Google DeepMind announces Gemini 4 Carbon for cyber defense
What happened.Google DeepMind announced Gemini 4 Carbon, a frontier model optimized for autonomous cyber defense and long-horizon software engineering.
Why it matters.Long-horizon agentic debugging shifts software maintenance from assisted autocomplete toward fully automated root-cause isolation. Proving reliable multi-day execution on complex kernels allows engineering organizations to automate patch verification across large legacy repositories.
