Google unveils Gemini 4 Carbon with a cybersecurity focus, but keeps wide release on hold
Google announced Gemini 4 Carbon, its newest frontier model, just two weeks after releasing Gemini 4 Argon, highlighting gains in vulnerability detection, validation and remediation. The company says Carbon produces vulnerability-free code twice as often as Argon and scored a 0 percent success rate against prompt-injection attacks in the Grey Swan evaluation, outperforming rival models from OpenAI and Anthropic. Despite the results, Google is not making the model broadly available yet, limiting initial access to select cybersecurity defense partners through its Fairwind program, following the same staged rollout it used for Argon. For businesses weighing which AI vendor offers the most trustworthy cybersecurity tooling, the staged release shows AI companies are treating their own frontier models as something to vet before wide deployment.
