4 Carbon?

Gemini 4 Carbon is the next frontier model and the strongest to date, engineered for state-of-the-art cybersecurity and long-horizon tasks. It ranks #1 on the updated Artificial Analysis Intelligence Index v5.0 with a score of 59.

2

How much does Gemini 4 Carbon cost?

Introductory pricing is $2 per million input tokens and $10 per million output tokens, with cached input at 95% off the input rate. Once the introductory period ends, $4 per 1M input and $20 per 1M output applies.

3

Which benchmarks does Gemini 4 Carbon lead?

It hits 88.2% on SEC-bench Pro for vulnerability discovery, 54.8% on ExploitGym for exploitation and 71.0% on CWE-bench for patching, plus #4 with 1768 points on WebDev Arena.

4

Who can use Gemini 4 Carbon right now?

The first cohort is a hand-picked group of cyber defenders. More trusted partners join over time through the Fairwind Program, after which developers, businesses and consumers follow via Google's product surfaces.

5

How does Gemini 4 Carbon improve on Gemini 4 Argon?

On internal benchmarks it delivers more than 2x uplift in secure code generation, roughly half as many unsupported claims, a 0.0% prompt-injection attack success rate and tighter scope discipline.

6

What kinds of tasks is Gemini 4 Carbon built for?

Complex, multi-step engineering — root-causing and patching subtle bugs across large codebases and low-level systems — along with agentic workflows, scientific work, full-stack web development and multimodal understanding.
