Google has rolled out Gemini 4 Carbon, a new AI model fine‑tuned for cybersecurity applications, as OpenAI confronts a family lawsuit alleging its system gave dangerous medical advice.

Gemini 4 Carbon focuses on cybersecurity

The Gemini 4 Carbon model builds on Google’s Gemini 4 architecture but incorporates specialized training data for threat detection, vulnerability assessment, and incident response. Google says the model can analyze code, network logs, and security alerts faster than previous versions, helping enterprises automate routine security tasks while maintaining high accuracy.

OpenAI sued over alleged medical misinformation

A family in California filed a lawsuit against OpenAI, claiming the company’s chatbot provided harmful medical guidance that led to a delayed diagnosis. The complaint alleges that the AI’s advice was “misleading” and caused the plaintiff to forgo professional medical care, resulting in serious health consequences. OpenAI has responded that its systems are not intended to replace professional medical advice and that it continuously updates safety mitigations.
