NVIDIA's GTC 2026 keynote unveiled a trillion-dollar order outlook, the Vera Rubin platform, Dynamo 1.0 as an inference operating system, and a landmark Meta partnership; together they make the case that the future of agentic AI runs on a single, vertically integrated stack.

Large language models inherit their deepest vulnerabilities not from sloppy engineering but from the mathematical architecture that makes them powerful. This deep-dive dissects the threat landscape from the transformer's attention mechanism up through infrastructure-level defenses, examining prompt injection, context window attacks, laundering, RAG poisoning, multimodal cross-modal injection, and the emerging challenge of agentic AI security.

At GTC 2026, NVIDIA unveiled NemoClaw, a secure software stack that installs Nemotron models and the new OpenShell runtime onto OpenClaw agents in a single command. The move signals something larger than a product launch: NVIDIA is positioning itself as the indispensable infrastructure layer for the agentic AI era.

Ten of xAI's twelve original co-founders have now departed, including Guodong Zhang, who led Grok Code and Grok Imagine. Elon Musk has publicly admitted the company "was not built right first time around" and is rebuilding from the ground up, weeks after SpaceX acquired xAI in the largest M&A deal in history.
