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.

Claude is now available inside mainline Copilot chat, the clearest sign yet that Microsoft's era of exclusive dependence on OpenAI is over. Wave 3 of Microsoft 365 Copilot reframes the platform as model-diverse by design - and positions Microsoft, not any individual AI lab, as the stable layer enterprises should trust.

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.
